I have a problem I can't workout.
I have 3 work streams
maintenance optimisation innovation
I know I'm going to spend $20\%$ of my time on maintenance but don't have any specifics line items I know I will spend $4$ units of time work on optimisation and $2$ units work on innovation.
Is there a way to work out what percentage of work I will do on Optimisation and Innovation?
to clarify M + O + I = 100% M = 20%
so O + I = 80% O=? and I =?
