How do you check if your software documentation is accurate and usable?

Defining goals and audience is an imperative first step in assessing the quality of your software documentation. This preliminary assessment aligns closely with the concept of 'Documentation Driven Development,' where documentation isn't an afterthought but a phase integral to the development cycle itself. It's useful to employ metrics that can quantify the success of your documentation. These could include tracking user engagement, conducting A/B tests on different styles or formats, and using analytics to see which sections are most frequently visited or appear confusing to users. These data-driven approaches can offer valuable insights into whether your documentation is achieving its intended purpose and resonating with its audience.

It is great to be clear on what is the purpose of your documentation. For example, sometimes simple, straightforward documentation is preferable in developer community. Meanwhile for business would require more context. It is easy to fall into trap of overwriting irrelevant information and get lost in documentation when we are not clear about the goals and audience.

Imagine explaining a complex video game strategy to a friend who's never played before – you might unintentionally skip important steps, assuming they're obvious. This "Curse of Knowledge" sneaks into software documentation too. When we're sorting out who our documentation is for and why we're creating it, we're battling this issue. By stopping to think about our audience and their familiarity, we're sidestepping the trap of assuming everyone's on the same page. It's like making sure our video game guide isn't just for pros but also caters to beginners. Defining goals and the audience for our documentation serves as a shield against the Curse of Knowledge, ensuring our instructions are crystal clear for all levels of expertise.

I disagree with Eleni, if the goal is accurate documentation, then the concepts need to be reviewed and the tasks needs to be tested. Analytics don’t provide information on accuracy, but defects (internal and from customers) do. A goal should be less calls to customer support. Eleni used a bunch of fancy phrases that are nice, but in the end don’t provide the data. If you want great documentation, you need to hire great content developers. And if you are looking for a great content developer, hire me.

To ensure accurate and usable software docs: Expert Validation: Have experts review for accuracy. User Testing: Test with real users for clarity. Clear Language: Avoid jargon, be concise. Visuals Help: Use images for complex steps. Easy Navigation: Enable search, logical layout. Version Info: Specify software version for relevance. Feedback Loop: Gather user input, update accordingly. Accessibility: Ensure compliance with standards. Follow these steps for effective documentation.

Adhering to documentation standards and best practices is pivotal for producing high-quality, usable content. While tools like spelling and grammar checkers are valuable, they're just the tip of the iceberg. One often overlooked best practice is the peer review of documentation, akin to code reviews in software development. Peer reviews provide a fresh set of eyes that can catch ambiguities, errors, or omissions that automated tools may miss. Also, as your product evolves, your documentation should be tested just like any other component of your software. Automated tests that check if code snippets in your documentation actually run can save immense time and frustration for your end users.

You may also provide a list of abbreviations you have used throughout the document. You may also add a glossary to give any background information on some frequently used technical terms to give a suitable context to the reader or users of the document.

Make sure to have a style guide as part of your standards. For example, when referring to buttons in the application, the label of the button is always in bold font in the text. Having a key with the conventions for the user can also be helpful, but even just having consistency without a key makes a big difference. Using the same style guide for all software documentation, internal and external, would be the gold standard.

Testing documentation with actual users closes the feedback loop and validates your assumptions about its clarity and utility. Methods like usability testing can be as simple as a 'walkthrough,' where you observe a user navigating through the documentation to accomplish a specific task. Likewise, advanced analytics can reveal 'hotspots' where users frequently drop off or seem to struggle, suggesting areas for improvement. Also, while surveys and interviews can provide subjective feedback, coupling this with objective data like time-on-page or search query logs can give you a better view of your documentation's effectiveness.

The best documentation tester I ever had was someone who wasn't tech savvy, knew they weren't tech savvy and would always ask questions rather than guess. For that particular software system, they were always the second person to go through the annual process using the updated instructions. I made sure to let them know how valuable they were because they were pure gold for validating documentation usability.

Think of documentation reviews as akin to code reviews—they're not just about finding errors but also about improving readability, structure, and even performance, in the sense of how efficiently the documentation helps users achieve their goals. The peers you choose for reviews should not just be those who are intimately familiar with the project. Including team members who have a fresh perspective or different levels of expertise can uncover issues that might be invisible to those too close to the project. Additionally, using checklists during reviews can provide a structured approach to ensure that all critical aspects, such as clarity, completeness, and accuracy, are evaluated.

This is one of the best ways to make sure your documentation is up to date. Whenever possible, if you include code examples in your documentation, you should have tests that execute that code! One great example is the doctest module for Python that will execute code in embedded documentation and test that the correct output is produced. This makes sure that the examples you write don't become out of date.

Automated tools are helpful, but it's crucial to balance automation with human oversight. Tools can catch syntax errors and style inconsistencies, but they may not catch more subtle issues like ambiguities or outdated conceptual explanations.

Few example documentation structure, screenshots, snippets will be beneficial. This article currently looks wordy, maybe rethink on adding bullets, summary, conclusion, images to make it more interesting for the readers.

You can leverage AI ChatGPT or Grammarly to check your spelling and grammar. Make sure the words you choose communicate your intent clearly

Different stakeholders have different documentation needs and many documents serve as agreements between various points of view. Requirements capture user expectations. They then get translated into specifications which in turn get mapped into code. As code evolves, the documentation should explain what changes are being made and why.
