You've just fixed a usability problem and are about to release the updated app or website... but have you really got it right this time? Is there an unusual use case you haven't thought of? Can you ever be sure? Thankfully, applying formal methods to your design can help you.
Formal methods are usually employed in mathematical and scientific fields, as the preferred way of presenting information. Many mathematical and scientific theories we know today are in fact written in a formal manner. The scientific theory of gravity, for instance, is presented with all variables, parameters, and factors clearly named and defined, and all assumptions explicitly stated. The power of formalism is that it allows a concept, theory, or model to be completely and clearly defined, so anyone who reads it can easily spot any gaps in logic or exceptions to the rule.
When applied to design, formal methods allow designers to flesh out the entire product (e.g., all the states of an app) explicitly and completely. This allows designers to spot potential flaws in the design (e.g., incomplete user flows, links, or buttons that are not defined in the design, etc.) in less time.
In this course, you will learn how various forms of formal notation and methods can help you catch potentially disastrous problems early in a design process. Formal design methods will also give you confidence that the delivered systems are both what you intended and as free from major usability flaws as possible. You will also learn how to use formal methods to increase the probability that the developers will deliver precisely the design you intended.
What you will learn
- An introduction to formal methods, and examples of how formalism can help in design problems
- A brief history of the development of formalisms (in logic, mathematics, and science)
- How to use dialogue notation, such as state transition networks, to present the different states in your designs as well as annotate any danger states that might be present
- What states are, and what the various kinds of states that can exist in an interactive product are
- How to model and specify the states of a design in a detailed manner
Who should take this course
This is an advanced-level course on formal methods, and it is recommended for designers with some form of experience:
- UX designers keen on boosting their workflows by incorporating formal methods into their designs
- Project managers looking to improve the product development process with formalism
- Software engineers interested in creating a close integration of design and development, by using models and notations to specify designs
- Entrepreneurs keen on creating products that are free from major usability flaws
- Newcomers to design who are considering making a switch to UX design
