Why It Matters

Outdated dependencies become a liability quietly

Security patches missed for months, compatibility breaks discovered only after something fails, and small fixes that never get scheduled all compound over time.

Security Without a Rebuild

Security patches applied on a defined cycle

Dependencies are audited on a schedule, and security patches are applied and tested before they reach production, rather than waiting for an incident to force the issue.

  • Regular audit of dependencies in use.
  • Security patches tested in staging first.
  • Out-of-cycle patches for urgent issues.

Compatibility Kept Current

Dependencies updated before they become a problem

Version updates and compatibility fixes are scheduled ahead of end-of-support dates, so a system stays supported and current without a disruptive rewrite.

  • Updates tracked against end-of-support dates.
  • Compatibility fixes scoped before they break something.
  • Every change logged with a before and after version.

What a Patch Log Looks Like

Every update tracked from scheduled to applied

Illustrative example. Your actual patch log depends on the dependencies present in your stack.

How It Works

From an audit to a logged, applied update

1
Audit dependencies
Current versions are checked against what is outdated or flagged for a known issue.
2
Flag what needs attention
Outdated or vulnerable packages are scheduled by urgency.
3
Patch and test
Updates are applied and tested in a staging environment first.
4
Apply in production
Changes go live during an agreed maintenance window.
5
Log and notify
The update is logged with before and after versions, and you are notified.

FAQ

Software Maintenance, answered

What does software maintenance cover?
Dependency updates, security patches, compatibility fixes and small improvements to an existing system, tracked in a patch log so you can see what changed and when.
How often are dependencies updated?
On a regular cycle agreed up front, plus out-of-cycle patches whenever a security issue is flagged as urgent.
How is a security patch tested before going live?
Every patch is applied and tested in a staging environment first, then moved to production during an agreed maintenance window.
What is the difference from a full rebuild?
Maintenance keeps the existing system current through updates, patches and small fixes. A full rebuild replaces the system itself, which is a separate, larger engagement.
Will maintenance include small feature improvements?
Yes, small improvements that do not require a rebuild are handled alongside patches and updates, inside the same maintenance cycle.
What if a client's stack has custom dependencies?
Custom or internal dependencies are audited alongside third-party ones, and each is logged with its own update and testing cycle.

Software Maintenance Features

How Software Maintenance Works

From a dependency audit to a logged, applied update. Here is how patches move through testing before they reach production.

Core Process

Audit, test and release, in that order

Dependency Audit

Every dependency checked against what is current

Third-party and internal packages are checked against their current versions and known vulnerabilities, so outdated or flagged dependencies are found before they cause a problem.

  • Full dependency list reviewed on a cycle.
  • Vulnerabilities flagged by severity.
  • End-of-support dates tracked ahead of time.

Patch Testing

Staging first, production second

Every update is applied in a staging environment and tested against the application before it is scheduled for a production maintenance window.

  • Applied and tested in staging first.
  • Compatibility checked against the live application.
  • Scheduled into an agreed maintenance window.

Release and Logging

A patch log you can check against every release

Each update is applied to production and logged with its before and after version, so there is a clear record of what changed and when.

  • Applied during the agreed window.
  • Logged with before and after versions.
  • Notification sent once the update is live.
