Category Archives: Requirements Models

Different models, or documentation techniques for capturing requirements. Requirements models are the tools in a business analysts toolkit. Product and program managers also rely on requirements models as methods of documenting requirements.

Attainable Requirements

Unless you live in a world filled with unicorns and rainbows, writing realistic requirements is critical.  When you set unattainable goals, the best result you can hope for is a frustrated engineering team.  Write requirements that are attainable, and your team will surprise you with what they can achieve.

Design-Free Requirements

Design-Free requirements are important for two reasons, and hard for two other reasons.

Design-free requirements are hard because you “know what you want” when you should be documenting “why you want it.”  Writing design-free requirements can be hard when you don’t trust your development team to “do the right thing” even though it is not your job to design the solution.

Concise Requirements

Jump forward in time to the day of your next big product launch (first release, new features, new market segment, etc).  And your site/application crashes due to the “unexpected” demand.  All you can do now is look for a bucket of water to put out the fire.  What could you have done to prevent this disaster?  Jump back to today and start doing it!

Agile Non-Functional Requirements

Just because your requirement is not a user story does not mean you have to throw it out when planning your next sprint.  See one way (that is working) for managing non-functional requirements with an agile team.

User Stories and Use Cases

User Stories are one of the key agile artifacts for helping implementation teams deliver the most important capabilities first.  They differ from use cases in some important ways, but share more commonalities than you might think.

Agile Product Management: Providing Context

Agile development methodologies succeed because they help development teams be as effective as possible.  Development teams do not, however, work in complete isolation.  The company they work for has a strategy.  The company manages a portfolio of products, and targets a particular product at specific market problems.  Within that context, an agile team can thrive.  What’s the best way to provide that context?
