Why Business Processes Matter

Enterprise applications and information systems have became fundamental assets of companies. Companies rely on them to be able to perform business operations. Enterprise information systems can improve the efficiency of businesses through automation of business processes. The objective of almost every company is that the applications it uses should provide comprehensive support for business processes. This means that applications should align with business processes closely.

Although this requirement does not sound very difficult to fulfill, the real-world situation shows us a different picture. Business processes are usually of dynamic nature. Companies have to improve and modify, act in an agile manner, optimize and adapt business processes to their customers, and thus improve the responsiveness of the whole company. Every change and improvement in a business process has to be reflected in the applications that provide support for them. Only companies where applications can be quickly and efficiently adapted to the changing business needs can stay competitive on the global market.

We all know that changing and modifying applications is a difficult job, which requires time. This means that information systems cannot react instantly to changes in business processes—rather they require some time to implement, test, and deploy the modifications. This time is sometimes referred to as the information systems gap time. It is obvious that the information systems gap time should be as short as possible. However, in the real world this is again not always the case. Let us discuss the reasons.

The time required for modifying applications is related to several factors. The most important factor, in addition to the complexity and size of the modification, is the state of the application being modified. If an application has a well-defined architecture and has been constructed keeping in mind future modifications, then it will be easier to modify. However, each modification to the application makes its architecture less robust with respect to future changes. Applications that have been maintained for several years and have gone through many modifications usually do not provide robust architecture anymore (unless they have been refactored constantly). Modifying them is difficult, time consuming, and often results in unexpected errors.

The situation gets even more complicated. Several applications still in use in companies (particularly legacy applications) have not been developed with the objective of providing support for entire business processes. Such applications, often called stovepipe applications, provide support for certain functions or tasks only. For an information system to provide complete support for business processes, it has to be able to use the functionalities of several existing applications in a coordinated and integrated way. This makes the primary objective of information systems—to provide timely, complete, and easy modifiable support for business processes—even more difficult to achieve.
