Why Waterfall methodology is most appropriate for a point-of-sale system project-

First, we need to know this:

The waterfall model is a classical model used in the system development life cycle to create a system with a linear and sequential approach. It is termed as a waterfall because the model develops systematically from one phase to another in a downward fashion. This model is divided into different phases and the output of one phase is used as the input of the next phase. Every phase must be completed before the next phase starts and there is no overlapping of the phases.

A point-of-sale system, or POS, is the place where your customer makes a payment for products or services at your store. Simply put, every time a customer makes a purchase at your store, they are completing a point of the sale transaction.

1. In the point-of-sale system project the all the requirements are clearly known as everyone is using the same kind of software for many years.

2. In the point-of-sale system, each function is defined for its work, even we can add/ delete more functions further.

Role of Project Sponsor-

The role of the project sponsor is vital. It is too hard to find a good sponsor for your project. The sponsor gives you the money for your resources, like- salary to the employee can be given if any startup is getting sponsors.

Example- If I want to start a content channel for tutoring, I will need a sponsor who can provide me some essential things which I can use in content creation. In return, the sponsor gets moneyback and royalty.

Role of the Business analyst-

The Business analyst is the person who has professional skills o bring the business to the company. he reads the market for your product.

Role of scrum master-

A Scrum Master leads a scrum. Scrums are daily meetings conducted by Agile, self-organizing teams that allow the team to convene, share progress, and plan for the work ahead. Some teams have a fixed Scrum Master, while others alternate the role with various team members occupying the position on different days. No one approach is right, and teams can choose to appoint the Scrum Master role as best fits their needs.

During the daily meetings, the Scrum Master asks the team members three questions:

1. What did you do yesterday?
2. What will you do today?
3. Are there any impediments in your way?
