Criterion B: Developing Ideas

Criterion B: Developing Ideas

In this stage you will be expected to:

i.              develop design specifications, which clearly states the success criteria for the design 

of a solution. pages 1-2

-      The design specs should be measurable with a clear way on how the specs will 
be tested

Example: Game Product

Specification	Test
Game will be less than 1 MB in size	Install it in a computer  the size in properties
Played by two players (Multiplayer game)	Allow two players to play simultaneously
The game 3 levels that will advance in complexity.	Play the game at each level time the duration it takes to complete a level and record the complexities.

i) What is a design specification?

A specification is a set of constraints, requirements and considerations for a solution: what the solution must or must not have to be successful.

 A specification is not a description of the outcome. It should demonstrate that you understand the needs of the problem that you have identified. Every aspect of a specification must be specific, measurable, achievable, realistic and testable (SMART).

The specification should be directly connected to your design brief. Writing a specification can be a difficult job if the design brief is not well researched and written. If a solution or design fails to meet an aspect of the specification, it can be considered that it has not met the criteria for success.

You will need to refer back to your specification throughout the project, particularly when developing ideas and evaluating the solution.

The table below demonstrates poor and good examples of design specifications. Remember that these should be specific, measurable, achievable, realistic and testable.

Poor examples of a design specification	Good examples of a design specification
My storage device must look good/nice. The interface must look attractive	The storage device must contrast with the furnishings of the room; so bright colours such as red, yellow and orange would work really well. The interface must appeal to my target audience; whose favourite colours are hot pink and deep purple.
It must work well. It must function correctly.	The clock must display the time accurately.The clock must have a method to hang it on the wall. The storage device must store my jewellery collection (list the specific types of jewellery and quantity) 10 rings, 5 bracelets and 10 pendants.
My storage device must be the right size.	My storage device must be able to hold 20 pencils that are 170mm long and 8mm in diameter.The images on the web page must be clear and visible when viewing from 50cm from the screen.
My animation should be fun.	My Flash animation should contain animated graphics that carry the meaning of the song included, sing-along with bouncing dots and appropriate typography (Sassoon Primary or similar.)
My video must include music.	My video must include up-beat, hip-hop style music.
My video must not be too long.	My video must be last at least 1 minute and no more than 2 minutes.

                                                      

Changing specifications during a unit of work

You may have opportunities to develop your specification further as you continue through the unit of work.Changes in a specification should be justified through additional research that you may need to conduct as a result of finding that an aspect of a specification is not appropriate.

ii.            develop a range of feasible design ideas, which can be correctly interpreted by others
                pages 6-7

-      Develop a range of good quality designs and measure each of them against the 
design specs.

- Your description for each design should be detailed and clear and use captions 

on images or diagrams which are not clear.

Develops a range of feasible design ideas, using an appropriate medium(s) and detailed annotation, 

which can be correctly interpreted by others

Areas to consider:

• Draw/ sketch 4 designs.
• Annotate/Text/ explain every content placed on the storyboard.
• Leave a margin around the designs for easy scan or photocopy.
• Use black ink / dark pencil that are clear and readable.
• Show the direction of flow of ideas. use numbers, letters and arrows.
• Capture all the design specs.

By the end of year 5 students should be able to:

• develop and use a wide variety of techniques to generate a wide range of distinctly different designs through 2D and 3D modelling that are easily interpreted by others
• annotate designs with sufficient detail to explain how they meet the requirements of the design specification and to explain design thinking
• evaluate designs against the specification to identify the most feasible solutions
• develop the most feasible solutions to create a final design through modelling that fully meets the requirements of the design specification

For both digital and product design, a natural starting place when designing is with a pencil and sheet of paper, developing rough sketches of potential solutions. 

You should focus on getting the basic building blocks of ideas sketched out in short, concentrated bursts. 

These initial ideas should focus on generating a range of different solutions to the problem.

You should then identify which initial ideas should be developed further. This could be done through a range of strategies, including:

• further, more detailed sketches that start to develop ideas with direct reference to the specification
• detailed annotation that allows students to explore and communicate their own thinking through annotation
• making of simple card and CAD models and simulations used to test ideas and ensure they meet the specification.

