Software development processes are always evolving, and different approaches have emerged over time, with their unique strengths and weaknesses. Two prominent software development approaches are the traditional plan-driven (waterfall) approach and the agile SCRUM framework. One of the fundamental aspects of software development is the requirements analysis process, which involves gathering, documenting, and managing stakeholders’ needs and expectations. In this paper, we will compare and contrast how the requirements process and how requirements are documented differ between the traditional plan-driven software development approach and the SCRUM framework. We will also examine how changes to requirements are handled within each approach.

Description:

The traditional plan-driven software development approach follows a sequential process, where each stage of the development cycle is completed before moving on to the next stage. This approach requires extensive documentation, including detailed requirements specifications, design documents, and test plans. The requirements analysis process typically involves a thorough exploration of the stakeholders’ needs, expectations, and preferences, with an emphasis on defining the system’s expected behavior. The requirements are documented in detail in a project plan, which serves as the basis for the subsequent development stages.

In contrast, the SCRUM framework is an agile approach that emphasizes flexibility and adaptability. The SCRUM process involves iterative and incremental development, where development occurs in short periods called sprints. The requirements analysis process in the SCRUM framework is less detailed than in the traditional approach. The focus is on developing a product backlog, which is a prioritized list of features that the product owner wants to include in the final product. The backlog items are high-level descriptions of features or functionality that are continuously refined throughout the development process.

Changes to requirements in the traditional plan-driven approach require a formal change management process. Changes must be documented, reviewed, and approved at each stage of the development cycle. The documentation update may require reworking the design and test plans, adding time and cost to the project. In contrast, the SCRUM framework accommodates changes to the requirements at any point in the development process. The development team collaborates with the product owner to refine the product backlog continually. The changes are incorporated into the product backlog for prioritization and implementation in the subsequent sprints.

Conclusion:

In conclusion, the traditional plan-driven software development approach and the SCRUM framework differ in their requirements analysis process and how requirements are documented. The traditional approach emphasizes detailed documentation, while the SCRUM framework prioritizes flexibility and adaptability. Managing changes to requirements also varies between the two approaches, with the traditional approach requiring a formal change management process while the SCRUM framework accommodates changes through product backlog refinement. Software development teams, project managers, and stakeholders must carefully consider each approach’s benefits and drawbacks and select the one that best suits their needs.

Introduction:

The requirements process is critical to the success of any software development project. It specifies the needs, expectations and constraints of the customers and stakeholders and guides the development team regarding the acceptance criteria of developed software. In the traditional software development approach, the requirements phase is usually the first phase, and it is the lengthiest. While in the SCRUM framework, requirements are defined to some extent initially and are further developed in iterations.

Requirements Process in Waterfall vs. SCRUM:

In the Waterfall model, the focus is on accurately capturing the requirements at the beginning of the software development life cycle. Requirements are collected in the initial phase, documented explicitly, and then used as a roadmap for the whole software development lifecycle. This is known as a “Big Design Up Front” approach. Any changes in the requirements after the closure of this phase are handled formally, through a Change Control Board (CCB), which evaluates the effect of the change on the subsequent phases. In contrast, the SCRUM framework incorporates an iterative and incremental approach to software development. Requirements are captured in high-level form and sliced into user stories that are prioritized in the backlog. The requirements continue to evolve as the product owner reprioritize the stories. In SCRUM, the development team manages requirements and deemed to manage changes formally at the sprint review meetings.

Documentation of Requirements in Waterfall vs. SCRUM:

In the waterfall approach, documentation of requirements is comprehensive and detailed. It consists of several documents that could include product requirements document, functional requirements document, software specification, and design documents. In contrast, requirements documentation in SCRUM is much simpler. Agile methodologies stress on “working software, over comprehensive documentation”, focusing on tangible outcomes instead of the documentation itself. This does not suggest that no documentation is needed, but it is essential to keep the documentation lean and focused to meet project requirements.

Changes to Requirements in Waterfall vs. SCRUM:

In Waterfall, changes to requirements are not easily allowed after the completion of the requirements phase, and a formal change request is needed for any change. This is due to the fact that changes in the requirements at the later stages would result in implications throughout the development phase and the increased costs involved in fixing the software. On the contrary, change is expected in the SCRUM. The agile approach permits late changes in the project scope during any sprint, provided they are in line with the original project goals.

