Compare the following procedure and process for making an omelette.
A procedure outlines a sequence of steps and says what should be done without reference to who performs individual steps; the process introduces the performers, who may be defined in terms of roles or individuals according to context.
This is part of a procedure for making an omelette,
Step 1: Open fridge
Step 2: Collect 1 dozen eggs
Step 3: Collect mixing bowl >=1L capacity
Step 4: Break eggs into bowl
Step 5: Beat eggs…
This is part of the omelette making process that implements the omelette-making procedure in the context of a small non-domestic kitchen with two staff roles, the Cook and the Kitchen Assistant.
Step 1: Kitchen Assistant opens fridge
Step 2: Kitchen Assistant collects 1 dozen eggs
Step 3: Kitchen Assistant collects mixing bowl >=1L capacity
Step 4: Kitchen Assistant gives bowl & eggs to Cook
Step 5: Cook breaks eggs into bowl
Step 6: Cook beats eggs…
Notice that Step 4 in the process is a new step that deals with a change in performer, which can only occur when performers have been specified. A process is therefore necessarily more detailed insofar as it must deal with changes of performer. The orchestration of a process therefore includes management of roles and individuals.
