SDLC - April 2017

SDLC stands for Software Development Life Cycle. It is a systematic approach to develop software by following a set of processes, methodologies, and guidelines. It encompasses all the phases involved in software development, such as requirement gathering, system design, coding, testing, deployment, and maintenance. The SDLC ensures that the software is developed efficiently, meets the client's requirements, and is of high quality.

Project managers are responsible for overseeing and managing the entire system development process. They assign tasks to staff members, manage the budget and reporting, and ensure that all deadlines are met. They play a crucial role in coordinating and facilitating the various aspects of a project, ensuring that it is completed successfully and within the allocated resources.

Debugging is the process of finding and correcting errors in the program code. This involves identifying and fixing any mistakes or bugs that may be causing the program to not function as intended. It is an essential step in the software development process to ensure that the program runs smoothly and produces the desired results. Debugging involves analyzing the code, identifying the cause of the error, and making the necessary corrections to resolve the issue.

During the Maintenance and Evaluation step in the SDLC, enhancements, upgrades, and bug fixes are carried out. This step involves monitoring and maintaining the software system to ensure its smooth functioning and to address any issues that may arise. It also includes evaluating the system's performance and making necessary improvements to enhance its efficiency and effectiveness.

The Capability Maturity Model (CMM) is not a software life cycle model. It is a framework used to assess and improve an organization's software development processes. The CMM focuses on process improvement and maturity levels, rather than providing a specific model for software development. In contrast, the Spiral Model, Waterfall Model, and Prototyping Model are all examples of software life cycle models that provide structured approaches for developing software.

During the development and documentation step in the SDLC, the actual programming of software code takes place. This is the phase where the software is built based on the design and analysis done in the previous steps. The development process involves writing and testing the code to ensure it functions correctly. Documentation is also created during this step to provide information about the software, such as user manuals and technical specifications.

The first step in the software development life cycle (SDLC) is problem/opportunity identification. This step involves identifying and understanding the problem or opportunity that the software is intended to address. It involves gathering requirements, conducting research, and analyzing the current situation to determine the need for the software. This step is crucial as it sets the foundation for the rest of the SDLC phases, such as analysis, design, development, and documentation, which come after problem/opportunity identification.

The software development life cycle (SDLC) is a process that outlines the various stages involved in developing software. It typically includes requirements gathering, design, coding, testing, deployment, and maintenance. These six stages are essential in ensuring the successful development and implementation of software. Therefore, the correct answer is 6.
