For companies to achieve goals and planned results within a defined schedule and a defined budget, most managers use a methodology which helps them smoothly carry out the project. Regardless of field or trade, there is an assortment of methodologies available to help managers at every stage of a project; right from initiation to implementation and finally to closure.
Ideally, a methodology is a model which project managers employ for the design, planning, implementation and achievement of their project objectives. Depending on the type and nature of the project, there are different methodologies which can be used. Choosing the right method for the right project is of utmost importance for the success of any project.
Project methodologies are not tool-specific, however in today’s software-reliant world the reality is that the methodology and the organization’s project management software tool are too often heavily intertwined. Some of the popular types of software development methodologies are listed here:
Agile software development methodology is for a project that needs extreme agility in requirement. The key features of Agile are its short-termed delivery cycles, agile requirements, dynamic team culture, less restrictive project control and an overall emphasis on real-time communication.
Waterfall software development methodology is a legacy model for projects. This method has been in practice for decades before the new methodologies were introduced. In this model, development lifecycle has fixed stages and linear timelines. The model is not capable of addressing the challenges in the modern software development domain, and is only used for very linear and short-termed projects.
Scrum is a type of Agile methodology that focuses on 30-day sprints where project deliverables are broken down into 30-day intervals. In scrum, there is no project manager. Instead there is a Scrum Master whose role is to facilitate the daily project communications and tackle any distractions that are trying to interfere with team member’s ability to work on the project.
This is a method for managing projects used by the UK government and characterized by a product-based planning approach. In PRINCE2, high level activities such as setting business justification and resource allocation are owned by a structured project board while a project manager takes care of the lower level, day-to-day activities such as scheduling.
This is a statistics-based methodology that seeks to improve the quality of a process by measuring the defects or bugs present and getting it down as close to zero as possible. A process can therefore attain a rating of Six Sigma if 99.99966% of the final product is defect-free.
Rapid application development methodology focuses on developing products faster with higher quality. When it comes to gathering requirements, it uses the workshop method. Prototyping is used for obtaining clear requirements and the re-use of software components is encouraged in order to accelerate development timelines. In this method, all types of internal communications are considered informal.
This is a step-by-step methodology used for projects with interdependent activities. It contains a list of activities and uses a work-break-down structure (WBS, which is a timeline to complete dependencies, milestones and deliverables. It outlines critical and non-critical activities by calculating the “longest” (on the critical path) and “shortest” time to complete tasks so as to determine which activities are critical and which are not.
This methodology focuses on the use of resources within a project instead of project activities. To address potential issues with resources, buffers are built so as to ensure projects are on-time and that overall safety is not compromised.
The spiral model is a risk-driven process model generator for software projects. Based on the unique risk patterns of a given project, the spiral model guides a team to adopt elements of one or more process models, such as incremental, waterfall, or evolutionary prototyping.
An iterative model does not attempt to start with a full specification of requirements. Instead, development begins by specifying and implementing just part of the software, which can then be reviewed in order to identify further requirements. This process is then repeated, producing a new version of the software for each cycle of the model.
The incremental model is a method of software development where the product is designed, implemented, and tested incrementally until the product is finished. It involves both development and maintenance. The product is defined as finished when it satisfies all of its requirements.
The evolutionary software development methodology is based on the idea of rapidly developing an initial software implementation from very abstract specifications and modifying the same according to your appraisal. Each program version inherits the best features from earlier versions. Each version is then refined based upon feedback from yourself to produce a system which satisfies your needs.
After choosing the right project methodology companies need to follow a structured process in order to ensure the success of the project. Most companies follow this 4-step cyclic approach during project execution:
This step is essential as it helps gather information on the specific business needs of the customer. Consultation sessions are held where the team learns about the client's goals, scope, expectations, business practices, existing resources and budget. These sessions are also used to showcase the company’s offerings, share past experiences and provide information on the various industry trends.
This step deals with the presentation of the proposal to the client. The proposal contains the various aspects of the project like planning, execution, delivery, software processes to be followed, SDLC methods, communication, timeline, resource allocation, licensing and intellectual property ownership, post-delivery support and maintenance, foreseen hurdles and uncertainty, warranty, technology to be used, etc.
This necessary step deals with the details of the proposal. Various aspects of the contract like confidentiality agreements, service level terms, taxes, working procedures and legal arbitration are discussed and agreed upon. The service provider always makes sure that all contracts are flexible and scalable to allow for changes and updates to the project as they work on it.
During the execution stage, the business solution is developed according to pre-agreed terms and conditions. Regular review meetings are conducted to oversee the execution of the project. Project execution is usually phased out and delivered in parts.
In order to keep to the high quality standards, companies ensure that the cycle of Consultation, Proposition, Confirmation and Execution is repeated after each delivery is made.
