Say goodbye to complicated interfaces, disconnected analytics and shelfware. An emerging era for BI will bring simplicity, broad access and better ties between analysis and action. By Neil Raden 1, 2007 Why do three billion people a day use a Web site that has a Spartan interface, a weird name (Google) and the capacity to do only one thing (the original search engine, that is, not the newer applications)? Perhaps the reason is that it always gives you more than you asked for, but what you want is usually on the first page. No one needs to install software, to do upgrades or, for that matter, to pay for it. And no one needs a training class. Contrast this with Business Intelligence (BI) tools today, with complicated interfaces, software that is very expensive to purchase and maintain, and version upgrades that are often painful. These tools generally offer very broad functionality, but somehow it's never quite enough to solve the problem. There are, at best, a few million copies licensed worldwide (across all BI vendors), yet more than a third of these seats are shelfware, according Optima Publishing's OLAP Survey 4. One could argue that phenomenon of the Web is so unique that it is unfair to measure BI's performance against it. The problem is that this is the second time BI has been eclipsed by another technology, as proven by the fact that there are more than 200 million licensed copies of Microsoft Excel in use today. Rest assured, the current era of BI is coming to an end and will be succeeded by a BI 2.0 era that promises simplicity, universal access, real-time insight, collaboration, operational intelligence, connected services and a level of information abstraction that supports far greater agility and speed of analysis. The motivation for this \"version upgrade\" for BI is the need to move analytical intelligence into operations and to shrink the gap between analysis and action. BI 1.0 Defined Despite its drawbacks, BI is not a failure. In most ways, the facility for getting information to people where and when they need it is dramatically better than it was more than a decade ago, when reports were usually paper-based and required months of development to line up the data. But if you boil BI down to its basics, it is derived from only two things: data and reports. Most of the effort in BI in the last decade has been focused on the data issue \" data integration, data quality, data cleansing, data warehouse, data mart, data modeling, data governance, data stewardship. BI tools are dependent on these efforts. Existing BI solutions are designed primarily for people who can understand the data models and who have time to build analyses from them, recall them for future use and provide information for others. Within most organizations, these experts account for about 5 percent of the salaried workforce. That was fine for a decade or so while we worked out the problems and fine-tuned the architectures and methodologies, but the people who are supposed to be served by this effort have largely voted with their feet and marched back to shadow systems, particularly spreadsheets, where the bulk of analytical work still takes place. While the number of BI users is increasing, the bulk of the increase is in passive report distribution, not active analysis, collaboration or decision-making. Along with data, reporting drives BI. What is a report? At the simplest level, a report is the rendering of information requested from existing data, with at least some level of formatting and usually some added calculations, such as subtotals and totals at a minimum. Reports are read-only. Originally, reports were distributed on either paper or microfiche, but about 25 years ago it became possible to see them electronically. Today, they can be delivered to the Web, to portals, to cell phones, PDAs -- just about anywhere. Making reports \"interactive\" doesn't really change their nature. The ability to select parameters, for instance, is actually a reporting application surrounding just another report. The ability to navigate through the elements of the data model interactively, such as OLAP, ultimately ends up as the visual display of just another report. No matter how many ways the fetching and formatting of data is embellished, it is still a report. Some OLAP tools are not read-only, but their use represents a tiny fraction of the BI use which, in turn, is an almost imperceptible fraction of the daily use of alternatives, especially spreadsheets. BI 2.0: What to Expect The new era of BI, which is already here, goes far beyond data and reporting. BI is becoming proactive, real-time, operational, integrated with business processes, and extending beyond the boundaries of the organization. To become pervasive and grow out of its reporting niche, BI has to provide simple, personal analytical tools on an as-needed basis with a minimal footprint and cost. Rather than relying solely on a rigid metaphor like data warehousing, BI needs the ability to access data anywhere it can be found and to performing integration on the fly, if necessary. Locating the right information to solve problems must be a semantic process, not requiring knowledge of data structures or canonical forms. Directed search, based on the meanings of and relationships among objects, allows practically any person or service to find what is needed without assistance, whether it is structured information like relational databases, message queues, logs, web services or even unstructured content. The Web was not just a brilliant idea, it was and is a world-changing phenomenon. Yet even in light of this success, it is quickly moving to an entirely new plane of existence, one that is more collaborative, intelligent, rich, semantically aware and simple. Web 2.0 is about closing the loop, from being a collection of web pages to a being the single platform for just about everything. The physical resources are in place and attractively priced, the open standards are evolving without fracturing the confederacy of technology players, large and small. The missing piece is the semantic technology, but even that is progressing nicely as semantics pure plays are gobbled up by more well-heeled operations like IBM, Google and webMethods. BI needs a 2.0 initiative too. BI 2.0 won't replace BI, it will extend it. Current BI capabilities are well-suited to many tasks, such as individualized dashboards of overnight data or providing a rich environment for interactive exploring of data, by people and by algorithms. But current BI practices have always been weak dealing with the unexpected and the urgent because of their \"data first\" orientation. Spreadsheets shine here, but they lack too many architectural prerequisites to be useful, such as collaboration, security, abstraction and versioning, among others. If spreadsheet tools develop these characteristics, and they are heading in that direction, they will not usurp BI, they will become BI. Game Changers BI 2.0 will disrupt the BI industry in quite a few ways, and foot-dragging can be expected. Some more obvious effects will be:
BI 1.0 Fallacies | BI 2.0 Realities |
Most users want to be spoon-fed information and will never take the initiative to create their own environment or investigate the best way to get the answers they need. | The Consumer Web invalidates this idea. When given simple tools to do something that is important and/or useful to them, people find a way to \"mash up\" what they need. |
Vendors will obfuscate and slow down the drive for simpler and more affordable tools to preserve their bases | They will, but demographics will pressure them. Most BI \"users\" will be members of a generation that lives in technology and will reject the functionality of current BI |
Only air traffic controllers and credit card approval applications need real-time data | The availability of fresh data, from ever-widening sources, generates its own demand |
Analytics cannot be supported until there is an enterprise data warehouse, with a metadata repository, data stewards and a comprehensive data model that represents the \"single version of the truth.\" | Data comprehension will displace data warehousing, to some extent. The single version of the truth will give way to context, contingency and the need to relate information quickly from many sources |
Operational systems cannot be queried for analytics | There is no longer a good reason for this prohibition. In fact, with SOA, it doesn't even make sense. |
Data must exist in a persistent data store for analytics | Message queues, logs, sensors \" transient data and caches, temporary aggregates, lingering partial results files \" all of these can be leveraged now with the resources at hand. |
