Advantages and Disadvantages- Scrum Vs Waterfall

When you take any kind of project in hand, the question is which methodology you will use for your project? Will you opt for Scrum Vs Waterfall Scrum/ Agile or go for Waterfall? This is decided by the project type itself.

Both Scrum as well as Waterfall has benefits as well as drawbacks.  Hence, both are equally in demand.  Here, in this blog; we will take a look at the advantages and disadvantages of Scrum Vs Waterfall.

Advantages and Disadvantages of Scrum Vs Waterfall:

Waterfall:

Advantages:

In this project methodology, work is done step by step where every part of work is done in small steps. Once one phase is finished, the project then moves to the next phase. Numbers of phases vary according to the methodology chosen.

Like as, when you choose Waterfall methodology, the project phases may increase or decrease as compared to Scrum methodology and vice versa.

Advantages of Waterfall: 

• Easy implementation of forward and backward planning.
• Visible output at every stage – This can lead to better visibility. It includes a baseline to move forward on.
• Choose a target delivery and end date based on the scope of the project.

Disadvantages of Waterfall:

-        

•   If the project scope changes, it can impact the quality of the project.
•  If the tasks are not done properly and if the mistakes are found at the last stage, complete project can be impacted.
• If the project is dependent on internal or external resources, it can lead to delays as the “plan” is already written. 

Well, this was about Waterfall. What is about Agile/ Scrum?

Agile/ Scrum Methodology

It is a type of process where everything required to complete a project is done parallel. There are different Agile frame works, each of them has the similar empirical structure where the tasks are divided into small subparts.

Requirements and solutions keep on changing based on project priority.

Agile Advantages: 

      a)      Change- Requirements keep on changing. Agile can quickly cater the changes for shorter planning cycles.

     b)      Active Involvement:  This project methodology always boosts the active involvement as well as interaction from the stakeholders that is useful to build product depending upon the accuracy and privacy.

     c)       Team interaction:  In Agile methodology, there’s constant team involvement and structured communication channels which help in the progress discovery, their impediments and collaboration.

     d)      Constant improvement:  At one phase, lessons learnt are useful to improve further steps.

Disadvantages: 

• Planning becomes difficult at times because requirements keep on changing. Hence, long term planning never serves the purpose.
• There’s a continuous need for time and efforts. This is important to planning the cycle as well as success.
• Agile has unique and alternative approach. Hence, for projects with a different approach, training is required. 
• The teams must be experienced and skilled enough to deal even with the toughest projects.

Based on these advantages and disadvantages of both the methodologies you can choose the best suitable approach depending on the delivery type, structure of the organization and resource accessibility.

In a nutshell:

Both the approaches can be blended together, i.e. Agifall and Wagile. These blended in Scrum Vs Waterfall approaches are becoming popular today and are becoming much more common in today’s global organizations.

Scrum Vs Waterfall - How to Compare?

Scrum Vs Waterfall - The comparison varies from person to person. It differs as per the views of the person. In real IT industry, very few actually work using pure Water fall. It has many variations. Still, some thoughts that occur to me are as follows:

Scrum Vs Waterfall:

• Scrum has a prioritized product backlog from which one can execute Pareto rule. WF tends to assume 100% rule. It also tends to order the building of the product mainly because of technical dependencies.

• Scrum usually uses adaptive planning whereas Waterfall tries to stick to the initial plan. When using Scrum, one can get the feedback easily from the working software whereas in Waterfall, it doesn’t have working software until it’s late in the entire developmental cycle.

• Waterfall assumes that everything is known beforehand where as Scrum assumes there’s a lot that is yet to be known. It focuses on increasing the learning throughout the project.

• Waterfall tries to reduce the change whereas Scrum tries to increase the benefits of good change eg : learning and reduces the effect of negative change.

• Scrum assumes that change is normal and most of it cannot be controlled usefully. Waterfall thinks that change is bad and can be controlled.

• Waterfall, on the other hand, puts more responsibility on the project manager whereas in Scrum, team has the maximum responsibility. Waterfall uses a diffuse work group with only PM and its overall responsibility.

• In waterfall method, the project manager should plan the work and in Scrum, the team must plan the work. In case the plan fails, the team can then replan the work.

• Waterfall presumes that planning must be done from the center i.e. by the PM and the workers must execute the work that they are given.

• In Scrum, the team must organize its work on its own and make the use of the approach ‘full complex adaptive system”. It optimizes business value, time to market and quality. Waterfall optimizes the budget.

• People using Waterfall method for managing the projects, always think that if worked as per the plan, everything will go well and those using Scrum for managing the projects, think that they must rethink for themselves in every specific situation.

• It is a base framework of things that are essential for every effort. In Scrum, must always be done. Those professionals who are really “professional” use agile scrum ideas while managing the project.

In a nutshell:

The ideas and practices of Scrum Vs Waterfall are constantly in debate. These remain in real practice, boost progress as compared to Agile. All the above statements are based on the personal experience.

Other variations are always welcome. You can also share your ideas about Scrum Vs Waterfall with us. Let us know what you prefer the most and why. To get the accurate methods of project management, you can reach out to Lean agile training.

Get in touch to discuss ideas briefly. We love to share and accept ideas about any new or the currently in trend project management method.

