Everything is a computer

Christmas shopping this year really drove home to me how completely the electronics industry has made itself obsolete in recent years. The electronics stores are emptying out. All the gadgets that have been so popular in recent decades -- cameras, camcorders, VCRs, tape recorders, CD players, portable music boxes, dictation machines, game consoles, pagers, PCs, notebook computers, TVs, radios, pocket calculators, GPS navigation devices, synthesizers, mixing consoles and of course telephones (mobile and land based) have all disappeared into smart phones.

But smart phones aren't really phones at all, they are just palmtop computers that include an interface for cellular networks and a phone app. They are called smart phones for marketing reasons -- because the phone companies use them to lock consumers into overpriced network contracts. If photography were the killer app, they would be called smart cameras, which is just as appropriate. The only thing that seems to be keeping the entire electronics industry from being swallowed up by the black hole of Moore's Law is this kind of marketing wheeze and the (rapidly falling) price of screens.

I'm old enough to remember when Radio Shack was a national treasure. Now it's just a place to buy batteries while being harassed by a hard selling salesman from some telecoms oligopolist best known for hating its customers. And in this age of smart hearing aids, robotic assembly lines and fly-by-wire airplanes, its not just consumer electronics that is being computerized.

Mobile business intelligence expectations

There is a discussion of some remarks I made to Ann All at IT Business Edge here, together with some opnions by Howard Dresner.

The interview reflects my opinion pretty well. I see mobile BI as a way to find new types of customers for BI more than as a way to replace existing installations. Too bad I didn't mention salespeople on the road, I think they are an important potential market as well.

Another point is that I think most people who said they expected mobile BI to be in use within 12 months were being too optimistic. The BI Survey 11 will address this question.

Chasing new trends

I'm talking to Tibco about Spotfire. It's an interesting product that I've reviewed before. It seems to me that they are moving more and more into operative BI, which fits the Tibco idea of fast data delivery that fits Tibco very well. They also seems to be putting more emphasis on ROLAP than they used to.

What is interesting is that they are also presenting a social media tool called Tibbr (wonder how they came up with that name!) and a cloud version. There's nothing wrong with this of course, but it seems to me that it doesn't fit their bus and/or ROLAP approach very well.

Their justification for the investment is that some analyst or other is predicting fast growth in this area. This reminds me of what an important ole analysts play in the market. Thanks to the analysts, a lot of BI vendors are jumping on the cloud bandwagon, even though the cloud sales channel is very different from what most BI vendors are accustomed to, and that the idea of mving data off site and then back onsite adds complexity.

Enterprise BI and agility

I'm talking to QlikTech about their new version, coming soon. I'll be publishing the results in the BI Verdict. They are focusing more and more on these bigger accounts. I think this story fits pretty well in my informal series of posts on the subject of agile BI. By coincidence I have already discussed QlikView in a previous post.

QlikTech has a what they call a "land and expand" policy, which means getting a single department on the tool and expanding from there. Actually, all BI companies that can deliver departmental solutions have something similar. The reason for this is simple: The cost of sales for selling to a company that is already using the tool is much lower than for completely new customers. In fact, a lot of BI tools spread through companies from department to department this way.

Now QlikTech is concentrating more on enterprise accounts. So it's interesting to see that the company is moving away from the previous claim that the tool is a replacement for a data warehouse. I think that any attempt on their part to compete as an enterprise solution would just distract them from their end users.

A lot of BI companies go through a similar life cycle as they grow. Most start out as ways to create departmental solutions, which tend to be faster, more agile projects. As they get bigger management tends to concentrate on larger accounts, which means making sure they are acceptable to the IT department. But IT is more interested in keeping processes running than in agile development. As a result, the products tend to become more complex and less suitable to agile solutions.

This is a big issue for QlikView right now because they have grown so quickly in recent years. But currently the company seems to backing away from radical changes in the tool. But it applies to and BI tool that is growing.

Why short projects are part of agile business intelligence

One of the key ideas in agility is the importance of delivering real, testable results without delay. In fact, the Agile Manifesto recommends delivering working software frequently, from a couple of weeks to a couple of months.

