There are three roles in it, and their responsibilities are: Scrum Master: The scrum can set up the master team, arrange the meeting and remove obstacles for the process Product owner: The product owner makes the product backlog, prioritizes the delay and is responsible for the distribution of functionality on each repetition.

Scrum Team: The team manages its work and organizes the work to complete the sprint or cycle. Crystal: There are three concepts of this method- Chartering: Multi activities are involved in this phase such as making a development team, performing feasibility analysis, developing plans, etc.

Cyclic delivery: under this, two more cycles consist, these are: Team updates the release plan. Integrated product delivers to the users. Wrap up: According to the user environment, this phase performs deployment, post-deployment. Lean Software Development: Lean software development methodology follows the principle "just in time production. When frequent changes are required. When a highly qualified and experienced team is available. When a customer is ready to have a meeting with a software team all the time.

When project size is small. Efficient design and fulfils the business requirement. Anytime changes are acceptable. It reduces total development time. Disadvantages Cons of Agile Model: Due to the shortage of formal documents, it creates confusion and crucial decisions taken throughout various phases can be misinterpreted at any time by different team members.

Each build is incremental in terms of features; the final build holds all the features required by the customer. The Agile thought process had started early in the software development and started becoming popular with time due to its flexibility and adaptability.

These are now collectively referred to as Agile Methodologies , after the Agile Manifesto was published in Agile is based on the adaptive software development methods , whereas the traditional SDLC models like the waterfall model is based on a predictive approach. Predictive teams in the traditional SDLC models usually work with detailed planning and have a complete forecast of the exact tasks and features to be delivered in the next few months or during the product life cycle.

Predictive methods entirely depend on the requirement analysis and planning done in the beginning of cycle. Any changes to be incorporated go through a strict change control management and prioritization. Agile uses an adaptive approach where there is no detailed planning and there is clarity on future tasks only in respect of what features need to be developed. There is feature driven development and the team adapts to the changing product requirements dynamically.

The product is tested very frequently, through the release iterations, minimizing the risk of any major failures in future. Customer Interaction is the backbone of this Agile methodology, and open communication with minimum documentation are the typical features of Agile development environment.

A completely independent operating component is made after completing iteration. Iteration must not take more than two weeks in order to complete the code. Agile methodologies invite the developers to build involved with testing rather than an individual quality assurance group. Agile Development Models are best suited in evolving conditions due to new methods and principles that allow a team to build up an item in a short period.
