Ortem Technologies Framework
Ortem Software Delivery Performance Index (OSDPI)
A practical framework for assessing how prepared a software project is to move from planning to reliable delivery.
OSDPI v1.0 • September 2026
TL;DR
- OSDPI evaluates 10 weighted dimensions of software delivery readiness, each scored 0-5.
- The weighted result produces a single score from 0 to 100.
- A separate Critical Readiness Gate — plus a Security Readiness gate — flags major constraints that an overall average score can otherwise hide.
- The calculator returns your overall score, readiness classification, readiness gap, strongest and weakest dimensions, and recommended next actions.
Calculate your OSDPI score
Rate each dimension 0-5. Nothing you enter leaves your browser — the score is calculated locally and there is no sign-up, no email gate and no server round-trip.
0 of 11 dimensions rated
Product Clarity
Requirements, priorities, business rules and decision readiness
Not yet rated
›Why this matters
Unclear product decisions do not disappear during development — they resurface as rework, scope disputes and late-stage redesign once they can no longer be absorbed cheaply.
Architecture Readiness
Architecture, technical decisions and system boundaries
Not yet rated
›Why this matters
Architecture decisions made too late, or never made explicitly, tend to constrain cost, scale, security and delivery sequencing in ways that are expensive to reverse.
Team Capability
Required skills, seniority and role coverage
Not yet rated
›Why this matters
A team can be fully staffed by headcount and still be missing the specific capability the project actually needs — role coverage matters more than team size.
Execution Flow
Work breakdown, dependencies between tasks and delivery coordination
Not yet rated
›Why this matters
Without a working process for sequencing and coordinating tasks, individual skill and effort do not reliably convert into shipped, validated progress.
Quality & Testing
Test coverage, QA capability and defect prevention
Not yet rated
›Why this matters
Defects found late cost more to fix and erode confidence in the release — testing that is added at the end rather than built in tends to arrive too late to change that.
Deployment Readiness
Environments, CI/CD, release process and rollback capability
Not yet rated
›Why this matters
A working application is not the same as a releasable one — without a repeatable deployment process, every release carries avoidable risk.
Feedback Speed
Speed of discovering and resolving incorrect assumptions or defects
Not yet rated
›Why this matters
Slow feedback does not just delay individual tasks — it lets incorrect assumptions travel further into the build before anyone notices them.
Dependency Readiness
APIs, credentials, data, infrastructure and third-party dependencies
Not yet rated
›Why this matters
A team can execute perfectly and still be blocked by a dependency it does not control — an average score elsewhere will not remove that constraint.
Operational Readiness
Monitoring, security, backups and production support
Not yet rated
›Why this matters
A system that was never designed to be operated tends to fail quietly in production — readiness here determines how fast a real incident gets caught and fixed.
Ownership & Continuity
Documentation, knowledge distribution and ability to transfer responsibility
Not yet rated
›Why this matters
Software that only one person understands is a single point of failure — continuity risk stays invisible right up until that person is unavailable.
Security Readiness
Authentication, access control, encryption and vulnerability handling — a separate gate, not one of the 10 weighted OSDPI dimensions.
Not yet rated
›Why this matters
Security gaps are gated separately because they can be catastrophic even when every other readiness dimension looks strong — a good average should never mask a critical security failure.
Rate every dimension above to calculate your OSDPI score.
What OSDPI measures
Product Clarity
15%Measures whether the business problem, target users, workflows, requirements and success criteria are sufficiently understood to support delivery decisions.
Unclear product decisions do not disappear during development — they resurface as rework, scope disputes and late-stage redesign once they can no longer be absorbed cheaply.
Architecture Readiness
10%Measures whether the major system boundaries, technical decisions, integrations, data flows and non-functional requirements are sufficiently defined.
Architecture decisions made too late, or never made explicitly, tend to constrain cost, scale, security and delivery sequencing in ways that are expensive to reverse.
Team Capability
15%Measures whether the people responsible for delivery have the necessary technical, product, design, QA, DevOps and domain capabilities.
A team can be fully staffed by headcount and still be missing the specific capability the project actually needs — role coverage matters more than team size.
Execution Flow
10%Measures whether the project has a practical delivery process for turning requirements into validated increments.
Without a working process for sequencing and coordinating tasks, individual skill and effort do not reliably convert into shipped, validated progress.
Quality & Testing
10%Measures whether quality engineering, testing strategy, acceptance criteria and defect management are built into delivery.
