consistency in software design

Example 1: iPhone The Apple iPhone follows all four forms of design consistency in from both a hardware and software perspective. As with any software development endeavour, an MVP offers a timely release of a lighter preliminary version. Once you know Photoshop it is much easier to reuse the same knowledge to start using Illustrator and so on. Try Documentalist, my app that offers fast, offline access to 190+ programmer API docs. For example: code samples, usable code generation, support for testing are all good things to have that reduce the cost of using these entities over their alternatives. The code is smaller and therefore less prone to errors. Following is how it works: 1. While designing it is essential that the overall system should look unified, right from the fonts of the heading and body text to the colors used on the interface. It started great, the intern is super motivated. You can probably see now how well defined design entities lead to the various levels of consistency. In short, usability and learnability improve when similar elements have consistent look and function in similar way. Even if you have an official design standard in place and a mandate to follow it, people will forget about rarely applied elements of the standard and they will interpret more ambiguous parts of the standard in different ways. We don’t want our dear user to feel that, do we? Simple: methods (or functions), classes and modules. A usable and user-friendly design always provides a consistent experience. Thanks for your time! Be capable of looking through their eyes and feel through their hearts. Imagine that your controller doesn’t let you save to the database; this means you know to not search for the save code in the controller. Consistency in UI design is concerned with making sure elements in a user interface are uniform. Here are two nice sources to look into patterns out of many: You might argue that consistency could bore the heck out of the user. What artifacts can we use to design software? Utilising design consistency effectively allows the iPhone to quickly become simple and intuitive to use regardless of hardware model or software version. We want to constrain classes. And so on. Immutability seems to catch on, while Design by Contract is rarely used. Consistency Makes Sense. I try to define as much as possible our design entities and make it very clear how to use them: how to name them, when to throw exceptions, what they can and cannot do, what are the collaboration patterns that apply to them etc. The framework focuses on the higher levels of abstraction in a design, we refer to design at those levels of abstraction as architectural design. Having inconsistent interface is like trying to communicate with the user in several languages. The design consistency in Adobe software is apparent all-round, in the two examples below you will notice both software may have differences in applications, but the overall design of each node, the placement of each setting is contrast to each other, and toward the other software made by Adobe. It’s not because we weren’t trying. We need them to evolve to a better version. Good example of external consistency is the user interface of Adobe products.

Making these small changes will evolve the product into a better version and will keep the consistency. If you found this article useful tap the so others can enjoy it, too. Padding and margins need to be consistent in all similar elements (buttons, cards and etc.). Architecture Consistency (AC) aims to align implemented systems with their intended architectures. These are based on Jakob Nielsen’s 10 Usability Heuristics for UI Design , Ben Shneiderman’s The Eight Golden Rules of Interface Design , and Bruce Tognazzini’s Principles of Interaction Design .
