The quality dilemma is basically two fold: The issue is how to find a proper middle ground where your first users don’t feel like beta testers, but can still afford the software and have it come out in time to beat your competitors. Therefore you must be able to build something that is “good enough”…
If you were to ask someone on the street, what is quality – do you think they could answer? What do you think they would answer? Would it be the same are yours? Quality is a fairly complex topic, that means different things to different people. It is something that can be recognized, even if…
A design pattern can be characterized as “a three-part rule which expresses a relation between a certain context, a problem, and a solution” [Ale79] For software design, context allows the reader to understand the environment in which the problem resides and what solution might be appropriate within that environment. A set of requirements, including limitations and constraints, acts as…
An application should be designed so that it anticipates the user’s next move. Especially on a mobile device so the user doesn’t have to do as much on a small screen. The interface should communicate the status of any activity initiated by the user. This is especially important since you may have some time between…
Component-level design occurs after the first iteration of architectural design has been completed. At this stage, the overall data and program structure of the software has been established. A component is defined in UML as: “a modular, deployable, and replaceable part of a system that encapsulates implementation and exposes a set of interfaces.” However, different…
In building, there are styles known to architects. If you speak of a style, they know what you mean. An architectural pattern, like an architectural style, imposes a transformation on the design of an architecture. However, a pattern differs from a style in a number of fundamental ways: (1) the scope of a pattern is…
Software Architecture is the structure, or structures, of the system that comprise of software components, the externally visible properties of the components, and the relationships among them. Architecture is not operational software, rather it is representative to allow you to see how effective your design is and consider alternatives. It focuses on components. It may…
An MVP, or Minimally Viable Product, is a common process in the modern software world. It got famous as part of the Lean Startup model, and has grown in popularity. Let’s look at some reasons why. When looking at the design and model of your project, you may think you have a winner. But do…
