Scrum software development process

Team is responsible for designing, development, testing and other processes. Scrum master is a leader and responsible for team management and proper management and techniques results in a form of effective solution. There are number of software development process are available for software development phase.

Scrum is declared best among all other software development processes because of its effectiveness, time saving skills and proper monitoring at every phase of project development. It reduces chances of failure and provides transparent monitoring to all team workers. Usually, waterfall method and spiral methodology are compared with scrum. Waterfall method works on set of rules which requires complete data instruction before improving on next step. Waterfall method works on well defined process, coding, testing, implementation and all other related steps needs to be finished before moving to next step.

Requirement and planning phase plans completion dates, final product and project cost during this phase. In this process any unpredictable or unexpected change can reduces probability of success up to high extent.

Spiral model and waterfall model both works efficiently but there is a lack of proper management and monitoring in this process which reduces their success rate. Spiral model always requires well defined process which includes several steps are required to be completed before moving on next step.

Spiral method is an iterative method but it is more iterative than other processes. In this process, assumption is always made that requirements once taken will remain same through out the cycle. Iterative process and completion dates can partially vary. Scrum method requires periodic sprint meetings during which any changes to the project are planned.

At the end of each sprint cycle or iteration a releasable feature is implemented. Due to these periodic meetings any sudden changes or unanticipated risk is better managed by using the scrum development process Rogers, Every process has some limitations and some requirements and some set of rules to follow, same in case of Scrum.

Usually, scrum is successful in number of cases, but in some conditions it also gets fail, there are number of preventive measures which should be done in order to prevent scrum failure. The first topic which needs to be cover in this domain is Scrum and CMM. Scrum improves quality of software development and management skills; it provides ease and support of monitoring project.

CMM Capability maturity model can be compared with Scrum in order to find out the best points among both. Post motern analysis is done at the end of each sprit cycle; at this stage all mistakes and problem are noted in order to prevent them in next cycle.

These are used to minimize such mistakes from occurring during later sprint cycles. So scrum improves the process step by step and it requires rules and techniques that need to be followed.

Scrum does continuous process refinement during the post analysis at the end of sprint phase. Scrum is powerful in number of situations, scrum has enough capability of dealing with changing requirements efficiently through out the development process. Scrum promotes the need of effective communication in order to produce effective solutions. It provides high transparency, better risk management and proper project monitoring at every phase Beck, With the aid of Scrum every team worker can be able to view the status and details of every phase during development cycle.

Thus scrum handles requirement changes, unpredictable events or any other personal changes better than other traditional processes. Scrum is suitable for small as well as it is also suitable for large projects. Scrum can also work with large projects and it has ability to deal with large amount of data with proper monitoring. Large projects usually involve complex customers and number of development and testing teams working across geographies.

It would be difficult for each of them to attend the scrum meeting. It is also difficult for the management to trust the whole team and make the project transparent to everyone. In most of the cases, customer does not like to participate in development of project, customer usually like to just sketch their requirements and want complete solution on deadline.

Customer do not like to attend meetings and check development phases, scrum solves this problem up to high extent as it follows incremental steps approach during development phase.

Usually dealing with large projects is not easy and number of software development processes fails at this stage. According to Ken scrubber, during software development process, 15 minutes meeting daily should be held in order to produce effective solution which must meet user requirements. Each software development process has some limitations, they work well up to high extent but after reaching some level they fail.

Scrum requires involvement of every team member in an effective way. Scrum follows some set of rules which require all members to follow and no one should skip scrum rules. If any team member denies attending meeting and reporting his task. Then the transparency and effectiveness of scrum meetings are compromised.

These meetings add live to the function of scrum, it helps in solving conflicts and dependencies occur during development process. In some cases, multiple product owners communicate about conflicting requirements during the meeting. Mostly, management does not understand the need and importance of scrum and do not believe in scrum terminologies and scrum techniques.

Scrum usually fails when there are less number of communications and improper handling of scrum. It also fails due to lack of training of both master and trainer. Lack of communication and training are two main reasons of scrum failure. There is a strong need of understanding scrum roles by Scrum Master and clear communication the backlogs and progress of the backlogs to both the product owner and the team members.

However, such failures can be controlled by hiring a certified Scrum master. Certified scrum master deals efficiently with scrum terminologies and techniques. Efficient and effective handling of scrum can prevent scrum failure in large organizations. Like a rugby team, Scrum instigates the team to learn through experiences and become self-organized when dealing with problems and improvement through reflecting on wins and losses. Generally, it is a framework for handling a project which focuses on teamwork, accountability, iterative progress toward achieving a well-defined goal.

Scrum is often assumed to be part of the agile software development process because the Scrum concept revolves around continuous improvement, which is a primary principle of agile. The framework begins with the simple acknowledgment that the team does not know about the details of every nook and corner of the project at the outset; rather, it is experienced by adapting to changing conditions and user requirements.

It plays the role of liaison between customers and the development team. He or she is the champion for their product. The product owner ensures that the expectation for the completed product has been communicated and agreed upon accordingly. As a facilitator who is the champion of scrum within the team, it is the primary responsibility of the scrum master to assure for carrying out scrum best practices in the project.

He or she schedules the needed resources for sprint planning, stand-up, sprint review, and the sprint retrospective. Works together for developing and testing incremental releases of the final product. The team members are the champions for sustainable development practices.

The usual scrum teams are five or seven members, tight-knit and co-located. The scrum method consists of certain processes or the set of sequential events that the scrum team performs regularly. These are some crucial events where the teams play a part. The product owner takes part in product backlog creation. It is the primary responsibility of the product owner to take a constant view of market and customer needs, and that is why he or she has to drive the product by the product vision.

This is an ongoing process, and the changes or new emergence accept as new opportunities rather than obstacles. Sprint planning meetings happen at the beginning of a project, and all the development team members have to participate in this meeting.

This meeting is led by a scrum master , where the team members and the product owner decide the goal of the sprint. Scrum is a software product development strategy that organizes software developers as a team to reach a common goal — creating a ready-for-market product.

It is a widely used subset of agile software development. The word scrum also is used in rugby to define a play where players struggle against each to gain possession of the ball.

The goal of a scrum in software development is to perform at a high-performing level like a rugby team does in a scrum. In a rugby scrum, all the players literally put their heads together. When it comes to software development, a scrum can be characterized by developers putting their heads together to address complex problems.

Rugby players try to gain control of the ball in the scrum and move it downfield. Software developers use scrum to move their projects quickly. And the benefits trickle down to software developers:.
