Constraints

 Constraints

Constraints are the limits set out in the brief which you must work under. Failure to do will

result in a loss of marks! 

The best way to approach this is to treat constraints under 2 headings:

• Hard Constraints
• Soft Constraints
  

Hard Constraints

Hard Constraints are those stated in the breif.

For example:

• "All main operating features must be clearly visible without dismantling".
  

• "The longest dimension must not exceed 300mm"

• "Electric Power does not exceed 9Volts"

Soft Constraints: 

Soft Constraints are not stated in the brief but they are (hidden) constraints you need to be aware of.

• Time: find out the specific deadlines that you will need to have the project made by.
  

• Cost? Calculate what the project may cost
  

• Materials Availability? Investigate or ask your teacher what materials are available to you.
  

• Skills and tools needed? Have you access to all the tools needed? Can you perform the skills required?
