Exam CBAP topic 1 question 50 discussion

The approach Henry is using is C. Selective. In this scenario, Henry is prioritizing and selectively removing requirements to meet the predetermined budget. This means he's carefully selecting the features or components that stay within the budget, which is characteristic of a selective timeboxing or budgeting approach. He's not taking a "blanket" or "all-in" approach but rather removing specific requirements to make sure the project stays within the allocated budget of $450,000. Here's a breakdown of why the other options don't apply: A. Parametric: This method involves using historical data or models to estimate costs, but Henry is manually adjusting requirements based on the budget. B. All in: This approach would involve trying to include everything initially, but Henry is focusing on what can stay in the budget. D. All out: This would mean eliminating everything that doesn’t fit the budget, which doesn’t align with Henry’s selective removal process. So, Selective is the best fit.

Can someone please suggest if all the questions here are valid?

Henry is using a Selective approach to budgeting, where he evaluates each requirement individually and removes lower-priority or costly requirements to stay within the budget constraints. This aligns with the cost-benefit approach in business analysis.

Henry is actively choosing which requirements to include based on the budget constraint. He's not simply including everything (All in) or excluding everything (All out). He's making selections to fit within the $450,000 limit. This is the essence of a selective approach to budgeting and timeboxing.

Henry is using the Selective approach to timeboxing and budgeting. In this approach, the business analyst prioritizes requirements by evaluating their costs and removing less critical or lower-priority requirements until the project fits within the allocated budget or time constraints. This ensures that the most valuable and essential requirements are included while staying within the budget limit of $450,000.

All in - Option B

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

BABOK v2

Parametric is an element under Estimation. This is talking about prioritization where timeboxing is listed in BABOK v3 pg. 313

A: BABOK v3 pg 272

The other approaches are not in the BABOK v3

Babok v3 pg 272, Parametric is the only approach defined in the book.
