|Would this sandwich meet the brief?|
Well surprisingly NBS does not have template specification clauses or detailed technical guidance for sandwich specification. But considering something as simple as a sandwich illustrates some interesting specification principles. Also, if something as simple as a sandwich is quite involved and makes you think - then imagine specifying a curtain wall or air conditioning system?
So - consider a sandwich... (and if you could avoid the pun - please take this with a pinch of salt*)
Figure 1 below shows that the brief for the sandwich has been brought through digitally to help the specifier. An excellent specification template set of clause items exists that allows the specifier to select different structures of sandwich. Is this an open top, a standard two slice or even a double decker sandwich? The "Middle layer" is being removed in the example below as the brief clearly states that this is a standard sandwich.

|Fig. 2 Selecting the products|
As each selection is made, then the corresponding product clause is brought into the specification. This check box/additive way of working means that clauses that are not required (say a clause specifying a slice of beef) are not accidentally left in the specification by mistake.

|Fig 5 - generic vs proprietary specification of products|
|Fig 6 - Specify the workmanship|
|This sandwich definitely doesn't|
meet the brief.
