The technologies and processes that help us deliver BI services have advanced by leaps and bounds over the last two decades. A modern BI program provides three perspectives on business performance, roughly corresponding to the past, present, and future.
OLAP and Reporting
OLAP and reporting services (or simply "OLAP") provide the "official record" of what has happened in the past--the canonical log of business activity.
This pillar of the modern BI program helps the business understand "where we've been." The typical information products provided in this service area include:
- Reports provide pre-built, parameterized access to business information
- Analysis provides the ability to explore the official record of business activity by slicing, dicing, drilling, and so forth (OLAP)
- Ad hoc query capabilities allow people to ask their own questions about the official record, even if a pre-defined report or analysis does not exist.
For people in the business, these kinds of information products come to define this pillar of the BI program. There is also a fourth important information product of which the business may have less direct awareness:
- The integrated record of business activities, aka "Data Marts." This record combines, standardizes and organizes information for business consumption.
Essential in delivering the first three kinds of information products, this component was the primary focus in the early years of BI, when we called the practice "data warehousing." Since then, the discipline has changed and expanded. But it is still essential that the BI program provide the ability to understand the past.
Performance management services provide real-time status on key performance indicators, as well as performance versus goals.
KPI's and goals are carefully matched to the viewer's role and linked to business objectives. Goals communicate expectations, while KPI's communicate achievement of expectations.
If OLAP is about "where we have been," then performance management is about "where we are now." Typical information products in this BI service area include:
- Dashboards provide real-time or near-real-time status of KPI's
- Scorecards which communicate progress vs. goals
Information on dashboards and scorecards is carefully tailored for the user or functional area. Metrics are chosen for relevance and actionability, linked to business strategy, and balanced to reflect a holistic picture of performance.
While this service area can stand on its own, performance management solutions are more powerful when people can dig into the KPI's on their dashboards. This capability is enabled by integrating performance management services with OLAP services.
Analytic services probe deeply into data, providing insight into cause and effect, making predictions about what will happen in the future, and prescribing a course of action.
While analytic services draw on data from the past, their objective is to influence the future. Typical information products in this service area include:
- Analytic models that make sense of activities or predict future events
- Simulations that allow the manipulation of variables to study their potential impact on results
- Visualizations that communicate analytic insights
- Analytic metrics that assess current state and or future outcomes which are fed to OLAP, performance management, and OLTP applications
Like the other pillars of modern BI, analytic services can exist alone but are more powerful in the presence of the other pillars. Prescriptive metrics, for example, are best presented directly on operational dashboards; useful analytic metrics can be recorded and tracked over time in data marts.
Delivering Modern BIIn each area of the business, these capabilities should be balanced and tied together. Centralized management of all three pillars is not required, but they should be coordinated and integrated. A shared roadmap should lay out their planned evolution.
Your objective is business impact, and my next post shows how these services deliver it.
