Use case writing is key to effective requirements management. Each use case represents a single idea or logically grouped behaviors. When you define a use case, there are several mistakes you can make. Preventing those mistakes is the first order of business. The second order of business is making sure that the use cases in the system work together. This requires an understanding of the context in which the use case happens. To fully understand a use case you have to know what is promised to be true before the use case happens, as well as what causes the use case to happen. These are subtly different.
Ten Ways To Be A Better Product Manager
In product management training, we spend a lot of time focusing on what we do. Adrienne reminds us that this isn’t enough, we also have to focus on how we do it, with her tips on how to be a better product manager.
Product Management and User Experience
There’s a buzz going around about the conflict and collaboration between product managers and user experience professionals. It started with a pair of articles co-written by Jeff Lash and Chris Baum. In short, with a user-centric view of products, both roles are responsible for the success of the user-interactions. Who makes the decisions?
Scheduling Product Releases
When you define a product roadmap, you also define the release dates for your product. Change happens. Your market changes, your customers change, your requirements change. Unpredictable events happen. Your competitors release a new killer feature, your developers have an epiphany (or run into a roadblock). Should you change your release schedule?
Agile Development and Software Maintenance Costs
Over 90% of the cost of software development is software maintenance (cite). This alarming trend was predicted as early as 1972. McKinsey suggests that CIOs should spend no more than 40-60% on maintenance. Gartner’s IT Spending and Demand Survey (2002) reports that CIOs are spending 80% of their budgets on maintenance (p12 of presentation). Agile development can help reverse this trend.
Product Life Cycle and the ROI of Agile Development
The product life cycle is a description of the presence or behavior of a product in the marketplace over time. The framework for description is a function of the sales volume of the product versus time. Over time, products are created and introduced, and sales grow, peak and decline. The product life cycle uses phases to describe these different periods in the life of a product. Understanding the product life cycle is also key to calculating the ROI of agile development.
User Centered Design and Bridging The Canyon of Pain
There is such a thing as too much choice. For new users, too much choice (or control) is too much. For experienced users, too little choice is a problem. Ease of use usually comes from reduced control – but users don’t stay “new” for long. There’s a “canyon of pain” to quote Kathy Sierra in that transition from “new” to “experienced.” We call them “competent” users and we have to help them cross the canyon of pain.
Business Requirements, Project Scope, and Coupling
Robin Goldsmith wrote an interesting article for RQNG about business requirements – what he calls “REAL” requirements. Gathering the right requirements demands more than just effective listening skills, you have to focus on the right problem. Robin brings up a theme we’ve discussed here in the past, and again in today’s article.
