3. All of the above calculations contribute to the overall cost of the product, everything is included to get an accurate cost to ensure it would be worth manufacturing.

4. Total Costing Using all the information from each table, the total cost to manufacture the product was calculated. This is how much the product would cost to manufacture in total including costs of staff, rent, power, water and materials etc. £132.19 is quite expensive but existing diabetic products range between £50 - £150. The fact that a few parts were bought in added to the total cost quite significantly so if these parts were re-designed and altered slightly this would reduce the cost.

5. TEST PLAN Blood Glucose watch

6. User - The product would be more aesthetically pleasing, by experimenting more with various colours to make it more unique to different diabetic products -The product wouldn't be as bulky and be more discreet on the users wrist. -As the product is quite expensive, a survey would be completed to see how much people would be willing to pay if they thought it could help them manage their condition more efficiently. -I would get a variety of different people to wear the prototype, and make them take part in activities to see if the product will actually make it easier to test blood sugar when on the go. Product evaluated against PDS 1.1 Product must be able to allow user to test blood glucose, or show how it would work The prototype and previous work explains how the product would work but to test this I would ask people to wear it and see if the find it easy to use as this is the key feature. 1.2 Must allow blood testing be less time consuming than existing products A test would have to be completed with a working prototype but this should be a key feature. 4.2 Must remain comfortable on the wrist after several hours of use I would create a test where several people would wear the prototype for several hours and then complete a questionnaire about their comfort during the test, and possibly change the design depending on the result. 2.2 It will be aesthetically pleasing so user enjoys wearing it (looks like a normal wrist watch) More tests would be completed on the strap of the watch to ensure it’s aesthetical and functional to fit any individual user.

7. Safety - Product will comply with all EU regulations regarding extra-low voltage, electrical devices and accessories. -All parts will be assembled securely, this will be checked by completing several quality control checks throughout the assembly and production. -All of the electronic parts will not overheat causing high temperatures which could harm the user. Life and Reliability - It would be made certain that the product would last at the very least a year with frequent use as the user will become dependent on the product to manage their condition. -Parts will be disposed of correctly when the product has finished its life cycle. -The battery should allow the watch to operate successfully with frequent. Packaging -There will be no sharp edges on the packaging of the product -It will be a simple geometric shape to allow a mass amount to be transported and displayed properly. -It will be made from strong material to withstand damage. Standards -16.1 BS 7671 - Requirements for electrical installations -BS EN ISO 15197 - is the Standard that specifies requirements for in vitro glucose monitoring systems that measure glucose concentrations in capillary blood samples and procedures for the verification and the validation of performance by the intended users. These systems are intended for self-testing by laypersons for management of diabetes mellitus. -BS EN 61709:2011 - Electric components. Reliability. Reference conditions for failure rates and stress models for conversion -BS 8887-2:2009 - Design for manufacture, assembly, disassembly
