Development Principles

CFTS software and automation are developed primarily to solve operational problems.

The same principles used when designing networks, power systems, storage, hosting, or recovery environments also apply to software: understand the requirement, reduce unnecessary complexity, define responsibilities, document the result, and make sure it can be supported over time.

Use the Simplest Suitable Approach

A solution should be no more complicated than the problem requires.

This may mean using:

an established commercial or open-source platform
integration between existing systems
a small script or service
a purpose-built application

The preferred option is the one that meets the requirement while remaining understandable and supportable.

Build Around the Requirement

Technology should follow the operational need rather than determine it.

Before developing a tool, CFTS considers:

what problem is being solved
who needs to use it
what systems it depends on
what happens when it fails
what access it requires
what information it stores or exposes
how it will be maintained
whether an existing product already solves the requirement adequately

Keep Control Boundaries Clear

Applications should only receive the access they need.

Where possible, CFTS prefers narrowly defined interfaces and APIs over giving applications broad administrative access to infrastructure.

This is particularly important for automation, client portals, diagnostic systems, and AI-assisted tooling.

Design for Failure and Recovery

Software is part of the infrastructure and can fail like any other component.

Where appropriate, CFTS considers:

configuration backup
data backup
rollback
dependency failure
logging
service restart
rebuild procedures
documented recovery steps

A tool that cannot be recovered or understood may eventually become a liability even if it initially solves the problem well.

Keep Humans in the Operating Model

Automation should remove repetitive work and make information easier to use, but it should not obscure what the infrastructure is doing.

CFTS therefore aims to keep systems observable and understandable to the engineers responsible for them.

For higher-risk actions, human approval or intervention may remain part of the process even where much of the surrounding work is automated.

Documentation Is Part of the Build

Documentation is not treated as an optional final step.

Where practical, developed systems should have enough information to explain:

their purpose
major dependencies
access requirements
operating boundaries
backup or recovery considerations
normal maintenance
known limitations

The level of detail depends on the system, but the objective is consistent: reduce dependency on undocumented individual knowledge.

Avoid Unnecessary Lock-In

CFTS generally prefers designs that preserve operational choice.

This does not mean avoiding proprietary products. It means understanding the dependency created by a product, platform, API, or service before making it critical to an operating environment.

Where practical, data should remain exportable, configurations should be documented, and replacement or recovery paths should be understood.

Review Rather Than Preserve for Its Own Sake

An internally developed tool should not continue indefinitely simply because CFTS built it.

If a mature product later provides a better, safer, or easier-to-support solution, replacing an internal tool may be the correct engineering decision.

The objective is the service outcome, not ownership of the software.
