The History of Professional Scrum Master (PSM)

Codes are the integral elements of a software. Codes can be written in a number of programming languages like C, CPP, JAVA, VB etc. The output obtained after the execution of a given code is a “software”. Software is always developed as per the client’s need. Once the software gets ready, it is first tested before deployment is done.

For any software, Testing is the fundamental step to use the software successfully. Testing is the process of evaluating a system or its component(s) / parts to satisfy all product requirements. According to ANSI/IEEE 1059 standard, Testing can be defined as ― “A process of analyzing a software item to detect the differences between existing and required conditions (that is defects/errors/bugs) and to evaluate the features of the software item”. Collectively, this is called Software Development.

The main objective of Software Development is to produce ‘high quality software’ that meets the customer requirements. This process of developing a software and finding the bugs is called as Software Development Life Cycle (SDLC). SDLC is a process followed for a software project, within the same organization. It consists of a detailed plan, which describes how to develop, maintain, replace and improve a software. The life cycle defines a methodology for improving the quality of software and the final development process. The following diagram describes how SDLC works.

Agile is a general approach to software development. All agile methods including Scrum, focuses on teamwork and the frequent deliveries of quality software. They also render the ability to upgrade according to varying customer requirements.

Scrum is one of the commonly used process of Agile software development. Agile and Scrum are closely associated. Let me give you an instance. To purchase anything, you can directly visit a shop. There, you get a wide range of brands. But you select only the ones you like the most. In a similar way, Scrum is the brand for Agile.

Typically, all the processes in Agile use Scrum. Nowadays, Scrum is just another trend for organizations. Scrum has been there since 1986. The first paper on Scrum was published in the Harvard Business Review in January 1986. The popular Software teams started using the Scrum agile process in the year 1993.

Need for Scrum Certifications:

As per the demand of Scrum methodology, new certification courses are being developed. These help you become a Scrum Master. A sound understanding of the values of Scrum is mandatory. This amplifies your potential to become a Certified Scrum Master (CSM) and a Professional Scrum Master (PSM).

Ken Schwaber initially designed the CSM course in 2002. Thereafter, he introduced the updated version of CSM in 2009. This updated version is known as Professional Scrum Master (PSM).

Professional Scrum Master encompasses the basic and advanced concepts of Scrum. You also learn how to implement this knowledge in real-world situations. The Professional Scrum Master certification proves to be equally effective for experienced Scrum Masters and Advanced Practitioners.