Conclusion:

In conclusion, both traditional plan-driven (waterfall) software development approach and the agile (SCRUM) methodologies have different approaches to requirements gathering, documentation, and changes management. Waterfall emphasizes a formal approach to requirements documentations which are detailed and fixed, while SCRUM focuses on simplicity in documentation and is adaptable to changes. It is essential to understand these differences to select the best approach for managing the project requirement based on its specific needs.

Solution 1: Traditional Plan-Driven Approach

The traditional plan-driven or waterfall software development approach involves sequentially following different phases such as planning, analysis, design, implementation, and testing. The requirements process in this approach starts with gathering and documenting all the requirements at the beginning of the project. These requirements are then frozen, and any changes later in the development process require formal approval, documentation, and a change request process.

Requirements are documented in a detailed document called the Software Requirements Specification (SRS). The SRS includes all the functional and non-functional requirements, system design constraints, and other details that are necessary to develop the software. This document serves as a reference during the entire development process and is used to ensure that the final product meets all the initial requirements.

Any changes to requirements in the plan-driven approach require a formal change request process. The changes are evaluated for their impact on the cost, schedule, and other project constraints. Once approved, these changes are documented, and the SRS is updated.

Solution 2: SCRUM Framework
The SCRUM Framework is an Agile software development methodology that emphasizes collaboration, flexibility, and the ability to respond to change quickly. The requirements process in SCRUM is different from the traditional plan-driven approach.

In SCRUM, the requirements process starts with creating a prioritized list of product features, called the product backlog. This list is continuously refined and updated, with the product owner taking feedback from the stakeholders.

The requirements in SCRUM are documented in a lightweight form called user stories. User stories capture the users’ perspective and describe the functionality of the system in a simple language that is easy to understand. Each user story is estimated by the development team to determine how much work is required to implement it.

Changes to requirements in SCRUM are embraced as a natural part of the software development process. The product backlog is flexible and can be reprioritized, and new items can be added or removed easily. The development team is empowered to change the requirements if needed, with the feedback of the product owner.

Conclusion:
In conclusion, the requirements process and documentation differ significantly between the traditional plan-driven approach and the SCRUM framework. The traditional approach prioritizes upfront documentation, with detailed SRS written at the beginning of the project. In contrast, SCRUM emphasizes collaboration and flexibility, focusing on the prioritized product backlog and user stories. Changes to requirements are also handled differently in each approach, with the traditional approach requiring a formal change request process, while SCRUM embraces changes as a natural part of the software development process and allows the development team to change requirements if needed. Ultimately, it is up to the organization to choose the approach that best suits their needs and context.

Introduction:
Software development process is an extensive process that needs to be appropriately managed to produce high-quality software products. The traditional plan-driven (waterfall) and agile development methodologies are prominent approaches used for software development. The requirements process and how the requirements are documented differ between the traditional plan-driven (waterfall) software development approach and the SCRUM framework. This article will compare and contrast how the requirements process and how requirements are documented differ between the traditional plan-driven (waterfall) software development approach and the SCRUM framework. It will also discuss how changes to requirements are handled within each.

Traditional Plan-Driven (Waterfall) Approach:
The traditional plan-driven (waterfall) approach is a more formal and structured approach to software development, where the requirements are gathered at the beginning of the project and are documented in a requirements document. The focus is on planning, design, and construction phases, which are carried out sequentially. Once the requirements are defined, there is no room for changes, and if they do arise, they are documented as change requests and then have to go through a change control process.

SCRUM Framework:
The SCRUM framework is an Agile methodology that follows a flexible approach to software development. It is a collaborative approach where teams work in sprints to deliver functional software. The requirements process in the SCRUM framework is continuous, and requirements are gathered and refined in each sprint. There is no formal requirement document, but requirements are maintained in a product backlog.

Comparison:
In the traditional plan-driven (waterfall) approach, the requirements are gathered at the beginning of the project, whereas in the SCRUM framework, the requirements are continuously gathered and refined in each sprint. In the traditional plan-driven approach, the requirements are documented in a requirements document, while in the SCRUM framework, the requirements are maintained in a product backlog.

Changes to Requirements Handling:
In the traditional plan-driven (waterfall) approach, changes to requirements are managed through a formal change control process. The changes are documented as change requests, and then the change control board approves or rejects them. In contrast, in the SCRUM framework, changes to requirements are handled through continuous collaboration between the development team and the product owner. If the development team discovers new requirements during a sprint, they are added to the product backlog, and the product owner prioritizes them.
