Test Your Knowledge

Evaluate your understanding of technical documentation for ML projects by completing this knowledge check. This will help you identify areas where you may need to review the material.

You join a team working on an ML fraud detection system. The repository contains only code files with no README, data dictionary or notes. What's the biggest risk for the team?

A) Engineers will need extra time to tune hyperparameters.B) The model will fail to achieve acceptable accuracy.C) Team members won't be able to understand, reproduce or maintain the model effectively.D) Compliance officers won't be able to read the source code.

Which example best demonstrates documentation that supports the work of other team members?

A) Writing a README that includes installation commandsB) Adding code comments that restate what the code does line by lineC) Creating a data dictionary that defines features, types and meaningD) Keeping personal notes in a private folder for your own reference

Your head of product asks for documentation on a churn prediction model. What should you prioritise?

A) Detailed preprocessing code and GPU requirementsB) A model card summarising purpose, business impact, limitations and ethical considerationsC) A list of hyperparameters with their tuning rangesD) Dependency lists in requirements.txt

You present the same documentation to both your head of product and a junior data scientist. One feels overwhelmed by jargon; the other says the content is too vague. What principle did you fail to apply?

A) Using visuals such as diagrams to simplify contentB) Maintaining documentation in version controlC) Audience-specific language and a layered documentation approachD) Adding more code comments for clarity

Your team has built an ML model to predict equipment failures in a manufacturing plant. You need to document it for three groups — executives, compliance officers and engineers. Which approach best demonstrates tailoring documentation with a layered approach?

A) Create a two-page business report for executives and stop there, as they approve budgets.B) Deliver a single 50-page technical manual covering architecture, hyperparameters and system logs.C) Write a one-page summary explaining purpose, outcomes and business impact, then provide layered links to compliance details and full technical documentation.D) Build three separate documents for each group, tailored to their needs.

A team dropped a variable due to multicollinearity but never recorded the decision. Months later, new hires reintroduced it, causing errors. What maintenance practice would have prevented this?

A) Logging key design decisions and trade-offs in documentationB) Adding more visuals to the documentationC) Conducting a documentation review at project launchD) Using a model card for business leaders

Which of the following best reflects 'documentation as code'?

A) Storing meeting notes in a shared driveB) Generating documentation automatically from code comments or docstrings using tools such as Sphinx or DoxygenC) Using GitHub issues to track bugs in documentationD) Writing detailed release notes after every sprint

During a sprint review, you discover documentation describing an old model version that's no longer in production. What's the best corrective action?

A) Delete the outdated documentation immediately.B) Leave the documentation as-is, as older versions might be reused.C) Update the documentation to reflect the current model and archive prior versions clearly.D) Add a disclaimer that 'details may be out-of-date'.

You're asked why your team uses model cards instead of freeform reports. What's the best justification?

A) They reduce the time needed to write documentation.B) They provide a standardised, accessible format that balances technical and non-technical needs.C) They allow executives to skip reading technical details altogether.D) They are required by all ML frameworks.

During a sprint review, a teammate argues that writing documentation is unnecessary because 'the code already explains everything'. What's the strongest counterargument?

A) Well-written code eliminates the need for extra explanations.B) Documentation preserves critical decisions, builds trust with non-technical stakeholders and ensures the project remains maintainable over time.C) The only real reason to write documentation is for compliance reviews.D) Documentation takes less time to produce than code, so it won't slow the team down.
