CMMI Measurement & Performance Metrics 1 — Questions and Answers
Question 1: What is the primary purpose of the Measurement and Analysis (MA) process area in CMMI?
- To develop measurement capabilities that address organizational information needs and objectives (Correct answer)
- To document all project activities and outcomes for auditing purposes
- To establish risk mitigation strategies based on data collection
- To define quality attributes for software products
Correct answer: To develop measurement capabilities that address organizational information needs and objectives
The MA process area develops and sustains a measurement capability aligned with information needs so that meaningful data drives decision-making.
Question 2: At which CMMI maturity level are quantitative management techniques first formally required?
- Maturity Level 2
- Maturity Level 3
- Maturity Level 4 (Correct answer)
- Maturity Level 5
Correct answer: Maturity Level 4
Maturity Level 4, 'Quantitatively Managed,' is the first level that formally requires statistical and quantitative process management techniques.
Question 3: What is a Process Performance Baseline (PPB) in CMMI?
- A documented characterization of the expected range of process performance based on historical data (Correct answer)
- A minimum performance threshold that all projects must exceed
- A baseline configuration of process documents stored in a repository
- A set of industry benchmarks used to compare organizational performance
Correct answer: A documented characterization of the expected range of process performance based on historical data
A PPB characterizes the expected range of process performance using selected measures derived from historical data, enabling future performance predictions.
Question 4: In CMMI, what is a 'base measure'?
- A measure defined in terms of two or more other measures
- A measure defined by a measurement method applied directly to a specific attribute (Correct answer)
- The minimum acceptable value for a quality metric
- A foundational process area required at all maturity levels
Correct answer: A measure defined by a measurement method applied directly to a specific attribute
A base measure captures data directly — it is defined by a measurement method applied to an attribute without derivation from other measures.
Question 5: Which paradigm is most commonly used in CMMI to systematically derive measures from information needs?
- SMART objectives framework
- Goal-Question-Metric (GQM) paradigm (Correct answer)
- Balanced Scorecard methodology
- Six Sigma DMAIC process
Correct answer: Goal-Question-Metric (GQM) paradigm
The Goal-Question-Metric (GQM) paradigm links organizational goals to questions that characterize achievement, then to specific metrics that answer those questions.
Question 6: What distinguishes a leading indicator from a lagging indicator in CMMI process measurement?
- Leading indicators measure past performance; lagging indicators predict future outcomes
- Leading indicators predict future performance; lagging indicators reflect past outcomes (Correct answer)
- Leading indicators are quantitative; lagging indicators are qualitative
- Leading indicators apply to suppliers; lagging indicators apply to internal teams
Correct answer: Leading indicators predict future performance; lagging indicators reflect past outcomes
Leading indicators provide early signals that allow prediction of future outcomes, while lagging indicators reflect results that have already occurred.
Question 7: What is a 'derived measure' in the context of CMMI measurement?
- A measure obtained directly by counting or observing an attribute
- A measure computed from two or more base measures using a defined formula (Correct answer)
- A measure derived from industry standards rather than internal project data
- A qualitative assessment converted to a numerical rating scale
Correct answer: A measure computed from two or more base measures using a defined formula
A derived measure is calculated from base measures using a defined formula (e.g., defect density = defects / size), providing additional analytical insight.
