Data Gathering Techniques
Data gathering techniques are a family of tools used to collect information and data from various sources to support project planning, analysis, and decision-making.
Explanation
Data gathering techniques encompass a broad set of methods project managers use to collect relevant information from stakeholders, team members, and other sources. The PMBOK Guide identifies several specific data gathering techniques including brainstorming, interviews, focus groups, questionnaires and surveys, benchmarking, and checklists. The choice of technique depends on the type of information needed, the number of participants, time constraints, and the project context.
These techniques are used across multiple process groups, from collecting requirements during planning to gathering lessons learned during project closure. Effective data gathering provides the foundation for sound analysis and decision-making throughout the project lifecycle.
Project managers should consider combining multiple data gathering techniques to triangulate information and reduce the risk of incomplete or biased data. The selected techniques should be appropriate for the organizational culture and the stakeholders involved.
Key Points
- •Includes brainstorming, interviews, focus groups, surveys, benchmarking, and checklists
- •Applied across all process groups from initiation through closing
- •Technique selection depends on context, participants, and information needs
- •Combining multiple techniques improves data quality and reduces bias
Exam Tip
Know which specific data gathering technique is best for each situation. The exam often tests whether you can match a technique to a scenario.

Cost Performance Index (CPI) is an EVM efficiency metric that measures cost performance as the ratio of earned value to actual cost: CPI = EV / AC.
Schedule Performance Index (SPI)
Schedule Performance Index (SPI) is an EVM efficiency metric that measures schedule performance as the ratio of earned value to planned value: SPI = EV / PV.