Design idea development examples

The table below describes examples of strategies and techniques to communicate and develop ideas

Technique/strategy	Digital design	Product design
Initial concept sketching	Layout drawing Storyboard Scripts for audio	Two-dimensional sketches Three-dimensional sketches including perspective; crating; oblique, isometric and projection Rendering to show form, colour and texture
Development drawings	Detailed layout page design Visual mock-ups Web trees/maps Detailed audio script including directions on pitch, sounds, pause lengths, pace and music	Orthographic projection to scale Sectional views Exploded drawings Part and assembly drawings
Modelling	Mock-ups Prototypes Simulations	Card models Prototypes Three-dimensional CAD models

Communicating and developing ideas

What does it mean to develop an idea? How do I present this information?

Designers do not come up with a single, static idea that solves all aspects of a problem; designs are developed over time in an iterative fashion. You should record your iterative development through design sketching, modelling, refining and testing. This is all part of design development.

A range is not quantifiable. The number of ideas you create depends on the complexity of the problem, age, level of experience and time. When students ask how many ideas they should generate, the simple answer is: as many as it takes to solve the problem and to develop a design that meets all of the design specifications.

When developing your design ideas, you must always be working towards the goal of designing a solution to the problem, for which the requirements have been defined through the design specification. 

Therefore, you must work towards developing at least one design to meet the specification.
You should develop, or refine, every detail, including:

• the exact size and shape of individual components
• the required and/or available materials
• how the components fit together to create the whole
• the required and/or available tools and equipment
• aesthetics (colour, texture, shape, form, line, balance, finish)
• how the user will interact with the solution
• aspects relating to safety and accessibility.

What is a feasible idea?

A feasible idea is an idea you could successfully make independently in the given time, with your skills, and with the resources at your disposal.
You can include ideas in your design folio that do not achieve all specifications successfully, but these ideas should lead to feasible ideas through design development or be constructively criticized through annotation to highlight weaknesses and suggest improvements.
To ensure that ideas are feasible, they may need to be tested using mock-ups or models.

The following questions may help you reflect on your design ideas.

• Do I need to do more research to complete my design? For example, how do I join one part of my design to another?
• Does the school have the resources (tools, machinery, hardware, software or materials) to make the design?
• Do I have the skills to make this design? Can I gain the skills to make this design?
• Will I have to get any resources myself? If so, where and when?
• Will I be able to make this design in the time available?

Why is "annotation" important?

Annotation is vital for you to communicate the thinking behind your ideas and how that thinking develops. This is why annotation is so important. Simply sketching ideas will not clearly communicate them, as other people looking at these ideas may not interpret them correctly. 

Think about the following questions when writing your annotation.

• How did you come up with the idea? Did something influence your thinking?
• What materials do you think should be used, and why? Are the materials available?
• How could the idea be made? What tools, equipment and processes would you use?
• Could the design be made in the time available and with your skills?
• Would it cost too much?
• Is it safe?
• Do you think your client would like the idea?
• Why did you choose this colour/texture?

Other elements you should incorporate into your annotation include: how one idea led to another; how you could improve/develop your design ideas; whether you need to do more research, for example, into materials; and whether the client thinks your ideas are suitable.

Do all ideas need to be evaluated against the specification?

When designing, you need to develop your ideas towards meeting the design specification, resulting in your final design meeting the criteria. You should constantly consider the design specifications as you design and reflect this in your annotation. An evaluation of the final design against the specification should be included as part of the design’s selection.

Correct interpretation of design ideas

The correct interpretation of design ideas is vital for clear communication of ideas between a designer, client, target audience and manufacturer.
You are assessed on the quality of your design communication through strand 2, encompassing your sketching, modelling, refinement, development, testing and annotation of designs. If the teacher cannot determine or interpret the design, it is not sufficiently represented and the design thinking has not been clearly articulated.
You will need to combine your design sketching, mock-ups and models, CAD and annotation to clearly articulate your ideas.
