Part A of this report, an “Initial Investigation” is to be submitted at the end of Week 6 (Friday 7th December 2018). The final report (including your Part A adjusted after marker feedback) is to be submitted end of Week 12 (Friday 8th February 2019). You should use all relevant parts of the case study to inform your answers for the report. Additional information will become available through session which you may use to “enhance” your analysis and design but you should maintain a focus on your original scoping.
