A practical way into the library

Start with the decision — not a technology shortlist

Most software projects go wrong before development begins. The guide helps you define the operating problem, identify the evidence you need and move to the right specialist material.

Decision guides

Compare options by evidence, not sales claims

Use clear criteria: process fit, implementation effort, control, ongoing cost, risk and the ability to exit.

Costs and ownership

Budget beyond the build

Discovery, licences, integrations, hosting, monitoring, support, change and exit all affect total cost.

One-offDiscovery · build · migration · acceptance
RecurringCloud · licences · support · monitoring
Often missedChange · documentation · supplier exit
Understand web-application cost
Control the assets

Ownership is more than source code

  • Business accounts Domain, cloud, repositories and billing access
  • Operational evidence Backups, monitoring, runbooks and deployment process
  • Exit readiness Data export, licences, documentation and transition support
Review source-code ownership
Risk and assurance

Questions that protect day-to-day operations

Security is only one part of assurance. Permissions, recovery and evidence must also work in the real operating model.

Security

Threats, authentication, dependencies, data and specialist review.

Permissions

Roles, approvals, least privilege and access reviews.

Backups and recovery

Recovery objectives, restore testing and operational ownership.

Audit logs

Record material actions without collecting everything indefinitely.