Defects found late cost more to fix and erode confidence in the release — testing that is added at the end rather than built in tends to arrive too late to change that.
Deployment Readiness
10%Measures whether environments, release processes, CI/CD, configuration and deployment responsibilities are prepared.
A working application is not the same as a releasable one — without a repeatable deployment process, every release carries avoidable risk.
Feedback Speed
10%Measures how quickly the team can obtain decisions, reviews, user feedback and clarification.
Slow feedback does not just delay individual tasks — it lets incorrect assumptions travel further into the build before anyone notices them.
Dependency Readiness
5%Measures whether external systems, vendors, APIs, data, approvals and other dependencies are sufficiently available and understood.
A team can execute perfectly and still be blocked by a dependency it does not control — an average score elsewhere will not remove that constraint.
Operational Readiness
10%Measures whether monitoring, logging, backups, incident handling, support and production operations are prepared.
A system that was never designed to be operated tends to fail quietly in production — readiness here determines how fast a real incident gets caught and fixed.
Ownership & Continuity
5%Measures whether code, infrastructure, documentation, credentials, domains, accounts and operational ownership are clearly controlled and transferable.
Software that only one person understands is a single point of failure — continuity risk stays invisible right up until that person is unavailable.
Security Readiness
Gate, not weightedMeasures whether the security controls, access management and vulnerability-handling process appropriate to this system are in place.
Security gaps are gated separately because they can be catastrophic even when every other readiness dimension looks strong — a good average should never mask a critical security failure.
Why the score needs context
A high OSDPI score does not guarantee project success. A low score does not automatically mean a project should be cancelled. The score is intended to expose readiness conditions that influence delivery risk — the purpose is to improve decisions before problems become expensive.
"OSDPI is a decision-support framework, not a promise of project outcome."
How to interpret the score
The critical-gate concept
Five dimensions — Product Clarity, Architecture Readiness, Team Capability, Dependency Readiness and Operational Readiness — are checked individually. If any of them scores below 2/5, the assessment flags a critical readiness constraint regardless of the overall score, because a foundational weakness there is not something other strengths can offset. Security Readiness is checked the same way as its own separate gate.
Sample assessment
A B2B workflow SaaS application with a web application, role-based access, third-party payment integration, document uploads, email notifications, reporting and cloud deployment.
| Dimension | Score | Weight | Contribution |
|---|---|---|---|
| Product Clarity | 4/5 | 15% | 12.0 |
| Architecture Readiness | 3/5 | 10% | 6.0 |
| Team Capability | 4/5 | 15% | 12.0 |
| Execution Flow | 3/5 | 10% | 6.0 |
| Quality & Testing | 4/5 | 10% | 8.0 |
| Deployment Readiness | 3/5 | 10% | 6.0 |
| Feedback Speed | 4/5 | 10% | 8.0 |
| Dependency Readiness | 2/5 | 5% | 2.0 |
| Operational Readiness | 3/5 | 10% | 6.0 |
| Ownership & Continuity | 4/5 | 5% | 4.0 |
| OSDPI Score | 70 / 100 — Strong | ||
Security Readiness scored 4/5, so the security gate passed. Dependency Readiness (2/5) is the lowest weighted score here — but since it sits at the critical-gate threshold rather than below it, the critical gate still passes.
The lowest-scoring dimensions — Dependency Readiness, Architecture Readiness, Execution Flow — drive the recommended next actions the calculator would show for this project: Resolve access or availability gaps on dependencies that block core workflows. Review architectural assumptions against expected usage and integrations. Tighten the handoff between requirements, development and review so work moves predictably through the pipeline.

OSDPI for different decisions
Methodology
OSDPI uses ten weighted dimensions, each scored 0-5. The weights total exactly 100%. Each dimension's score is normalized (divided by 5) and multiplied by its weight; the ten contributions sum to a final score between 0 and 100.
A separate critical-gate layer exists because some risks should not be hidden by an average score. Five of the ten dimensions are checked individually against a threshold; Security Readiness is treated as its own separate critical gate outside the 100-point formula entirely.
OSDPI is an Ortem Technologies analytical framework. It is not currently presented as an industry-wide statistical benchmark. OSDPI is designed to surface delivery-readiness conditions that can inform software project planning and decision-making — it does not predict project success.
Future research / evidence base
OSDPI is currently a methodology rather than a published empirical benchmark. As Ortem Technologies accumulates appropriately anonymized project data, the framework can be evaluated against real delivery outcomes such as schedule variance, budget variance, scope change, defects, production incidents, rework and operational performance.
