Designing a new product is a messy process. It involves initial brainstorming, rough concepts, false starts, and extensive refinement. Good designs begin with an identified need or opportunity, and they’re based on a solid understanding of the product’s requirements. No matter how skilled the requirements analyst is or how informed and cooperative the customer participants are, the first set of requirements they develop will be only approximately correct. It takes a process of iterative refinement and validation to accurately understand the requirements for any nontrivial product.

Studying for your IIBA certification (CBAP, CCBA, or ECBA) can be a rigorous but ultimately fulfilling experience. But there is nothing worse than putting in all that time, work, and commitment and then FAILING the actual exam. Several disappointed candidates have sought guidance from me, unfortunately, after failing their first attempt at the exam. Before moving forward with these candidates, the first thing I do is get an understanding of the steps they previously took to study for the exam. This not only helps me get a baseline of how I can help them, but it also serves as inputs for how I can build courses and study tools that address these issues. So, to help you increase your chances of passing your IIBA exam on your first attempt, here are some of the top reasons people fail their IIBA exam.

With the massive shift to working from home we now see a plethora of tech companies flogging new employee surveillance tools. You can readily see their appeal to command-and-control thinkers. If you think, as they do, that managing employee activity is crucial, then to know who’s doing things and who’s taking the mickey is grist to their mill. But these tools will undermine performance and morale.

Think about it from the employee’s point of view. Your boss can see your emails, any documents you read or create, your appointments, who you talk to, and when; can listen to or read transcriptions of your calls. Your boss can see your computer screen, can monitor your internet use, the sites you visit and for how long. Your boss can even turn on your camera and watch you at work.

Product configuration requirements are a specialized type of requirement when an information system supports product-related needs through data values. Where there are specific changes to business processes needed to sell and/or operate a new product, the requirements for the information system to support activities within those processes involve standard functional requirements.

Whether an information system can support a product though configuration or requires custom development, when an information system is involved there are standard pre-go-live activities that need to be performed (e.g. testing). Requirements support those activities.

A diagram is a 2-dimensional representation of a story, which shows elements and their relationships on a single canvas. An element is shown on a single diagram. (To show the same element information on a 2 diagrams, the element is duplicated.) When the properties of a diagram element are changed, the change is reflected only on that diagram.

A model is a 3-dimensional representation of a collection of related stories, which captures diagram elements as model components. A component includes all element properties and relationships between different elements on all diagrams. A single model component can be shown as elements on several diagrams. A change to the properties of a diagram element or model component is reflected on every diagram where that component is displayed.

A model does not necessarily need to include any diagrams. Diagramming is the most common method for creating and maintaining model components, but the diagrams can be deleted without changing the model.

If a picture is worth a thousand words, then a diagram converts those words into a story. A model organizes those stories into a book.
