However I don't think this is the key point about agile
methods. Lack of documentation is a symptom of two much deeper
differences:
Agile methods are adaptive rather than predictive.
Engineering methods tend to try to plan out a large part of the software
process in great detail for a long span of time, this works well until
things change. So their nature is to resist change. The agile methods,
however, welcome change. They try to be processes that adapt and
thrive on change, even to the point of changing themselves.
Agile methods are people-oriented rather than
process-oriented. The goal of engineering methods is to define a
process that will work well whoever happens to be using it. Agile
methods assert that no process will ever make up the skill of the
development team, so the role of a process is to support the
development team in their work.In the following sections I'll explore these differences in
more detail, so that you can understand what an adaptive and
people-centered process is like, its benefits and drawbacks, and
whether it's something you should use: either as a developer or
customer of software.
- First, event management is primarily about the identification and generation of business events from the ambient events. Similar to what Carole-Ann and I had written in previous posts.- Second, IBM wants to introduce high level EPLs to express the logic for that processing that are business-centric, something very similar to what Business Rules Languages and approaches are in the business rules management area.
- leave anything related to transport, communication to other layers- use this revised CEP to express and execute event-relevant logic, the purpose of which is to translate the ambient events into relevant business events- have these business events trigger business processes (however lightweight you want to make them)- have these business processes invoke decision services implemented through decision management to decide what they should be doing at every step- have the business processes invoke action services to execute the actions decided by the decision services- all the while generating business events or ambient events- etc.