Scrum vs Waterfall Model Pros and Cons

Scrum vs Waterfall

Since the change in the process of using your business, its setting may seem like a difficult task, but it is fine that Blue Warren has returned in June 2016 Scrum vs Waterfall. However, a new piece of software was slightly darker than switching just a chain-of-command; It demanded to change our entire methodology in Scrum vs Waterfall.

Before then, Blue Warren used the project for the fall of the spring, but the number of reasons for the switch on the scrape became increasingly clear. With some teams, we have to talk about some changes and talk about changes, and discuss how they felt about the switch in Scrum vs Waterfall:

When did you first hear about the Scrum vs Waterfall?

PH: 17 years ago, from Lancaster Uni, Ian and his software engineering course. Script framework is born from software engineering.

DM: In my course there were specific modules about tight methods with emphasis on scraps.

ML: My wife bought me: The art of working half-time for my birthday by founder Jeff Sutherland. I started reading it on vacation and was tilted.

SD: When Michael and Phil gave me a Scrum book and said, read that for Scrum vs Waterfall!

So, why did you switch in Scrum vs Waterfall?

ML: The approach makes much sense.

SD: After reading only the first few chapters, I bought it in direct consideration and started implementing it. I was not happy with the process at that time and felt that this is a better way for Scrum vs Waterfall.

DM: On software, we wanted to improve the distribution speed of projects.

SQ: We needed better cooperation. The Scrum allowed everyone to include their thoughts, and prevented people from sitting on the information that other people could be helpful.

PH: We thought about how this can be used only for more than software engineering, and how collaborative, transparent and fast-paced nature can lend itself to any project, through the repetition process Tight control is required in Scrum vs Waterfall.

ML: Scam forced the discipline of total engagement and transparency among all the team members and customers every day. It gave ownership of the project to each person and enabled us to respond promptly to any issue, thereby creating no obstruction in the project.

What was this appealed in Scrum vs Waterfall?

ML: The original appeal was the concept of Daily Stories where we will understand the role of Scrum Master and product owner along with the health of each project in the business - help them clarify the obvious responsibilities within the team.

EL: For me, this was the organization and structure. The full visibility of all the ongoing projects in Scrum Master Certification Course and Certified Scrum Master Workshop is good, and it helps to see what other people are working to avoid blockages.

DM: Besides, it has tried and tested. It enhances communication and opens the ability to share ideas.

SD: I love the team's work and the idea that we all are equal and take charge of the project. Everything is transparent.

PH: Yes, transparency for the team, accountability, team wins or any win ... The eternal knowledge that you collect in the projects you get every day is invaluable.

SQ: Better transparency between project groups and customers. In theory, it gives them an accurate time frame and a better estimate, which makes them happy - which makes us happy Scrum vs Waterfall.

Scrum Vs waterfall Project Management Methodologies

Scrum Vs waterfall

 

When you invest in project management training, you will be familiar with key project management practices Scrum Vs waterfall. Learning about these methods will enable you to organize your project effectively, which will focus your strategy and enable you to achieve good results. Here are just a few key PM practices:

Waterfall

This method is well-known in most industries and is especially popular in the construction industry. There are many different versions of this process with the original version,

Including these key steps for Scrum Vs waterfall

1. Alignment of elements

2. Design

3. AK or Coding

4. Integration

5. AK validation

6. Installing

7. Maintenance

PER (enable packaged re-engineering)

In most modern PM courses, this method cannot be mentioned, but it is still commonly researched because it follows conventional and traditional avenues for project management. Longer papers on procedures explain deeper theories and applications that can be applied in conjunction with other processes.

NPI (new product introduction)

NPI is not considered a complete method because PMM lacks complete process (and steps) to plan for success, but it is still a useful process that businesses and companies use in relation to products related to products.

SCRUM

In Scrum Vs waterfall Scrum is a different method (compared to more traditional types) that does not use traditional terminology or standard PM Framework. It works in projects that are not widely restricted by budget or time frame and call for a whole dedicated team at the same time, with members who can work on different projects. In this process, the project manager will be called 'Scroll Master', whose main responsibility is focusing in the team, eliminating any distraction and encouraging and facilitating good communication in the team.

The process involves a 30-day cycle labeled 'Sprint' with 'Scrum Sessions' per month. Targets and timelines have broken into 30-day schedules which means that teams struggling to organize most complex projects or their workloads can benefit from the process.

Red (Rapid Apps Development)

The software development sector uses this PM system frequently because it uses collective techniques and modeling to determine the client's requirements and to successfully make and improve the final system in Scrum Vs waterfall. The methodology uses a model and a continuous series of techniques within the processing project. Although some managers do not favor the original method because they believe that the original processes are not sufficient enough to create complicated efficiencies, newer versions are to solve these issues, which means that it has become a more efficient and useful method in recent years.

PRINCE2

PRINCE2 is perhaps the most popular word used in terms of project management. It is an influential standard in the public sector and at the same time there is a method in Scrum Vs waterfall. Instead of a recommended 'good practice' or strategy, PRINCE2 is known by the UK government (and used by them) and is used worldwide. Whether PRINCE2 is a good approach to your organization, it really depends on your industry but it is very effective in effective project management training and supported by the appropriate PM framework.
