|Deploy/Maintenance||<Using Royce’s top 10 principles for modern software management, pick three that apply to this stage.>||Installation Guide
Note: An artifact is typically referred to as a by-product that is produced during the software development life cycle. Examples of architects are requirements, use cases, class diagrams, designs, project plans, test plans, etc.
Documentation in software development typically refers to user guide, training manuals, installation guide, online help, etc. Users need documentation to run the system successfully.
Artifacts can be considered as documentation that is an output from a phase in SDLC into another phase of the SDLC. For example, a requirements artifact is created by a Business Analysist during the requirements gathering phase and then passed to the Systems Analysts and the Architects to create the systems architecture and design. The same requirements artifact can also be passed to testers to create their test plans and test scenarios, as well as technical writers to create documentation outlines.
Documentation is always part of deliverables. However, artifacts may not be unless it is stated in the contract as part of custom solutions development.
