SPaMCAST 295 - TDD, Software Sensei, Cognitive Load

SPaMCAST 295 features our essay on Test Driven Development (TDD). TDD is an approach to development in which you write a test that proves the piece of work you are working on, and then write the code required to pass the test. You then refactor that code to eliminate duplication and any overlap, then repeat until all of the work is completed. Philosophically, Agile practitioners see TDD as a tool either to improve requirements and design (specification) or to improve the quality of the code.  This is similar to the distinction between verification (are you doing the right thing) and validation (are you doing the thing right). We also have a new entry from the Software Sensei, Kim Pries. Kim addresses cognitive load theory.  Cognitive load theory helps explain how learning and change occur at personnel, team and organizational levels. Next week we will feature our interview with Jeff Dalton. Jeff and I talked about making Agile resilient.  Jeff posits that the CMMI can be used to strengthen and reinforce Agile. This is an important interview for organizations that are considering scaled Agile frameworks.
