I will use the example of a standard custom cabinet production shop. Everyone can relate to a 600mm wide base cabinet with 2 doors. It is likely the most common unit to build and represents the standard product also. So, let’s call a 600mm base cabinet made with white melamine a standard unit of measure, or 1 SUM.
You can then gauge to a high degree of accuracy what every other cabinet type you build would be when measuring against 1 SUM. So, for e.g. a pantry may be 3 SUM, a 600mm 3 drawer base cabinet could be 2SUM. Corner cabinet could be 3 SUM and so on. It is VERY IMPORTANT to understand that this is NOT a 100% deadly accurate measurement but is a good overall average measure of your SUM production.
You can take this system and expand it to have factors for anything that is not while melamine. So, a painted SUM1 Base cabinet may take twice as long to be produced as white melamine, so you can factor it with a x2 factor. Go through all your possible options outside of while melamine and create factors for all of these.
**This is a very basic and simplistic explanation of how you can create a measure for your “SUM” in your cabinet shop and it can also be used to plan for capacity. For a full explanation please book a call with me to chat further.
When you sell a job, if you work through and determine the SUM size of the job, let’s say a kitchen you designed and sold adds up to 35 SUM, you can then look at what your total SUM capacity is per week or per month and plan your work at initial planning stage based on “will you be able to do the work or not” logic of capacity.
