Use cases are written descriptions of how users use something, and in the case of web developments, they have been applied to software use. They include descriptions of the nature of software reactions and potentials, including features and processes, that are potentially relevant to a user’s needs or interests. They are generally developed as steps to follow to achieve objectives. In web development, they have been increasingly complex and in-demand.

Use cases can be advantageous to software developers and business owners in optimizing user-friendliness and experiences. This can result in improved perspectives of an organization or product, and therefore its net reputation. Businesses may therefore commonly regard them as strategic, capable of achieving sufficient ROI for the product and subsequent developments. Optimizing use cases may require research in addition to expertise. They can be of further value in explaining expected program responses and potential troubleshooting-related issues. Use cases typically do not address user interface details or implementation aspects.

Complete use cases include a range of elements that are strategically addressed in content detail. This ensures that the user is aware of potentially related and relevant elements. These elements include actors, stakeholders, events, triggers, conditions, primary success scenarios, and alternative outcomes. Writing use cases involve identifying the actors, defining actor interests, detailing processes and outcomes, and detailing alternatives (including errors and troubleshooting-related aspects).

Use cases have been increasingly helpful in increasingly complex IoT and software developments. These have included complex aspects such as evolving machine technology and AI integrations, programming developments, improving global connectivity capacities, and expanding social media mediums. Continuing to strategically development them for optimal user guidance remains strategic in terms of the same range of business concepts.
