Choosing the right methodology for your projects is the key to success. Each methodology has its advantages and limitations in terms of the efficiency of the processes, effectiveness of its controls to deliver the projects successfully. 

Sometimes you can plan to include a combination of 2 or more methodologies and implement that in projects for successful completion. The project management is the subject that emphasizes on how to manage the projects to produce products or services as per the requirements of the customer. Implementing the right set of methodologies on the projects provides the key to competitively finish the projects and stay ahead of the competition in the market.

What is Agile 

Agile is a method of software development that is iterative and delivers the requirements incrementally instead of all at once at the end. The agile methodology work on the agile manifesto that was developed by the leading experts that tell us what approaches will work for software development and what approaches do not work. 

The agile method is disciplined project management principles and concepts that promote adaptation and inspection at every stage of the cycle. It encourages leadership philosophy, teamwork, accountability, and self-organization with the best set of engineering practices that helps in the delivery of rapid delivery of high-quality software and the business advancement that focuses on the development that provides the customer needs and the company goals.

What is Scrum 

Scrum is the part of the agile process framework that is widely used in software development. The scrum framework uses the development cycles called sprints. It is a lightweight process framework that means the overhead is kept very low so that there is no much wastage of time to get the work done.

The scrum processes are different from other agile methods on some of the concepts and principles that are divided into three categories of artifacts, roles, and time boxes. Scrum is again the incremental and interactive practices to manage complex and large project management. Scrum improves productivity and reduces the time required to produce goods or services. It is used to rapidly adjust smoothly to changes to produce the products that meet the organizational needs.

  • The benefits of agile scrum processes are as follows,
  • Enhance the quality of the deliverables
  • Able to adjust to the changes
  • Estimation is easy and better and less time is required for the same
  • There is greater control on the project schedule

What is Lean 

Lean is a concept, principle, and tool that prevent wastage in every stage of the development of the products or services. It is used to increase the process velocity and maximize the value to the customer, by minimizing all kinds of waste.

  • A lean organization has the following key characteristics,
  • To think of all the problems and errors as the opportunity for improvement of the processes
  • Derive value to the customers by minimizing the wastes in every stage
  • It promotes the culture of value addition, problem-solving, and open communication at all levels of teams in the organization that values the time invested by the employees and generate value culture in the employees.

8 wastes are described in the lean method, those are as follows,

1. Over-processing

2. Overproduction

3. Waiting time

4. Defects

5. Motion

6. Transportation 

7. Inventory

8. Unused talent

These 8 wastes must be either minimized or eliminated for the processes to be efficient and effective.