Delivery working software with two months may sound a bit extreme, but there is good evidence that short projects are more successful than long projects. In fact, our research in the BI Survey shows that the application should be rolled out to the users less than six months after the product has been selected. We have found the same result year after year in the ten year history of the Survey. Amazingly, project benefits start to fall as early as a month after the product is selected, and continue to fall thereafter. And of the many project parameters we study, none shows as clear an effect on project success as project length.

These results from the BI Survey provide clear empirical support for the idea of using agile methods in business intelligence projects. The results have remained also consistent since we started the Survey ten years ago, long before the idea of agile development or agile business intelligence became popular.

But why do short projects work so much better? Our research shows that the main problems that arise in longer projects are organizational, not technical. Needs change over the course of time, and end users lose interest in the project. Disagreements over the project goals arise. Lack of interest and disappointed end users are a major issue in business intelligence.

And needs certainly do change quickly in business intelligence. For example, another study we carried out shows that three quarters of European companies modify their planning processes one or more times a year. In an environment like this, a project that takes a year to implement is quite likely to be obsolete before it is finished. Even a six month wait can push potential users to look around for a more agile solution.

The problem this creates is that not all business intelligence projects can be carried out within a few months. This is especially true when major data management issues need to be addressed. The agile solution to this is to find way of splitting large projects into smaller ones. The usual argument against this approach is that it creates the risk of reducing efficiency in the long term. But the agile methodology is to measure success in terms of working software delivered in the short term, instead of attempting to meet nebulous long-term goals.

Business Intelligence, the semantic Web and Alltop

My blog is including on the Alltop business intelligence page, and at the time of writing I display their badge on the blog.

According to the site 'The purpose of Alltop is to help you answer the question, “What’s happening?”' Alltop is a 1990's style Web registry maintained by human editors.

But Alltop's business intelligence page has several problems that make it less useful than it could be. The page has fallen victim to a semantic Web style gotcha. Like many other phrases, business intelligence means different things to different people. If you don't disambiguate somehow, a web registry based on a phrase may make no sense.

There are three distinct meanings of the phrase "business intelligence". The first is something about software for analyzing business data -- like my blog. The second is news about businesses, which is interesting but unrelated. These are some of those blogs:

MEED NEWS, EMARKETS.DE, B2B TRADE, DEALBOOK, ARUNDEL BUSINESS NEWS, FOREX TRADING INFO, THE FINANCE KID, ARBITRAGE MAGAZINE, SMALL BUSINESS SUPPORT

The third meaning is based on a completely different meaning of intelligence -- intelligence as in IQ, as opposed to intelligence as in information for analysis. In the sense business intelligence just means being smart about business, which could men just about anything.

So Alltop's business intelligence page contain sites that are not at all related to the #businessintelligence tag on Twitter. A lot of these seem to be advice about sales and entrepreneurship or general management consulting blogs. A few are just political blogs, or blogs about general market or marketing trends. They're fine in their way, I guess, just misplaced. Here's a list:

STATSPOTTING!, WSJ: THE NUMBERS GUY, MANAGE BY WALKING AROUND, BUILDING BUSINESS VALUE, CORPORATE MANAGEMENT STRATEGIES, KNOWLEDGE WORKS, HUSTLEKNOCKIN', THE THINK HERE BLOG, LEAD VIEWS, THE SOLOPRENEUR LIFE, SMEDIO, INTERCALL BLOG, GLOBAL INSTITUTE FOR INSPIRATION, SMALL BUSINESS SUPPORT, RED WING SOFTWARE BLOG, FRED67 B2B REFERRAL CLUB, RESULTS.COM BUSINESS GROWTH TIPS

I'm not criticizing any of these guys, just saying they seem to be improperly categorized.

