Power Point presentation of adequate length to explain the problem, solution, and evaluation of the solution. Do not simply repeat the material in the written report and avoid too much detail but assume this is the key feature of your explanation of what your team has developed to solve the problem. The management team of your contracting business will watch your presentation and use the written report for back-up details as desired. Much of their decision on the project will be based on this presentation and how effectively you sell your solution.
I can design the slides I just need outline and notes for speaking like a presentation
