What are Agile Methodologies? What are the three key principles of the Agile Methodologies?

The Agile Methodologies are a response to the problems associated with the traditional SDLC methodology. The Agile Methodologies group argues that software development methodologies adapted from engineering generally do not fit with real-world software development. The three key principles are a focus on adaptive rather than predictive methodologies, a focus on people rather than roles, and a focus on a self-adaptive process.

Explain the importance of the maintenance phase in the SDLC process.

The fifth and final phase in the SDLC is maintenance. When a system (including its training, documentation, and support) is operating in an organization, users sometimes find problems with how it works and often think of better ways to perform its functions. Also, the organization's needs with respect to the system change over time. In maintenance, programmers make the changes that users ask for and modify the system to reflect evolving business conditions.

Training, Requirements, Design, Implementation, Verification, Release, and Response

false

An organizational approach to systems analysis and design is not driven by methodologies.

false

Maintenance is a separate phase and not the repetition of the other life cycle phases to study and implement the needed changes.

false

List the outputs delivered from each of the SDLC phases

planning: priorities for systems and projects. Analyzing: description of the current system, where problems and opportunities are and recommendation and how to fix it. Design: provides functional detailed specifications of all system elements and an acquisition plan for new technology. Implementation provides: code, documentation, training procedures, and support capabilities. Maintenance: include new versions or releases of software with associated updates.

Explain object-oriented analysis and design.

refers to systems development methodologies and techniques based on objects rather than data or processes. The goal of OOAD is to make systems elements reusable. OOAD is often called the third approach to systems development, after the process oriented and data-oriented approaches. The object-oriented approach combines data and processes (called methods) into single entities called objects.

According to Griss, finding and fixing a software problem after the delivery of the system is often far more expensive than finding and fixing it during analysis and design.

Describe the criticism of traditional waterfall SDLC process.

One relates to the way the life cycle is organized. Note how the flow of the project begins in the planning phase and from there runs "downhill" to each subsequent phase, just like a stream that runs off a cliff. It became too tempting to ignore the need for feedback and to treat each phase as complete unto itself, never to be revisited once finished.

The fourth phase in the SDLC is implementation. The physical system specifications, whether in the form of a detailed model or as detailed written specifications, are turned over to programmers as the first part of the implementation phase.
