Decision Tools | Engineering Decision Support
Explore transparent calculators and detailed decision reviews. Work through your assumptions, identify missing evidence and take a practical action plan back to your team. PDF reports are available without an email.
Start with the question you face.
Cloud, incident and AI workflow cost tools calculate scenarios from numbers you provide. The others help you work through trade-offs and the evidence behind them. Every result explains its limits.
A starting point, not a verdict.
Use the output to make the next conversation specific. A calculator cannot inspect your architecture, contracts, customers, or actual billing data. We show the assumptions, avoid invented percentages, and leave the final decision with your team.
Economics & reliability
AWS migration business-case calculator
Compare staying with moving to AWS, including migration costs, overlapping bills, confirmed credits and the operating cost after credits expire.
The decision: Does the migration still make financial sense without temporary incentives?
Open toolEconomics & reliability
Project cash schedule and funding headroom
Compare entered cash, delayed support and no additional support against a calendar-month delivery schedule. Credits are not cash, and headroom is not profit.
The decision: Can entered capital cover the month-end cash gap?
Open toolAI & operations
AI cost per accepted result calculator
Compare two evaluated AI workflows using model usage, retrieval, human review and operating costs. Check acceptance and safety before comparing cost per useful result.
The decision: Which evaluated workflow meets your quality requirements at a sustainable cost?
Open toolEconomics & reliability
Cloud cost drift
See how an assumed monthly change compounds across 12 months, then compare the scenario with your billing data.
The decision: Which cost change deserves investigation before it becomes the new baseline?
Open toolEconomics & reliability
Incident cost and reliability
Estimate directly observed incident-response labor and, only if you supply it, hourly revenue exposure.
The decision: What is the known annual response burden, and what remains unmeasured?
Open toolArchitecture & technology
Refactor vs rebuild
Identify whether change can be isolated, or whether a replacement path needs to be tested.
The decision: Can you deliver the next outcome without replacing the whole system?
Open toolArchitecture & technology
Vendor dependency review
Decide where a managed service is worth its switching cost and where an exit path matters.
The decision: Which dependency would be expensive to reverse?
Open toolArchitecture & technology
Build vs buy
Separate strategic differentiation from commodity capability and integration burden.
The decision: Where does owning the implementation create lasting value?
Open toolArchitecture & technology
Architecture complexity
Ask whether distributed components solve an observed constraint or add coordination cost.
The decision: Which architectural boundary has earned its complexity?
Open toolArchitecture & technology
Platform or product boundary
Clarify when a shared internal capability needs product ownership rather than a one-off service.
The decision: Who is the customer of this shared capability?
Open toolAI & operations
Production AI readiness
Review production AI controls across purpose, data, evaluation, authority, deployment and operations. Build an evidence-based action plan, not a readiness score.
The decision: Can this AI workflow be operated safely when it is wrong?
Open toolAI & operations
Enterprise readiness
Surface operational requirements that feature-complete products often miss.
The decision: Could a demanding customer trust this service in production?
Open toolDelivery & teams
Technical debt timing
Choose whether to repair a constraint now, contain it, or defer with an explicit trigger.
The decision: What will this debt block before the next planned change?
Open toolDelivery & teams
Execution drag review
Locate handoffs and decision delays using observed delivery flow rather than a synthetic velocity score.
The decision: Where does work wait after engineering begins?
Open toolDelivery & teams
Delivery pod vs staff augmentation
Compare ownership and integration needs before comparing vendor rates.
The decision: Do you need capacity within your team, or ownership of an outcome?
