User Requirements - Correct Answer-* Describes what activities that users must be able to perform * Also called "user needs" System Requirements - Correct Answer-Technical specifications used to develop the system and meet the user requirements. User Stories - Correct Answer-Plain-language description of a user's need for the software under development, usually phrased as "(who) wants to (do what) so that they can (do what)". Agile Development - Correct Answer-A software development methodology that delivers functionality in rapid iterations, measured in weeks, requiring frequent communication, development, testing, and delivery. Usually carried out by small teams. Highly responsive to changing requirements. Best used for small to medium-sized projects. Plan-driven development - Correct Answer-A method of software development where all activities are planned in advance. Progress is measured against the plan. Waterfall Model - Correct Answer-The most popular model. In this cycle, each phase must be completely finished before the next begins Eight codes of ethics. (Not sure how important this one will be to know so don't stress over it. ¯_(ツ)_/¯) - Correct Answer-1. PUBLIC - Software engineers shall act consistently with the public interest. 2. CLIENT AND EMPLOYER - Software engineers shall act in a manner that is in the best interests of their client and employer consistent with the public interest. 3. PRODUCT - Software engineers shall ensure that their products and related modifications meet the highest professional standards possible. 4. JUDGMENT - Software engineers shall maintain integrity and independence in their professional judgment. 5. MANAGEMENT - Software engineering managers and leaders shall subscribe to and promote an ethical approach to the management of software development and maintenance. 6. PROFESSION - Software engineers shall advance the integrity and reputation of the profession consistent with the public interest. 7. COLLEAGUES - Software engineers shall be fair to and supportive of their colleagues. 8. SELF - Software engineers shall participate in lifelong learning regarding the practice of their profession and shall promote an ethical approach to the practice of the profession. Sections of a plan to support a dependable process. - Correct Answer-* Introduction * Roles and responsibility * Requirements, process, and review. * Verification activities * Audit plan (See study guide for more detail) Fields of a test case table - Correct Answer-* ID for indexing * Input * Steps involved in carrying out the test * Expected result of the test Software process activities - Correct Answer-* Specification * Design and implementation * Validation * Software Evolution Why use Agile ? - Correct Answer-* Reduced risk * "People not processes" * Better quality product * Flexibility to make changes and at a reduced cost. * Less overhead * Focused on end-user * Emphasis on feedback from customer. This saves time by allowing things to get fixed sooner rather than later. * Documentation isn't required * Product can be delivered in increments which allows for a quick release and capture of feedback Fields of a hazard analysis - Correct Answer-* Hazard description * Causal factor (What caused it) * Consequence (Result of factor) * Severity (Low - High) * Probability * Risk (Low - High) * Control / Mitigation (How to prevent) SCRUM - Correct Answer-The most common framework for Agile Development. Uses small teams to produce small pieces of deliverable software using sprints, or 30-day intervals, to achieve an appointed goal. Scrum master is appointed to manage this. Pipe and filter architecture - Correct Answer-Modularity, reuse, anticipation of change Monolythic architcture - Correct Answer-"Single-tiered software application in which different components combined into a single program from a single platform." Event Driven Architecture - Correct Answer-A style in which system components react to externally-generated events and communicate with other components through events N-version programming - Correct Answer-A form of redundancy that involves multiple functionally equivalent programs that are independently generated from the same initial specifications.
