What is Waterfall Methodology? Various Stages of Waterfall Project Management The waterfall model follows five to seven phases rigidly in a linear order.
The linear phases described in the waterfall model are: Requirement Analysis The critical aspect of the waterfall is that managers gather all customer requirements and documentation at the beginning of the project. Design The design phase is segmented into two subphases: logical design and physical design.
Implementation The implementation phase is when all the team members put all the plans into action and start the actual project execution. Testing In this phase, all the development elements of the execution stage are tested. Maintenance This is the ongoing stage, where a group or a specific team member is constantly in touch with the client and provides maintenance support on the product or service.
What is Scrum? Scrum Master The Scrum Master assists the team to accomplish the best results. Scrum Team The Scrum Team comprises five to seven professionals with technical expertise. Various Steps in the Scrum process Scrum draws upon four sprint structuring events: sprint planning, daily stand-up, product backlog, and sprint retrospective.
Sprint Planning The sprint planning meeting is held at the beginning of each Sprint wherein all the team members participate, i. Daily Scrum Meetings The objective of the Daily Scrum is to evaluate the progress of the tasks until the end of the Sprint. At scrum meetings, Scrum Master addresses the following questions: What did the team members do yesterday?
What will they do today? And are there any bottlenecks or issues that need to be resolved? Sprint Review Meeting Each Sprint is an individual entity; it provides a mini deliverable of the final product.
Pros and Cons of Agile Scrum and Waterfall The benefits of effective project management are widely known: enhanced client satisfaction and excellent results delivered on time and within budget. This makes the deliverables of all stages more straightforward.
The waterfall model works well for small projects where project scope and requirements are well-defined at the initiation stage. Customer or client presence is not strictly required during the execution stage except for project reviews, critical approvals, status meetings, etc.
It possesses a process-oriented framework with less dependency on individual team members. The cost of fixing any failure or issues in the functionality is very high.
It also negatively impacts the project quality and causes delivery delays. The waterfall development approach is process-oriented, such that requests for modification at the latter stages of the development cycle are unlikely to please.
Advantages of Scrum Framework The scrum framework provides more project visibility with daily stand-up meetings. The issues are identified allowing managers to resolve them intelligently ahead of the curve. Get started. Waterfall methodology is often presented as the dragon slain by the heroic knight Agile and his faithful steed, Scrum.
On a Waterfall project, each phase had to be completed before anybody could move to the next one. Gathering the requirements had to come first, then design, development, testing, and finally release. New versions of software could take a year or more to hit the market.
This holy document proposed a new kind of project management , built around short shipping cycles, frequent collaboration with stakeholders, and the embrace of constant change. Each Scrum team would devise a product backlog list of features and requirements , then work on it in sprints, each lasting 1—4 weeks, and tackling a chunk of the backlog. And they all lived happily ever after. The Waterfall model dominated project management for eons. Can you imagine a contractor building a house in two weeks, then iterating on it while the residents lived there?
Or a farmer replanting his fields once a month, because people told him they wanted different vegetables? Agile and Scrum started out in the software industry, where teams were tackling projects that could be distributed at the speed of light.
Of course, there are other routes to Agile project management. Kanban is almost as popular as Scrum. Scrum works best on a single team of developers. The ideal Scrum team is made up of 3—9 talented, driven individuals who are great at organizing themselves.
The agile software development community primarily focuses on the self-organizing team and collaboration. This means agile teams are cross-functional. Managers still have a place in an agile model. They ensure that each team member has, or obtains, all the right skills required for the project. In an agile framework, managers work by creating an environment that brings out the best from the team.
However, instead of being at the forefront, they often step back and allow the team to determine how they will deliver products. Managers only step in when teams fail at resolving issues after multiple tries. Also referred to as a linear-sequential life cycle model, the waterfall model was the first Process Model that was introduced.
Originating in manufacturing and construction, the waterfall model was initially meant to be used in physical environments—those that are structured significantly and were not easily adaptable to changes. In the software development life cycle SDLC waterfall model, each set or stage of tasks should be finished before the next stage can begin. In waterfall project development, this is done to keep the project stages from overlapping.
Its stages include analysis, initiation, testing, design, construction, deployment, maintenance, and testing. Just like any other approach, the waterfall method comes with many benefits. For one, the stages of project planning and design are more established. With waterfall software development, customers and the development team are more in sync when it comes to project deliverables. Waterfall development also makes it easier to track progress because you know the scope of the project right away.
Rather than having the whole team prioritize one stage, the waterfall methodology enlists experts, developers, analysts, and testers to focus on their roles in the project.
Scrum is a kind of agile methodology. It is one of the process frameworks included in the agile approach. In the scrum methodology, the basic unit of development is called a Sprint. Every Sprint begins with a planning meeting in which tasks for the sprint is defined. This is also the part where the estimated commitment for the sprint goal is made.
A Sprint concludes with a retrospective or review meeting where progress is evaluated and the next sprint lessons are figured out. Meanwhile, the agile framework involves a team working through a complete SDLC. The product goes through several iterations throughout the process. Daily team meetings focus on the state of work in progress with the goal to plan the working day ahead.
This helps provide overall transparency of the project and leads to early detection of issues that need to be resolved. When everyone is on the same page it creates a level of cohesion which allows proficiency to thrive. Collaboration is key and the team works as a unit to deliver what is needed during each sprint. Scrum is all about teamwork — each team member has a specific role, yet they all work in unison with each other toward a common goal, hence the name Scrum see side note above.
With regular and shorter sprints allowing for constant feedback and greater communication, changes are able to be implemented faster. As in all teams, Scrum relies on the cohesion of each team member to serve the whole. This means that when a team operates as a single unit, they are able to work better, faster and smarter, saving time and ultimately money. Because Scrum is a subset of Agile it means that the lack of a set deadline for the completion of the project can lead to additional work being added continuously, further delaying completion.
And, as with any team relying on the strength of the sum of its parts, the commitment of the entire team to the project is paramount. If one person slips, the entire team follows suit.
So individual, as well as team commitment and focus, is of the utmost importance. So the Scrum Master has an important line to walk, to keep the team in check but also allow the team to make decisions as a whole. If you have followed everything and understood the differences between Waterfall, Agile and Scrum processes thus far, then you should already have a good idea of which approach is best suited to you and your team. If you enjoy rigid rules and structures and find that they provide clarity then the Waterfall method may be your best bet, as this is for projects with a fixed scope, deadline, and budget.
If, on the other hand, you find inspiration in the freedom and flexibility that Agile provides then that may well be where you need to focus. If, however, you prefer a bit of structure within a fluid framework then Scrum is the way to go.
But these methodologies must be weighed up against your project at hand and your desired end-goal. Contact us. Ready to defeat your tech ignorance? First things first Throughout the duration of a project, you and your team will either choose or be forced to make a series of important decisions which could affect the outcome of the entire project. What is the Waterfall method? Pros of the Waterfall method Due to its rigid, linear nature, the Waterfall method is best suited to simple, unchanging projects.
Cons of the Waterfall method The most glaring problem facing the Waterfall method is its inability to adapt to change. What is Agile? Pros of Agile The most defining aspect of Agile is that it wholeheartedly embraces flexibility, speed, and above all else, continuous improvement.
