The PRISM methodology
Five lenses for examining a consequential platform decision.
PRISM helps organize evidence across platform architecture, reliability, infrastructure economics, scalability, and maturity inside a Platform Decision Review.
One platform diagnosis. Five connected dimensions.
PRISM connects architecture, reliability, economics, scalability, and maturity so leadership can see which bottlenecks reinforce each other.
P
Platform Architecture
Can the platform architecture support the company’s next growth stage?
Supporting lens
AWS Well-Architected concepts
Leadership implication
Weak boundaries and reactive architecture slow delivery and increase operational risk.
R
Reliability
Can customers depend on the platform as growth increases?
Supporting lens
SRE concepts
Leadership implication
Reliability gaps put customer trust, enterprise deals, and roadmap momentum at risk.
I
Infrastructure Economics
Is infrastructure spending creating business value or silently leaking margin?
Supporting lens
FinOps
Leadership implication
Weak cost visibility reduces margin and makes investment trade-offs harder to defend.
S
Scalability
Can the platform scale without breaking reliability, cost, or engineering execution?
Supporting lens
Architecture review
Leadership implication
Unknown capacity and reactive scaling threaten onboarding, cost, and commercial commitments.
M
Maturity
Can engineering sustain growth operationally?
Supporting lens
DORA / Accelerate metrics
Leadership implication
Low maturity slows delivery, concentrates knowledge, and reduces engineering leverage.
Grounded in recognized disciplines
PRISM borrows from the best operating thinking available.
PRISM is the internal diagnostic structure. The underlying concepts come from proven platform operating disciplines.
P — Platform Architecture
- AWS Well-Architected concepts
- Team Topologies
- Platform boundaries
- Architecture trade-off analysis
R — Reliability
- SRE concepts
- Incident management
- Observability
- SLO thinking
- Operational readiness
I — Infrastructure Economics
- FinOps
- Cost allocation
- Unit economics
- Cost ownership
- Cloud spend governance
S — Scalability
- Architecture review
- Capacity planning
- Data and platform scaling
- Performance bottleneck analysis
M — Maturity
- DORA / Accelerate metrics
- Platform engineering maturity
- Operating model
- Ownership
- Capability maturity models
PRISM uses recognized operating concepts as supporting context. It does not imply certification, endorsement, partnership, official affiliation, or a formal third-party audit.
Operating maturity · Levels 1–5
PRISM Maturity Index™
Where your platform operates today — and where it needs to be.
Reactive
Everything depends on heroes and manual recovery.
Managed
Basic processes exist, but growth creates friction.
Standardized
Teams have clearer ownership, standards, and repeatable operations.
Scalable
The platform enables growth with stronger reliability, cost visibility, and autonomy.
Strategic Platform
The platform becomes a competitive advantage.
Use the methodology on a real platform decision.
The Platform Decision Review applies these lenses to evidence, options, and trade-offs around one consequential decision.
