I am currently working as software developer in a medical device project. The project is – as usual for projects of large scale – late in time and over budget. So the decision was taken to add more developers, reminding me of Brook’s Law:
Adding manpower to a late software project makes it later.
_Frederick P. Brooks, The Mythical Man Month, Addison-Wesley, 1995_
The other decision was to use agile software development methods.
