THE DESIGN PROCESS

DESIGN PROCESS Learning Outcome Number 2 - DESIGN PROCESS Learning Outcome Number 2 - It constitutes 20% of the NCS learning outcomes. - It is the application of the 3 Learning Outcomes. HOW DO WE KNOW THAT THIS OUTCOME IS ACHIEVED? We know this when a learner is able to understand and apply The Design Process within the CIVIL, ELECTRICAL & MECHANICAL context.

THE PROCESSES OF THE DESIGN PROCESS The following steps need to be followed when drawing up a design process. Identification of the problem Investigation of the problem Design Make Evaluate INVESTIGATION 2 5 1 DESIGN EVALUATE PROBLEM 3 4 MAKE

Out of this we will choose the suitable process The Design Process can be represented in many forms diagrammatically. Linear & Cyclical: It can be as simple as the four basic steps. It can be extended to interaction between the steps. Or it often happens that a previous step must be repeated. Or the process must be approached from a different point of view from within the process. Or it also can be that a step is integrated with the previous step as well as the next step. Out of this we will choose the suitable process The Linear process can well be applied to lower grades where critical self-evaluation can not yet be applied so effectively by learners. The Cyclical process can be use in higher grades were more critical self-evaluation and cognitive actions can be expected from learners.

Examples of Linear 2 Situation in context Investigation 1 Investigate Design Design Develop/make Make/develop Test and evaluate Evaluate Products & systems

Describe the problem clearly 1 Describe the problem clearly What made me aware of the problem ? What are the implications ? A statement describing the problem gives you a way of thinking about the problem in a clear way.

Describe the desired results 2 Describe the desired results What is the expected situation (standard)? What is the desired situation (outcome)? What are the difference between the present situation and the desired one?

Implement the solution 3 Clear and planned actions are put into practice. Trying out the most highly ranked solution (alternative)

Gather Information (Investigation) 4 Gather Information (Investigation) Conducting basic research (conducting interviews). Conducting case studies. Collecting of the conditions under investigation.

Thinking of alternative solutions 5 Thinking of alternative solutions Each participant is given an opportunity to put forward an idea’s (brainstorming). Group together possible combinations. Using different ways/actions in trying to solve a problem (trail and error)

Choose the best Solutions 6 Choose the best Solutions Each solution is examined to see how far it brings us to the desired situation. Testing resources each solution may require. Ranking solutions, say up to three.

Look back at the solution and make necessary changes 7 Monitoring how well an implemented solution brings you closer to the desired results. Once satisfied with the results, a full-scale implementation can be considered. If necessary, we can make changes to the solution.
