3. Create - (iv) Fully justify changes made to the chosen design and plan when making the solution
At the end of year 5 you should be able to:
- justify, through the use of drawings/diagrams, any changes made to the design while making the solution and how they affected the plan
As you implement your plans, you will often come to a point where you will have to modify the plan or the design. You will need to ensure that you detail and justify any changes that you make during the creation process.
If you do not make any changes to your product or plan, this strand does not have to be addressed with evidence. However, if any changes are made, you must address this strand.
Example
There are two main changes and modifications I have made to my original idea:
Modification to my Design
Now that I have made a plan to follow and thought about all the materials, tools I am going to use and how much time the project is going to take, some features of my design changed.

Example
There are two main changes and modifications I have made to my original idea:
- The hole on the edge of the small wooden pieces (used for the numbers) used to help lift the pieces was originally a square of dimensions 15mm x15mm. Nevertheless, I have found a better solution that is easier to create and is more practical. I will instead create a circle of radius 10mm. This will be done using a bench drill which is easier and faster than cutting it in a square shape using a saw, especially since I will be creating 20 pieces of these.
- In the original plan, the snake was supposed to be painted on the top 600 x 420mm wooden piece, with the holes for the number pieces being in it. Nevertheless, I have found a better solution which is to cut out the snake (with the dimensions listed in the ‘Parts list’ page) and create the holes in the snake itself. This would not only make the product more attractive, it would additionally make its creation more practical and easier since it would be easier to rotate the snake than the whole board when creating the holes.
Modification to my Design
Now that I have made a plan to follow and thought about all the materials, tools I am going to use and how much time the project is going to take, some features of my design changed.
- To start with, I changed the thickness of the circle of the sun which is where I am going to locate the clock mechanism. This is because the part of the clock mechanism that has to be drilled through the material is 6cm long. So, it is going to take a long time to drill a whole about 14cm deep on an 18cm thick material. I thought it would take less time drilling a whole about 2 cm deep on an 8cm thick material
- Now that I thought about how long it is going to take to create stickers, I decided make more Number Stickers. Before I made the plan, I thought it would take the longest time to create the stickers on the vinyl cutter; however, I realized it actually doesn’t. I was going to only make four stickers: 12, 3, 6 and 9. But, since it doesn’t take so much time creating them, I decided to make all twelve stickers. I also realized that while I am waiting for the stickers to be cut out by the vinyl cutter, I could be using the time and start working on the next step which is putting the clock mechanism on to the clock design.
- The last change I have made is to use spray paint for one or two parts. If I use paint, I have to paint several coats and dry them. Same goes for spray paint; however, if you compare the time on how long it takes to paint and spray a material once, to spray paint takes less time.
