6 Basic SDLC Methodologies:which one is Best

Development of the Life Cycle Software (SDLC) is a software development world for an auditor: errors can be made in order to create software before receiving (precious). But more than that: Of course: SDLC can also develop a plan that will make it all the better for the first time.

The SDLC system includes several different stages, including planning, analysis, design, construction, testing, implementation and maintenance. Here are six SDLC models, or models, a group of development groups use these efforts.

Here are methods for software development.

• Agile

• Lean

• Waterfall

• Iterative

• spiral

• DevOps

Each of these phases have slightly different conditions than others, but everyone has a common goal to make teams quick and profitable to deliver high quality software as possible.

If you look at a summary of six SDLC methods, you can find out what's best for your group:

1. Agile

The Agile system has been in existence for a decade. But recently, they have become an important force for software development for many organizations. Some companies evaluate the two methods currently used for other types of projects, including non-technical efforts.

In the Agile process, "sudden error" is a good thing. This method creates frequent cycles, each one of the small changes that arise from premature release. Every equipment, products are tested. A reliable way to help groups identify and solve short-term problems before projects become more tangible and engage in the involvement of stakeholders and fully respond to the development process.

In the context of the adoption of this approach, many groups also implement a workable approach to help develop complex structures. Combined groups operate in sprints, which generally take two to four weeks to complete assigned tasks. Daily roundtables help the whole team to monitor the progress of the project. In ScrumMaster, the task of team supervision is focused on his mission. (For more information on Scrum, visit the Scrum Alliance website).

2. Lean

the software development model is based on the principles and practices of light products. Seven non-fat principles (ie.) Are: eliminating trash, strengthening education, late determination, giving as soon as possible, combining, building loyalty and watching.

Lean Policy works only when it works at that time, so there is not much room for many things. Project teams also focus on waste reduction opportunities in SDLC, eliminating unnecessary paper cuts.

The agile system is actually compromised for SDLC, but some differences can be detected. One is how everyone focuses on customer satisfaction: creating a first priority from the beginning, creating a flexible process by which project teams can respond quickly to respond to all stakeholders of the SDLC. On the other hand, fats emphasize that garbage can generate greater value for the general customer, which helps to improve satisfaction.

3. Waterfall

Some experts argue that the model model is never intended to model the process of real projects (see the discussion on this topic in StackExchange) a. However, the cascading model is the oldest of SDLC formats. It's also a very simple way: finish once and then proceed. No return. Each phase is based on information from the previous stage and has a specific project plan.

The problem with water is difficult. It's definitely easy to understand and facilitate. However, older delays can be transferred from the entire schedule. In a small recovery room at the end of the process, you can not solve the problem until you reach the repair phase. This method can not work well, if necessary or if the project is lengthy.

An even stricter model of V-shaped identification and validation This approach has developed the direct development of the cascade process. It is recognized by the development phase of the development phase. As a ranking waterfall, each stage begins as soon as it is completed. In this case, the SDLC can be useful until your project meets uncertain requirements.

4. iterative

The unique system is a continuation of the structure. Instead of being fully familiar with the terms, project groups implement software requirements, then test, evaluate and refer to other terms. A new kind of software is being developed at each level or level. Squeeze and repeat until the entire system is ready.

The benefits of an iterative model for other forms of public SDLC must prepare a working version of the project at the beginning of the process, making it cheaper to implement the changes. One of the disadvantages: a repetitive process can quickly use resources.

An example of a strategic approach is the Integrated Integrated System (RUP) issued by IBM Software. As explained, this IBM behind is a "production system", it is designed to increase productivity as the team "captured a lot of the best ways to develop software, a modern design suitable for a wide range of projects and organizations."

RUP is divided into four development processes: initially, when the concept of the project was established; for further details when this project has been identified and evaluated; construction, when the project is completed and completed; and transit when products are produced. Each phase of the project includes planning, business analysis and design, implementation, testing and referral.

5. Spiral

One of the simplest SDLC methods, the spiral model is based on repetition and re-process; project through four phases (planning, risk analysis, engineering and evaluation) and re-"withdrawal" until it ends, which allows a lot of circles.

The spiral system is usually used for large projects. It enables research teams to create a highly customized product that includes user comments at the start of the project. Another advantage of SDLC is risk management. Iskudhufin every start according to the risk and get the best way to prevent or reduce the looge.

6. DevOps

The Devops method is the latest in SDLC. As explained in this article came from two trends: effective and fat free use of traditional work tasks, and general business trends see the value of collaboration and the development of human resources activities at all levels of the SDLC process.

In the DevOps model, the development and operation of the team work closely together, and sometimes as a group, to promote innovation and deployment of software, and has a high quality and reliability. The updating of the goods is small, but often. Discipline, continuous feedback on processes and automation of the development of the book are all DevOps model models.

Amazon Web Services defines DevOps as follows: "DevOps is a combination of philosophy and culture, culture, and tools to increase the organization's ability to deliver high-speed applications and services: develop and improve things as quickly as possible organizations using the software development process and managing traditional infrastructure. "But, like many SDLCs, DevOps is not just about planning and performing work, but also Philosophy requires a major change in the mind and body of the organization.

The correct SDLC option for software development software requires a careful review. But do not forget that the way you plan and improve your project is part of the performance. More importantly, we bring together a team of strong and competent and dedicated teams to develop the project through any obstacle or unexpected.
