You are to select one project for development from the three options identified in task 1 using decision making software such as Mindgenius and devising a selection matrix. Your selection matrix may include parameters such as cost, availability of components, timescales, fit for purpose etc.

three options: ➢ Read Tooley and Dingle’s BTEC National Engineering (2nd Ed.) 2007, Unit 3 pp191-242

This is level 3 but a useful read.
