Designing ICT solutions must be approached on two levels. First, business processes must be understood, optimized, and documented, and second, technology solutions can then be designed to support the optimized business processes. In this chapter, methods for documenting business processes are introduced. The goal is to create process documents that show how ICT will be implemented to improve or innovate business tasks. Documentation may seem to be one of the most boring and thankless jobs, but it is one of the most critical. The documents produced must be appropriate for management to understand the business processes, so engineers can build the recommended infrastructure, and for users to comprehend the purpose of the ICT being built.
