View Original View Raw

Summary

This article covers the definition, history, phases, benefits, and disadvantages of the System Development Life Cycle (SDLC) methodologies, tools, and applications. It explains the different types of SDLC, the history of SDLC, the phases, the benefits and drawbacks, and the software solutions that support SDLC. It also covers project management, software development life cycles, and how to choose the right SDLC methodology. Finally, it provides a template for managing SDLC with Smartsheet.

Q&As

What is a System Development Life Cycle?
A System Development Life Cycle is a phased project model that defines the organizational, personnel, policy, and budgeting constraints of a large scale systems project.

What are the benefits of a well-defined System Development Life Cycle?
Benefits of a well-defined System Development Life Cycle include the ability to pre-plan and analyze structured phases and goals, basing costs and staffing decisions on concrete information and need, providing verification, goals, and deliverables that meet design and development standards for each step of the project, developing extensive documentation throughout, improving the quality of the final system with verification at each phase, and having a clear view of the entire project, the personnel involved, staffing requirements, a defined timeline, and precise objectives to close each phase.

What are the disadvantages of a Structured System Development Life Cycle?
Disadvantages of a Structured System Development Life Cycle include that many of the methods are considered inflexible, difficulty in responding to changing circumstances in the life cycle, considering the structured nature of SDLC to be time and cost prohibitive, testing at the end of the life cycle, and the documentation involved in a structured SDLC approach can be overwhelming.

What is another form of SDLC?
Another form of SDLC is the Software Development Life Cycle, which follows an international standard known as ISO 12207 2008.

What software solutions support the System Development Life Cycle?
Software solutions that support the System Development Life Cycle include Oracle, Airbrake, Veracode, and Smartsheet.

AI Discussion

Me: It's about System Development Life Cycle (SDLC). It covers the history, definition, phases, benefits, and disadvantages, along with solutions that support the system development life cycle. It also talks about the Software Development Life Cycle and different models and methods for implementing the SDLC.

Friend: Interesting. What are the implications of this article?

Me: Well, the article highlights a number of important points. Firstly, it shows that SDLC is a complex process that involves numerous steps and components. It also emphasizes the importance of having clear objectives for each phase of the process, as well as the necessity to have a project manager to oversee the entire process. Furthermore, it also discusses the various software solutions and frameworks that can be used to support the SDLC. Finally, it underlines the importance of data and information security, as well as compliance with relevant regulations.

Action items

Research and compare different SDLC methodologies to determine which one is best suited for your organization.
Create a timeline with milestones and dependencies to track progress of the SDLC.
Utilize a software solution to help manage the SDLC process, such as Smartsheet, to provide visibility to key stakeholders and create a central repository for documentation.

Technical terms

System Development Life Cycle (SDLC): A process used to develop information systems through a series of steps, including analysis, design, implementation, testing, and maintenance.
Waterfall Method: A traditional engineering process that closes each phase upon completion.
Agile Method: A software-based system that provides feedback through an iterative process.
Prototype Method: A plan to build numerous software methods that allow different elements to be “tried-out” before fully developing them.
Rapid Application Development (RAD): A hybrid of the prototype method, but works to de-emphasize initial planning to rapidly prototype and test potential solutions.
Spiral Method: Provides more process steps, which are graphically viewed in a spiral formation and is generally credited to provide greater flexibility and process adaptation.
Baseline: A measure of performance that includes start date, end date, phase/stage duration, and budget data.
SAMM: The Software Assurance Maturity Model is a framework that aids organizations in evaluating their software security practices, building security programs, demonstrating security improvements, and measuring security-related activities.
Sarbanes-Oxley: A regulation that impacts organizations differently, but is most commonly used for data integrity.
COBIT: A regulation that impacts organizations differently, but is most commonly used for data integrity.
HIPAA: A regulation that impacts organizations differently, but is most commonly used for data integrity.