Also Alltop is syndicating advertising material thinly disguised as blogs. Of course, maybe they're getting paid, what do I know? If not they should be. The following are BI vendors, which may or may not be problem:

RED WING SOFTWARE BLOG, LOGIXML, BIME - SAAS BUSINESS INTELLIGENCE (BI), BLOG.JINFONET.COM, MICROSTRATEGY 101, PANORAMA BUSINESS INTELLIGENCE

In addition, there are several aggregators -- Yahoo, and Beyenetwork twice. These guys can be seen as comptetitors, I guess.

In the end I think that the lack of careful stewardship reduces the usefulness of the site. The problem is that business intelligence is a vague term and needs a semantic Web to be useful. Manual editing in a web registry is a workaround, but it is not being used here to much effect.

Discovering hierarchies in columnar databases

I recently blogged about columnar and Wayne Eckerson asked me for a clearer explanation of what I mean by columnar databases "discovering hierarchies".

For example consider the approach of two well known products, IBM Cognos TM1, which is multidimensional, and QlikView, which is columnar.

My definition of a data model is a structure that is informed by an administrator, or set down in the master data. To me this is different to a structure derived from analyzing the transactions. In the following simple example, let's say I have two sales teams, one for dental hygiene products and one for soap.

If I were designing a data model in TM1, then I could create a hierarchy, which is a set of parent child relationships between the departments and the products they sell. If the soap people cross-sold some toothpaste, it would have no effect on the hierarchy, because it is predetermined by my idea of how my company is supposed to work.

If I were to import the same data in QlikView I could create a report that showed me the relationship between the sales teams and the products without defining the model. Once the data is imported, QlikView recognizes the relationships automatically.

When the soap guys cross-sell toothpaste, QlikView discovrs the new relationship, but the hierarchies stay the same in TM1, because that's how I defined the model. To me this is the key difference. On the one hand the structures are coming directly from the actuals, and on the other hand they reflect my predefined perception (or "model") of what is going on.

So columnar databases typically discover the relationships automatically, and multidimensional databases allows you to define the relationships as you want them. Another way to look at this is that the transactional data drives the master data structure in a colunmar database, but those structures are wired into the multidimensional model.

So which approach is better? It depends on the application.

Is the cloud really the future of business intelligence?

The idea of hosting software off-premises is not new. In fact, software as a service (SaaS) is just a rewording of an older term referring to companies providing the service, application service provider (ASP). ASPs were a very popular investment target during the dotcom era, but not much ever came of the business model. Like so many Internet-based startup ideas in this era, most of these companies disappeared.

In fact, the only major exception to this rule was Salesforce.com, which used to refer to itself as an ASP, before the SaaS term became popular. And indeed Salseforce.com is often taken as an example in discussions of the future of BI as a service, or cloud BI.

But why was the ASP wave a failure and why should cloud computing be different? Even the often quoted success of Salesforce.com is far removed from the company’s once loudly trumpeted goal of replacing all the ERP features of SAP and PeopleSoft. Furthermore, do the forces that could make SaaS more successful than ASP also apply to the BI market?

The main argument offered by vendors in favor of cloud BI is that it is less expensive than the more typical on-premises software. The upfront capital costs of hardware contribute to these savings. The other major factor is that the company is not required to operate separate servers for the BI application.

However, both of these savings result from the investment required to own and operate the hardware for BI software. Similar savings can also be realized with strictly in-house approaches such as server virtualization. Furthermore, the use of Web technology has already eliminated one of the key costs of BI initiatives, which is the cost of rolling out the front-ends to large numbers of users.

Another argument is that mobile devices are driving SaaS BI, but as HTML5 spreads, it is hard to see why mobile devices should require a cloud solution.

We a conducting a survey to find out more about BI in the cloud. If you take part you could win an iPad 2.

I'd also be interested to hear any comments on what I have talked about here.

Data modeling and agile BI

One of the advantage that some analytical tools such as QlikView Spotfire or Tableau claims to offer over the products they call "Traditional BI" is that they can be used without data modeling. According to this claim, data modeling is a major obstacle to agile business intelligence and not needed anyway.

Is it true that data modeling is dead? Has technology found a workaround?
The need for data modeling depends upon the application. Products that promise user friendly analysis without any data analysis are usually intended for a specific type of analysis that does not require any previously specified structure.

