Part 3: People and Process
People create code.
People follow a process when writing code - even if it is one of chaos.
Part three of this book discusses aspects relating to people, such as Software Craftsmanship and what makes programmers happy. Part three also looks at some processes related to software creation such as agile software development and pair programming.
At first glace some of these topics may not appear to be related to keeping software soft, but (for example) unhappy programmers may be more likely to write bad code and poor project management or time-management can create undue schedule pressure which leads to a temptation to write bad code.
