27. Documentation • Chat contents • Minutes of meeting • Mail correspondence • Importance • The repository http://www.fer.hr/rasip/dsd/projects/8/docs

28. Hours spent in project-934 hs / 116 man days

29. Lessons learned • Communication is important and crucial- Never stop communicate- Documentation, requirements and design takes time- Tools for keeping track of project- Time consuming- A lot of learning and less output- We worked at 4 different locations- Used fer-homepage and CVS- Patience is important- Main objective is learned (teamwork in DSD)