A good example of data does not require modeling that retailers gather about their customers. This data comes in big flat tables with many columns, and the whole point to the analysis is to find unexpected patterns in this unstructured data. In this case adding a model is adding assumptions that may actually hinder the analysis process.

However, some types of analyses only make sense with at least some modeling. Time intelligence is an example of a type of analysis that is supported by a data model. Also analyzing predefined internal structures such as cost accounts or complex sales channels is usually more convenient based on predefined structures. The alternative method of discovering the structures in the raw data may not be possible.

Planning is a common area of agile BI, and planning is rarely possible without predefined structures. It is no coincidence that the tools that promise analysis without data modeling do not offer planning features. Planning requires adding new data to an existing data set. In some cases, this includes adding new master data, for example when new products are being planned. Furthermore, there is often a good deal of custom business logic in a planning application that cannot be defined automatically. Most financial planning processes, and the analysis and simulation that goes along with them cannot be carried out on simple table.

In my view the new generation columnar databases are a welcome addition to agile BI. But I also think that their marketing is sometimes a little over the top when it comes to dismissing existing BI solution in this area.

Column oriented databases are not the same as in-memory databases

In recent years, thanks not least to aggressive marketing by QlikTech (or Qlik Technologies as the are now often called) Tableau and Tibco Spotfire, columnar databases and in-memory databases have become very fashionable. Microsoft's VertiPaq engine, which is behind the PowerPivot product, is a good example of a tool that came in on the wave of this trend.

One of the results of these is that there seems to be some confusion about what the terms "in-memory" and "column oriented" mean, and attributes of one are often attributed to the other.

Just to be perfectly clear: A columnar database is not necessarily in-memory, and an in-memory database is not necessarily columnar.

In-memory is a somewhat vague term, since, as Nigel Pendse likes to point out, all databases have to hold data in memory to process it -- the CPU cannot directly access the hard drive. However, I would say that unlike some other tools, IBM Cognos TM1 and QlikView are in-memory. These products load everything into memory before they do anything. If there is not enough memory to fit the entire data set, the load fails and that's that. The same applies to SAP HANA. But unlike QlikView and HANA, TM1 is a multi-dimensional database.

The loading behavior of an in-memory database is much different to the MOLAP engine in Analysis Services, which is fundamentally disk-based but has sophisticated paging abilities to keep as much as the data as possible in memory, or the column oriented Spotfire, which attempts to load everything but uses paging if there is not enough memory.

Columnar is a much clearer and simpler term. It simply means that the data is stored by column instead of by row. There are a large number of analytic databases with this architecture, such as Exadata, SAND, Greenplum, Aster, or Sybase IQ, just to name a few. Some, like Vertica and VertiPaq, even refer to their columnar architecture in their names. Some columnar databases are in-memory, but many are designed to deal with huge amounts of data, up to the petabyte range, and cannot possibly hold it all in memory.

By the way, what got me off on this rant is actually this blog about Endeca Latitude 2 which actually equates the two technologies, and a Linked-In discussion the author started (which is private, so I can't link it here) with the title "Is Data Modeling Dead?"

The idea in memory databases kill data modelling comes from the fact that columnar databases are often used to discover hierarchies, and a whole generation of so-called "agile" in-memory database tools use this method. But in-memory multi-dimensional databases are still around and still very useful for analyzing data on well defined structures such as financial data.

The end of Essbase Visual Explorer

I talked to Tableau and Oracle on the same day recently so I managed to get both sides of this story.

Essbase Visual Explorer is an OEM version of Tableau Desktop. In other words, it is the Tableau product rebranded as an Oracle Hyperion product.

The OEM agreement was originally made between Tableau and Hyperion. It made sense for Hyperion, because they did not want to invest in in-house development on any new front-ends, but they needed something to liven up their Essbase offering. It made sense for Tableau because they were a tiny unknown company at the time, and hooking up with Hyperion, then one of the largest BI companies, was a great way to push sales and raise visibility.

