Triple Bottom Line (People, Planet, Profit)

The triple bottom line (TBL) is a framework that evaluates organizational performance across three dimensions: social impact (People), environmental impact (Planet), and financial performance (Profit).

Explanation

The triple bottom line challenges the traditional view that organizational success is measured solely by financial profit. Under TBL, a truly successful organization—and by extension, a truly successful project—creates positive outcomes across all three dimensions: social equity, environmental stewardship, and economic viability.

For project managers, TBL means considering the broader impact of project decisions. Does the project create fair employment? Does it minimize environmental harm? Does it generate sustainable financial returns? These questions move beyond traditional scope-schedule-cost metrics to encompass the project's full impact on society and the environment.

PMI has increasingly incorporated sustainability into its standards. PMBOK 7th Edition lists stewardship as a core principle, and the PMI Code of Ethics addresses social responsibility. On the exam, expect questions about how project managers should balance financial objectives with social and environmental considerations.

Key Points

  • Three dimensions: People (social), Planet (environmental), Profit (financial)
  • Challenges purely financial measures of success
  • Aligns with PMI's stewardship principle
  • Increasingly relevant to project selection and evaluation

Exam Tip

Remember the three Ps: People, Planet, Profit. PMI expects project managers to consider all three dimensions, not just financial returns.
