The Twelve-Factor App methodology is a methodology for building software-as-a-service applications. These best practices are designed to enable applications to be built with portability and resilience when deployed to the web .
ALM is a broader perspective than the Software Development Life Cycle (SDLC), which is limited to the phases of software development such as requirements, design, coding, testing, configuration, project management, and change management. ALM continues after development until the application is no longer used, and may span many SDLCs.
The development team works closely with the client to analyze existing systems and workflows, determine technical feasibility, and define project milestones. Planning and design: Once the requirements are understood, the custom software development team proceeds to create a comprehensive project plan. This plan outlines the development roadmap ...
The project execution is the process of completing the tasks defined in the project plan. The purpose of project monitoring and control is to keep the team and management up to date on the project's progress. If the project deviates from the plan, then the project manager can take action to correct the problem.

This means a development environment, project management tools, etc. Factor 4: Finally, DSDM also states that a supportive relationship between customer and vendor is required.
A systems development life cycle is composed of distinct work phases that are used by systems engineers and systems developers to deliver information systems.Like anything that is manufactured on an assembly line, an SDLC aims to produce high-quality systems that meet or exceed expectations, based on requirements, by delivering systems within scheduled time frames and cost estimates.
