A software development methodology is essentially a set of procedures utilized in the construction of computer software. They are like some kind of codified formal communication which enables you to lay down certain guidelines as to how the data will be passed among a team of individuals. It is also necessary to define what this means in terms of business development, business management and profitability. Basically, there are various phases involved in developing software according to this methodology.
The Software Development Life Cycle begins with the concept being conceptualized and then brought to reality through an alpha version. This version is known as an “Asch” or an “As Decay”. After the Asch phase, the beta or “itizer” stage is taken where the application or tool is tested and fixed. The goal is to identify any flaws and correct them before releasing the application.
There are different types of such software methodologies. Agile is one of them. This includes four different types of principles which are known as the Scrum methodologies. These are defined by Jean M. Auel, who is considered as one of the top experts on this subject. He has documented different types of Agile methods and their advantages. According to him, each principle of the Agile methodologies should be checked individually and collectively.
Another type of this methodology that has been used in this regard is the Rapid Application Development Methodology. It also belongs to the list of Agile software development methodologies. As the name suggests, this methodology adopts an interactive user interface design. The software developers create a model using the user guides and then customize it to fit the requirement of the client.
A variation of the Agile methodologies is the Extreme Programming. It is based on eight iterations, each of which is shorter than the previous one. Each iteration adds one more challenge to the developer. This type of methodology has been very successful in increasing the agility of the products developed.
An important aspect of the Scrum method is the testing process. Its acronym sdlc stands for short-cycle testing, which means that there are no cycles between the testing and the production of the product. Testing is done within the release process of the software development life cycle. Since the team members play a crucial role in the complete testing process, the term scrum master is often used to describe them.
A relatively newer methodology, known as Lean Manufacturing, has been widely adopted by manufacturing teams across the globe. In this system, the concept is to create a lean production model where every single process is designed around a specific goal, and this goal is achieved through quality improvements. The team members work to achieve the customer requirements by doing away with the waste. Lean manufacturing tries to remove all the factors that can degrade quality such as spending on unnecessary activities. The main advantage of this software development methodology, other than saving costs, is that it ensures that the product or the service delivered is of high quality.
Both the Agile and the waterfall processes can be modified depending on the requirements of the client. Their differences are mainly in their methods of delivery. Agile and waterfall methods have their own advantages and disadvantages and it is best to understand them and work accordingly. So, the next time you hear the terms Scrum, Six Sigma and Extreme Programming, know how they relate to your business needs and expectations.
Both waterfall and agile methods have various levels of development capability and each of these levels includes a testing procedure. During testing, the team works together to check the software application thoroughly and also works together to improve it. The testing procedure is a very important part of software development methodologies because the failure of the testing will lead to a lot of issues which may lead to cost over-runs and ultimately to a finished product that does not meet the clients’ requirements. Extreme programming, on the other hand, focuses more on the design aspect and less on testing and hence the developers are allowed to focus more on the conceptualization phase of the design. Team building is also done during extreme programming so that the developers learn to work together as a team and outsource functions to other developers who are experts in the respective field of the function being developed.
There are different software development methodologies available today and you should choose one that best suits your requirements. Before selecting a particular methodology though, you should first determine the aim and vision of your organization and the way in which the software should be designed, developed, deployed and maintained. Since different organizations have different requirements, the developers need to choose the appropriate software development methodologies that would best suit their needs. They should make use of all available resources and hire the services of the professionals who can give them good results.
All the three different software development methodologies include different phases which include the development stage, pre staging and testing stages. In the first stage, the developers work together to define the requirements of the clients and gather sufficient information about the same. Staging is a crucial stage as it enables the developers to ensure that the functionality of the application is correct and the features being provided are functional. In the second phase, the application is built according to the defined functionality and the modifications made are tested. In the last stage, the application is deployed and provides complete satisfaction to the clients.
