Processes, procedures and comportments have to proof their value to the business.
Formality may have its benefits, but they have to be made explicit and the value has to be bullet proof. The costs of formality like decreased agility, flexibility, poor customer service, hidden costs etc have to be brought on the table.
Two points to start with are possible:
a) Each element of formality has to be evaluated. Where is the benefit? Does it lower costs, does it increase speed? Does it increase quality or any other metric and if yes to which degree?
b) Start from scratch. What is a minimum set of formality the enterprise needs at least.
Then we have to look at the alternatives any less rigid procedure or rule or process should be preferred. These alternatives can be variations of the existing formality, but with more flexibility and agility.
