Processes grow over time and frequently become more complex and intertwined. Eventually people lose sight of why they are doing any particular process and what it provides to the final product.
NVP recently evaluated the processes for a service provider. An inventory of the existing processes was created and they were mapped to the business and technical requirements of the organisation.
We were able to eliminate many of the processes without any increase in risk to the project or the organisation.
Don't get caught in this!
Review your processes frequently.
