1. BTEC IT Unit 02 - Lesson 10Stand Alone System Performance Mr C Johnston ICT Teacher www.computechedu.co.uk

2. Session Objectives • Know different criteria which can be used to evaluate a stand alone computer which has been setup for a user.

3. Evaluation Criteria • After you have installed, configured and tested a system for a client or user you should reflect upon its performance in meeting the user needs, • Key questions need to be answered within your reflection: • How well does the system work? – analysis of your testing • Is the operating system setup correctly? • Are the correct device drivers installed? • Do the software applications open and work as intended? • Is the system configured correctly i.e. • Are the default folder settings correct? • Do the desktop shortcuts go to the right place? • Do the menu options work as intended? • Is the correct date and time set? • Does the system fulfil each the user requirements defined earlier within the course

4. Improvements • Once you have evaluated the performance of your system to get D2 you need to explain and justify improvements to it, • Based on your findings in M3 you need to explain how the system can be improved to meet the needs more closely, • Changes could be new hardware, new peripherals, new software etc. • The changes need to be justified in terms of: • How much the improvements are going to cost – are the potential gains worth it?? • The potential gain the user will receive – do the changes actually meet the needs closer or are they a waste??

5. Task 2 – Part D [M3] [D2] • This task requires you to write a report which evaluates how well the stand alone system you setup, configured and tested in P5, P6 and P7 works and meets the requirements of your client, • You need to first of all evaluate the system in terms of how well it works – what went well in testing? what failed? Use the questions on the previous slide to help, • Next you need to list the user requirements of the system and state how well these needs have been met or in some cases not, • Finally explain how the system could be improved to meet the users needs more closely – remember to justify all changes in terms of cost and potential benefit • Some improvements may not be worth it – still mention but conclude that they are not worth it.

6. M3 – Evaluate the performance of a computer system. D2 –Explain and justify improvements that could be made to a computer system. • M3 is an extension of P7. You should gauge system performance in your tests and evaluating the data. • For D2, you should offer suggestions on how the system could be improved, considering costs involved and potential benefits gained. • Evaluation of System Performance [M3], [D2] • Analysis of Testing • Dsd • Sds • Sds • Analysis of Meeting User Requirements • Dsd • Sds ] ] [ [ Evaluation based on all the bullets under red bullet point 1 on slide 3 List each user requirement and evaluate How well you have met / not met it [ ] Suggest how each user needs could be met more closely… need to explain the costs and benefits from each suggestion and justify if its worth it or not