But Tableau has moved on since then. Hyperion’s unwillingness to market Essbase aggressively meant that Tableau could not depend on Hyperion forever, and Tableau now supports a wide variety of data sources. They said to me that they were “sunsetting” the relationship. My impression was that only a small proportion of their customers are Visual Explorer customers and they are ready to move on.

Oracle inherited the relationship from Hyperion, but its strategy has been quite different to (and in my opinion more sensible than) Hyperion’s. Reading between the lines of what Paul Rodwick said to me, my guess is that Oracle thinks that Tableau got more out of the deal than Hyperion did. Be that as it may, as a stand-alone tool Visual Explorer does not fit well into Oracle’s ambitious plans to integrate Essbase with its reporting and analysis suite, OBIEE. Visual Explorer is still on Oracle’s price list but the recently released BI Foundation Suite combining Essbase and OBIEE does not include Visual Explorer.

So Oracle will continue to support Visual Explorer, but both Oracle and Tableau have indicated to us that they have little interest in continuing the relationship, and I do not expect Oracle to continue actively positioning Essbase Visual Explorer in the coming years.

SAP raises the stakes with EPM 10

SAP is now adding new features to its (relatively) new integrated planning tool, BusinessObjects Planning and Consolidation, often still called BPC. It needs to show customers that it is up to more than just integrating its portfolio and it also needs to face up to scrappy new competitors like Tagetik and De facto, planning tools with a very similar architecture.

The presentation I saw yesterday was nominally about EPM, but SAP concentrated on Planning and Consulting (BPC). It has many new features including a new workspace and Web-based data input. This is something new since the original OutlookSoft product only allowed planning in Excel. Neither Tagetik nor De Facto offer this. The product also allows reporting on non-BPC BW data and a slicker looking Excel interface with some nice new features. Unfortunately, they couldn’t get the template function working in Excel for the demo.

SAP says they will gradually move the whole thing to HANA but did not provide details. Having the database in memory is the best way to provide the performance planners demand. However, in my opinion HANA’s architecture is not very well suited for planning. Column database architecture is available in other business intelligence tools such as QlikView and Microsoft PowerPivot, but they are not suited for planning.

Planning involves adding new data to the database (as opposed to overwriting data) and the automatic data driven modelling features of this kind of database makes it impractical to offer a simple way to add data. You cannot "discover" new periods, scenarios or products in an ETL process. Multi-dimensional databases, with their predefined dimensions, are better for this kind of feature, because the idea of an “empty cell” for adding new plan data comes so naturally.

How Information Builders gets around the Flash / HTML 5 controversy

As I mentioned in a previous post, the iPad is still a hot topic for business intelligence vendors, and both Oracle and Information Builders have just come out with new iPad support. At its Summit 2011, Information Builders has been demoing the InfoAssist tool with the built-in ability to switch between rendering in Flash and HTML5 on the fly.

Information Builders is not exactly a newcomer to the world of using HTML to render rich content. In fact the Information Builders Active reports were originally rendered in HTML 4 and offered an amazingly rich  user experience completely off line. But what was amazing back in the day is becoming more commonplace, with HTML5 making it much easier to build rich interactive content. This development shows that users and developers no longer have to takes sides in the Flash vs HTML 5 argument.

To me, the moral of the story is that Microsoft, Abode and Apple may well be wasting their time fighting over the rich web development platform. It was always pretty artificial. And it isn't just large vendors like Information Builders who have this kind of multi-platform capability any more. HTML 5 is not just for MP3 bloggers any more, and as cross-platform development specialists such as Appcelerator  and the many Flash / HTML 5 converters (including Adobe Wallaby) gain traction in the market, it is becoming less and less important to worry about the development tool used to get the content delivered.

The trouble with mobile user interfaces

Mobile user interfaces are a major trend in business intelligence. We read a constant stream of announcements by vendors about their support for mobile BI, even if the actual success stories are less common. I commented on business intelligence and the iPad here.

Timo Elliot made some interesting remarks about how mobile BI could have an affect beyond mobile, and this is my reply:

It should be pretty obvious to most people by this time that mobile user interfaces are going to play a major role in the future of computing. That is because the mobile user experience can never be reproduced. The question is how big a role.

