There are five major stakeholder areas :
Both Agile and Lean tell us to break the traditional approach of contacting the stakeholders at a specific moment of the project development, and instead keep a permanent contact with them throughout the project development.
This chapter of the book talks about the people involved in the system development and the processes that guide their work:
As there is a lot to cover in this chapter, I will make several posts to cover it in small batches.
In this post, I will write about the value stream.
Chapter two of the book is a small preview of the whole book, where the authors talk a bit about:
An application is made of several components and sub-components, all of which are essential to the functioning of the application. However, there are components more important than others. Continue reading “PPPDDD.3 – Focusing on the Core Domain”
Recently I revisited this conference talk Uncle Bob gave about functions/methods, where he gives us a set of guidelines on how to do them clean. These are the main guidelines I gathered: Continue reading “Clean Code 3: Functions by Robert C. Martin (Uncle Bob)”
Distilling the problem domain is about understanding the problem and its domain in order to uncover what is relevant and create a model that reflects the domain and solves the problem at hand. In DDD, the activity of doing this is called in Knowledge Crunching. Continue reading “PPPDDD.2 – Distilling the Problem Domain”
Building software that works is not difficult.
What is indeed difficult is to build software that lasts for many years, that keeps working despite the changes needed by the business, needed by the users, needed by new technologies. Building software that is permanently ready for change, and permanently and accurately reflects the business… thats the tricky part. Continue reading “PPPDDD.1 – What is Domain Driven Design?”
I find the reading of pattern description to be tedious, and the whole part 2 of the book, from chapter 9 to 18, is a listing of design patterns. Therefore I will simply list them with their one sentence description. Continue reading “PEAA – Part 2 – The patterns”
This chapter is a bit more than a revision to the previous chapters. Much of what Fowler states, is outdated. Many of the questions he had at the time are not questions any more, they are certainties, some were even trendy and are currently outdated.
In any case, mixing his view at the time with my understanding of what is common practice now days, this is what I take out of this chapter. Continue reading “PEAA.8 – Putting it all together”
This chapter talks about options to build a distributed system. However it is extremely outdated, as an example I quote ” SOAP is probably going to be the most common form…”. It turns out that the SOAP golden days were not there yet and currently have already passed. Now days most distributed systems are doing Microservices through RESTfull interfaces.
