Documentation is the written record of all the important information about a product or process. It's like a user manual or guidebook that provides instructions, explanations, and details about how something works or should be done.

Think of it as the recipe book for your product, where you can find all the ingredients, measurements, and steps to follow. Documentation is crucial in product management because it helps everyone involved understand how the product works, troubleshoot issues, and make improvements.

Without clear and comprehensive documentation, it's like trying to bake a cake without a recipe - you'll end up with a mess! Good documentation saves time, reduces confusion, and empowers teams to work efficiently.