But however big the role, this doesn't necessarily mean that graphic user interface design will be completely changed by mobile devices. Mobile interfaces aren't just new, they are also subject to completely different constraints than desktop systems are.

• Pointing with your finger can be seen as a much more natural user interface that using a mouse, but it is also less accurate.
• Simple interfaces fit small screens well, but the give users fewer clues as to what they can do next.

And so on. The user interface guidelines that have been developed for desktop systems still make sense, and as a result my guess is that mobile devices will not change desktop interface designs all that much.

SQL Crescent: A new step for Microsoft SQL

Crescent is the code name the new business intelligence user interface Microsoft intends to release with the Denali release of SQL Server. You may have heard about it, because Microsoft has been releasing excited videos about it, featuring huge crowds of developers going wild over the technology. I have not seen much of the technology itself, but what I have seen seems to borrow heavily on the user interfaces of Tableau and the Google Data Explorer.

The technology is closely related to PowerPivot. It is based on a new hybrid semantic layer that either directly access a data source or uses PowerPivot's Vertipaq column-oriented storage engine. It is part of Microsoft's not yet fully realized plan to provide seamless conversion of Excel-based data marts to a server environment.

To me, the most intriguing thing about SQL Crescent is that Microsoft's SQL development team is dipping its toe into the area of business intelligence front ends. (I don't really include Reporting Services because it is simply a reporting tool, not a specialized BI tool, and it works better with relational data than with multidimensional data.) In the past real analysis has been the domain of the Office group. PerformancePoint was a bit of a halfway house between the groups, but in the end it was folded into SharePoint, where the dashboard component still resides. Currently PowerPivot only has an Excel (or SharePoint Excel Services) user interface. So this seems like a big step.

The BI Survey has started

The BI Survey 10 has started! The world’s oldest and largest survey of users of business intelligence software is now online. Last year’s survey garnered over three thousand responses and could build on a data set stretching back to 2001 to analyze the trends in the market for business intelligence tools.

The BI Survey has always had the goal of shedding light on the real world issues that matter to users. It avoids the latest hype and buzzwords and focuses on costs, goal achievements and business benefits. It helps potential buyers avoid typical pitfalls of buying and implementing business intelligence software. The Survey also provides vendors with no-nonsense information on what buyers really need, not what they say they want.

This year the Survey sharpens its focus on the project. Business intelligence has changed as it has become more accepted, and more, larger vendors have entered the market. The year we pinpoint new issues:

• The size and scope of projects, and how these influence business benefits
• Finding the right product for a given project
• Who implements the project and how much it costs
• Business participation in product selection and implementation

The survey compares the leading products on the market across a number of headline criteria such as performance, scalability and vendor support. Also it is based on actual data instead of just educated guesses, which makes it a great resource for any company evaluating business intelligence products.

In-memory databases and mobile business intelligence

I was looking at some results of a benchmark test MicroStrategy did on its product. The benchmark was about supporting large numbers of users. MicroStrategy is pushing into the mobile business intelligence business and it has identified (correctly in my opinion) user scalability as one of the key challenges in this area.

Anyway, the benchmark tests to see how MicroStrategy would do with up to 100K users or so. Impressively, (if not surprisingly, considering they ran the tests themselves) the product did well. They ran the test both in Linux and Windows.

There were two things I found intriguing about the test: The hardware configuration of the application server, (144 GB of RAM), and the fact that they allowed the system four hours to load the data into cache, which is basically an in-memory cube.

In other words the Oracle database that was holding the data probably wasn't working very hard during the actual test. It worked during the four hours of loading, and was probably done for the day. Most of the heavy lifting was going on in MicroStrategy's in-memory database solution.

I think this is what we should expect more and more in the future: large scale database solutions of this type will make use of the falling RAM prices to squeeze better performance out of their solutions. Mobile applications with large numbers of users will need in-memory technology.

