CAPM Practice: Explain when it is appropriate to use a predictive, plan-based approach

Question 27 of 85 in Explain when it is appropriate to use a predictive, plan-based approach

Pick an answer below — you'll get the explanation instantly, no signup.

A project manager is asked to justify why she chose a predictive approach over an adaptive approach for a new office building construction project. Which argument is MOST compelling?
Show answer & explanation

Correct answer: Construction is sequential — you cannot install plumbing before framing — and requirements are defined in architectural drawings, making adaptive iteration impractical and costly

Explanation

The strongest argument is the physical constraint of sequential construction work combined with upfront requirement definition (architectural/engineering drawings). Physical construction cannot be 'iterated' the same way software can — you cannot build a different foundation in a two-week sprint and tear it down if the product owner changes requirements. These physical and contractual realities make predictive the natural choice.

**Why not B:** While predictive approaches do produce more documentation and are auditable, this is a secondary benefit, not the most compelling reason for choosing predictive over adaptive for construction. The physical constraints of sequential construction work and upfront requirement definition are far more fundamental arguments.

**Why not C:** Team preference is a secondary consideration that should not drive methodology selection. The physical nature of construction work (sequential dependencies, cannot iterate on foundations) is a far more compelling argument for predictive than team preference.

**Why not D:** The claim that adaptive approaches require co-located teams is not universally true, and large construction projects often have co-located teams anyway. This argument misrepresents adaptive approaches and fails to address the fundamental physical constraints that make predictive the natural fit.

Key Concept

This question covers Explain when it is appropriate to use a predictive, plan-based approach under Explain when it is appropriate to use a predictive, plan-based approach (Predictive, Plan-Based Methodologies).
