Read the work that is done by this week and write a lessons learned

Projects are certainly learning organizations! This term we will experience lessons learned from both our applications of project management and our team interactions during the development of our Capstone project.  During a project, it is a best practice to learn from these experiences and continue to improve on the project and how we are completing it based on what is and is not working. 
As a result of each two-week session, the project manager will conduct a lessons learned with the team and post a short paragraph to share what is and isn’t working around both the content of project management and the process of the team.  (One of my tricks is to always phrase posted lessons learned to the positive – it is easier to share what TO DO versus what not to do).  What should you as a team keep doing?  Or stop doing?  Or start doing?  From a project management content perspective, what tools/techniques are valuable?  What can be done differently?
