In the current frantic push of enterprises to digitize their operations, in the form of digital transformation, there is one old process they can't get away from and that's Business Process Reenginering (BPR).
BPR has been around forever, but really came into prominence during the heyday of big ERP (Enterprise Resource Planning) implementations in the 80s and 90s. Those implementations were very difficult and costly and it soon became obvious that BPR was necessary in order to fit the technology and the business together and at the same time make best use of the technology to optimize the business.
Now, the situation of ERP systems is very different. They are well established in, and in many cases, central to the processes of the business. Where once they were the disruptive technology, now they are the legacy systems. Many companies are moving them to the cloud.
Cloud based ERP systems are different from those legacy ERP systems. Partly because ERP has evolved in recent years, and partly because of having transformed to cloud applications, which require new and different operational and security processes.
In the process of digital transformation, many organizations are now using DevOps, which involve automating the processes of software development and IT teams. Since the IT teams must necessarily be concerned with BRP, the DevOps processes must be consistent with the BRP efforts, particularly where they meet.
All of this means that digital transformation can be a tremendously complex affair.
