In this section, we will focus on the concepts of software development life cycle called “agile”. The Agile software development methodology helps in building a software through addition sessions in short iterations of 1 week to about a month so the development is lined up with changing business prerequisites.
There are 12 principles that describe the Agile methodology in detail −
The highest priority is given to clients concentrating on the prerequisites through early and continuous delivery of valuable software.
Changes are acceptable during software development. Agile processes is designed to work in order to match the client’s competitive advantage.
Delivery of a working software is given to customers within a span of one week to about a month.
Business analysts, quality experts and developers must cooperate during the whole life cycle of project.
Projects should be structured with a clan of motivated individuals. It gives an environment to help individual colleagues.
Face-to-face conversation is the most productive and effective method of sending information to and inside a development team.
Measuring progress is the key that helps in characterizing the progress of project and software development.
Agile process focusses on sustainable development. The business, the engineers and the users should be able to maintain a constant pace with the project.
It is required to maintain regular attention to technical excellence and good design to improve the agile functionality.
Agile process keeps everything simple and uses simple terms to measure the work that isn't finished.
An agile team should be self-organized and should be independent with the best architecture; prerequisites and designs emerge from self-composed teams.
It is important to review the work at regular intervals so that the team can reflect on how the work is advancing. Reviewing the module on a timely basis will improve execution.
Daily stand-up refers to the daily status meeting among the colleagues. It gives updates related to the software development. It additionally refers to addressing obstacles of project development.
Daily stand-up is a required practice, no matter how an agile team is established regardless of its office location.
The list of features of a daily stand-up are as per the following −
The duration of daily stand-up meet should be roughly 15 minutes. It should not extend for a longer duration.
Stand-up should include discussions on status update.
Participants of this meeting normally stand with the intention to end up meeting quickly.
A story is usually a requirement, which is formulated in few sentences in simple language and it should be finished within an iteration. A user story should incorporate the following characteristics −
All the related code should have related check-ins.
The unit test cases for the specified iteration.
All the acceptance test cases should be defined.
Acceptance from product owner while characterizing the story.
Scrum can be considered as a subset of agile methodology. It is a lightweight procedure and incorporates the following features −
It is a process framework, which incorporates a set of practices that need to be followed in predictable order. The best representation of Scrum is following iterations or sprints.
It is a “lightweight” process meaning that the process is kept as small as possible, to augment the productive output in given duration specified.
Scrum process is known for its distinguishing procedure in comparison with different methodologies of traditional agile approach. It is divided into the following three categories −
Roles characterize the colleagues and their roles included throughout the process. The Scrum Team consists of the following three roles −
The Scrum artifacts provide key information that each member should be aware of. The information includes details of product, activities planned, and activities finished. The artefacts defined in Scrum framework are as per the following −

Time boxes are the user stories which are planned for each iteration. These user stories help in depicting the product features which form part of the Scrum artefacts. The product backlog is a list of user stories. These user stories are prioritized and forwarded to the user meetings to decide which one ought to be taken up.
Scrum Master collaborates with every member of the team. Let us now see the interaction of the Scrum Master with other teams and assets.
The Scrum Master interacts the product owner in following manners −
Discovering techniques to achieve effective product backlog of user stories and managing them.
Helping team to understand the necessities of clear and concise product backlog items.
Product planning with specific environment.
Ensuring that product owner knows how to increase the value of product.
Facilitating Scrum events as and when required.
The Scrum Master associates with the team in several ways −
Coaching the organization in its Scrum adoption.
Planning Scrum implementations to the particular organization.
Helping employees and stakeholders to understand the requirement and phases of product development.
Working with Scrum Masters of different teams to increase effectiveness of the application of Scrum of the specified team.
The Scrum Master communicates with organization in several ways. A few are mentioned below −
Coaching and scrum team associates with self-organization and includes a feature of cross functionality.
Coaching the organization and teams in such areas where Scrum is not fully adopted yet or not acknowledged.
Scrum helps clients, colleagues and stakeholders work together. It incorporates timeboxed approach and continuous feedback from the product owner ensuring that the product is in working condition. Scrum provides advantages to different roles of the project.
The sprints or iterations are considered for shorter duration and user stories are designed according to need and are taken up at sprint planning. It ensures that every sprint delivery, client requirements are fulfilled. If not, the requirements are noted and are planned and taken for sprint.
Organization with the help of Scrum and Scrum masters can focus on the efforts required for development of user stories thus reducing work overload and avoiding rework if any. This also helps in maintaining increased efficiency of development team and client satisfaction. This methodology also helps in increasing the capability of the market.
The fundamental responsibility of the product managers is to ensure that the quality of product is maintained. With the help of Scrum Masters, it becomes easy to facilitate work, gather quick responses and absorb changes if any. Product managers also confirm that the designed product is aligned as per the client requirements in every sprint.
With time-boxed nature and keeping sprints for a smaller duration of time, development team becomes enthusiastic to see that the work is reflected and delivered appropriately. The working product increments each level after every iteration or rather we can call them as “sprint”. The user stories which are designed for every sprint become client need adding up more value to the iteration.
Scrum is a productive framework within which you can develop software in teamwork. It is completely structured on agile principles. ScrumMaster is there to help and co-operate the team of Scrum in every possible way. He acts like a personal trainer who helps you stick with designed plan and perform all the activities as per the plan. The authority of ScrumMaster should never extend beyond the process. He/she should be potentially capable to manage every situation.
