WELL Details
What It Is
WELL Building Standard v2 is a performance-based certification framework administered by the International WELL Building Institute (IWBI). It focuses on designing, operating, and verifying buildings to advance human health and well-being through evidence-based strategies. Its people-first approach emphasizes measurable occupant outcomes via 10 core concepts like Air, Water, and Mind, using mandatory Preconditions and optional Optimizations.
Key Components
- **10 conceptsAir, Water, Nourishment, Light, Movement, Thermal Comfort, Sound, Materials, Mind, Community (+ Innovation).
- 24 Preconditions (pass/fail) and 102 Optimizations (points-based).
- Built on public health and building science research.
- Certification model: Bronze (40 points), Silver (50), Gold (60), Platinum (80), with concept minimums at higher tiers.
Why Organizations Use It
Drives productivity, tenant retention, ESG reporting, and higher rents. Mitigates health risks, complements LEED for holistic sustainability. Builds stakeholder trust via verified performance.
Implementation Overview
Multi-phase: gap analysis, scorecard development, documentation, on-site verification, recertification every 3 years. Applies to new/existing buildings, all sizes/industries; requires third-party testing.
CMMI Details
What It Is
Capability Maturity Model Integration (CMMI) is a globally recognized process improvement framework developed by Carnegie Mellon University's Software Engineering Institute and now governed by ISACA. It provides a structured approach to enhance organizational processes across development, services, and acquisition domains using maturity and capability levels.
Key Components
- 4 Category Areas (Doing, Managing, Enabling, Improving) with 12 Capability Areas and 25 Practice Areas in v2.0.

- Generic and specific practices for institutionalization.
- SCAMPI appraisals (Class A/B/C) for certification.
Why Organizations Use It
- Improves predictability, reduces rework, boosts quality (e.g., 34% cost reduction).
- Meets contractual requirements in defense, regulated sectors.
- Enhances risk management, stakeholder trust, competitive bidding.
Implementation Overview
- Phased approach: assessment, piloting, rollout, appraisal.
- Applies to mid-to-large organizations in IT, software, services.
- Involves training, tooling, change management; SCAMPI A for official ratings. (178 words)
