Het vak van de Software Developer

Renaissance in Software Development

Programmer - an organism that turns coffee into software.

“ We are not laborers, we are not factory workers... We are professionals like doctors, like lawyers” Robert C. Martin

Agile manifesto Individuals and interactions over processes and tools Working software over comprehensive documentation Customer collaboration over contract negotiation Responding to change over following a plan Craftmanship over Execution

Manifesto for Software Craftsmanship Not only working software, but also well-crafted software Not only responding to change, but also steadily adding value Not only individuals and interactions, but also a community of professionals Not only customer collaboration, but also productive partnerships
