Clarify who defines non-functional requirements, frame boundaries with the client and analyst, and set realistic service level targets, API response times, and concurrent-user goals backed by real numbers.

Guide the client to define non-functional requirements such as performance, SLA, load, and users. Ensure the architecture rests on functional requirements to avoid production failures.

Determine the application type for a system by analyzing requirements and functional versus nonfunctional needs, then compare pros and cons of web app, web api, mobile, console, service, and desktop.

Explore web apps as the dominant application type, driven by a request-response model between a web server and browser, using HTML, CSS, and JavaScript to power user interfaces.

Explore web api concepts, including json data, rest api, and client–server interactions using url parameters and http verbs for data retrieval in a request–response model.

Explore how mobile apps run on smartphones, connect with web APIs, and leverage GPS to deliver interactive experiences for games, social apps, and news content.

Explore console applications that run in the command line, display only text, and require technical knowledge, triggered by typing commands with parameters for long-running or focused tasks.

Explain how services differ from console apps by lacking a user interface and being managed by a service manager that starts, stops, and monitors long running tasks using configuration files.

Understand desktop applications as self-contained software running on the local PC with offline capability and robust user interfaces. Distinguish them from web-based rich clients that use cloud APIs.

Explore how the cloud era offers application types, including function as a service with AWS Lambda or Azure Functions, enabling short code with no servers, while systems mix multiple types.

Explore how to select a technology stack for a system, weighing irreversible decisions, team skills, and schedule impact, while comparing front end, back end, and data store options.
