Henry is the business analyst for his organization. Management has created a pre-determined budget of $450,000 for his solution. Henry has identified the project requirements but now wants to prioritize them based on timeboxing and budgeting. Henry examines the cost of the requirements and begins removing the requirements from the allowed list in order to meet the $450,000 budget.
What timeboxing or budgeting approach is Henry using?
Henry is using a selective approach. This is evident as he examines the cost of the requirements and begins removing some to meet the predetermined budget of $450,000. This method involves selecting and prioritizing requirements based on given constraints, in this case, the budget.
Parametric is an element under Estimation. This is talking about prioritization where timeboxing is listed in BABOK v3 pg. 313
Babok v3 pg 272, Parametric is the only approach defined in the book.
Others do not exist in the babok
The other approaches are not in the BABOK v3
All In – You start by including all the requirements necessary for the solution to be developed and then remove/postpone the requirements whose implementation will cause the project to exceed the deadline.
I think that it's Selectable as based on the allocated budgeted , certain requirements have been selected to move one. It wasn't mentioned that the least expensive will be selected , or most expensive ones. Therefore it's selective , not based only on the budget but other parameters' like requirements dependencies