Flash and business intelligence

I have heard quite a bit recently about the demise of Adobe Flash. In fact I recently had a discussion with some programmer who were decidedly of the opinion that the future belongs to HTML5.

Apple does not like Flash, and has managed to keep it off the iPhone and iPad. Steve Jobs also claims that Flash is the most common cause for crashes on Macs.

Microsoft is not as strongly opposed to Flash as Apple is, but Silverlight is certainly intended to compete with it, and Microsoft has also thrown in support for HTML5, as as Google.

But I certainly don't see any move by business intelligence companies to move away from Flash in their reporting tools. In fact IBM Cognos released Cognos 10 fairly recently with more support for Flash than in previous versions. I also notice that Information Builders has actually more towards Flash in its Active Reports, away from the original DHTML version. And MicroStrategy doesn't seem likely to move away from its popular Flash dashboards, even if its current interest in mobile business intelligence will means more support for Apple platform.

I think people tend to underestimate the role that momentum plays in the IT business. I can understand the arguments that the markets are moving away from Flash, but I wouldn't expect it to disappear overnight.

Do companies really want transparency and collaboration?

Just finished our annual conference on planning tools. As usual, I talked to a lot of customers and vendors, and one theme came up several times: Some of the great features that vendors have on the roadmaps for their tools and that analyst list high in their discussions of trends for the new year may not be customer requirements at all.

I'm not talking about platform issues like mobile BI. This is about actual features of the tool. In particular, features that shed light on the thought processes that lead to the final planning numbers. Here are some specific remarks:

• Fine grained comments, for example comments on individual numbers, are rarely used.
• Detailed collaboration is often better done off line. Is this a tool issue or a cultural issue?
• Comments from large user groups tend to be too low in quality to be of much use.
• Middle management sometimes opposes processes that encourage transparency, even if they save time and effort.
• In some cases middle managers feel that storing data locally until it has been verified is better for them. So (to get back to a platform issue) Web-based data collection is not as popular as you might expect, a trend I have mentioned before.

Of course these are not universal truths. But it is interesting to hear how often they are mentioned.

Business intelligence and the iPad

I have been observing the wave of BI vendors coming out with applications for the iPad with some interest. QlikTech and MicroStrategy, who are always quick to move with the latest market trends, were among the first. IBM Cognos waited for their new release but also have a client as well. And with SAP having just spent billions on Sybase for its mobile technology, it’s not surprising to see SAP has also jumped into the fray with a new iPad client for Crystal Reports and the BusinessObjects Explorer – though not, as far as I know, using Sybase technology.

But the point here is not to list all the iPad BI clients available – I am sure I have missed a few. What interest me more is the question of how these interfaces are designed. The key to making a mobile reporting interface work is to squeeze interface onto a very small screen. There are lots of tricks for doing this, most of them involving navigations tricks with simple gestures to make traversing the interface feel natural.

But the iPad really does not have that small a screen. In fact, with a 9.7 inch diagonal, it is about the same size as an Asus Eee screen. It does not weigh a lot less either. But despite Eee’s success, business intelligence companies were not falling all over themselves to create a new interface of the Eee.

Furthermore, in my opinion, the interface that Apple gave the iPad is not quite appropriate. The first time I saw it I just thought, “Oh cool, it’s like the biggest iPhone ever”, and so did many other people, I suspect. But frankly, the iPhone interface does not expand all that well. In short, the iPhone interface is a good interface because it is visually attractive and it handles the severe size constraint it is subject to quite well. To make this possible, the users’ choices are intentionally limited, but users do not mind since the device is so small. But the IPad does not really have this constraint, and so the restrictions are more of an inconvenience. Furthermore, the bigger screen gives the user way of interacting with the software, so looking simple becomes more and more cryptic.

So iPad interfaces tend to discard the typical desktop standards that have been accepted over the decades (for better or worse) and replace them with a concept that is finely tuned for a completely different format. But most users – especially users of business tools as opposed to toys – are more interested in the content of the application than in fancy interaction techniques. Business intelligence vendors may be better off just making sure their Web applications work well on Safari running on the IPad than spending time developing iPad specific applications.
