Which statement is TRUE with regard to technical stages?

Technical stages describe the grouping of work based on the specialist skills required to create products (e.g., a design stage, a build stage, a testing stage). Unlike management stages, which are sequential and serve as control points for the Project Board, technical stages can be organized in any way that is logical for the specialist work. This often means they can be arranged to run in parallel or to overlap, depending on the technical dependencies between products.

A. Technical stages can only occur sequential: This is incorrect. Technical stages can be sequential, parallel, or overlapping, depending on the nature of the specialist work.
B. Technical stages define where management decisions are appropriate: This describes management stages. The end of each management stage is a key decision point for the Project Board.
D. Technical stages define the commitment of resources and authority to spend: This is a function of management stages. The Project Board commits resources and authorizes expenditure for one management stage at a time.

Section 6.2.2

Technical stages

Page 60: "Technical stages may overlap

whereas management stages do not." This directly supports option C as the correct answer and refutes option A.

Section 6.2.1

Management stages

Page 60: "Management stages are partitions of the project with management decision points... At the end of each stage

the project board assesses the continuing viability of the project and authorizes the next stage." This confirms that options B and D are characteristics of management stages

not technical stages.
