agile vs waterfall project management

What is the Agile Development Method?

Agile is the umbrella term that refers to fluid project management methods. 

In some certain industries, a project can last months or years. But during these times, new market trends emerge and user demands also change accordingly. Therefore, companies confront the high risk of failing because their products or services hardly catch up with ever-changing user needs.

So Agile was developed to help businesses promptly respond to changes in direction and requirements even late in the process. To do so, Agile teams conduct projects over an iterative agile sprint cycle of development by flexibly prioritizing and building essential features. and making frequent deliveries. They then integrate feedback from stakeholders (e.g. real customers or business people) and make frequent deliveries to meet changes. 

There are many lightweight frameworks (e.g. Scrum, Kanban, or Spotify) you can apply for Agile projects. Each of the frameworks has a slightly different mechanism of action. Meanwhile, Agile acts as a philosophy to strengthen such frameworks and make them work better in the agile world. 

Today, Scrum accounts for 78% of companies using Agile, because of its easy application.

Pros of Agile Project Management

  • Short-term deadlines allow team members to estimate which tasks they can handle within each iteration, hence promoting their performance and morale. 
  • Members are flexible to changes because Agile allows them to receive feedback and make continuous releases. 
  • Time to market is fast because teams first produce MVPs that contain the most basic features and then make frequent releases based on user responses. This also helps teams focus more on a product’s core values. 
  • Agile encourages communications between developers and stakeholders throughout the iteration. Accordingly, development teams can identify problems early and share work progress while stakeholders can contribute their ideas during the work.

Cons of Agile Project Management

  • The project timeline is hard to define because its final outcomes depend much on market changes. If user demands constantly change, the project can last more than estimated.
  • Agile has no well-defined processes or tools. So newcomers in this domain may get the wrong way to become truly agile. 
  • Agile teams can be demotivated if they miscommunicate right at the beginning and choose redundant features to develop.

What is the Waterfall Development Method? 

what is the waterfall development method

Contrary to Agile, Waterfall better suits hands-off projects and companies where changes are negligible. Besides, Waterfall teams often follow the sequential process of development. In this process, they will accordingly define documents, expectations, and final products from scratch. 

Waterfall is the most common model of traditional project management. One noticeable feature of the Waterfall development method is that one stage’s work depends on the deliverable of the previous phase.

Pros of Waterfall Project Management

  • Waterfall teams work on a solid project plan from scratch to end.
  • Waterfall allows team members to determine clear project requirements early, hence saving time for frequent coordination
  • Having deliverables required to advance towards the next phase makes the work more systematic and structured.

Cons of Waterfall Project Management

  • No changes can intervene in Waterfall. This makes teams unlikely to adapt faster to unpredictable changes than rivals. And consequently, they may fail to satisfy end-users. 
  • Due to the linear nature, Waterfall teams cannot revisit a stage once it wraps up. If they want to make any changes, they have to come back to the first stage. But this proves time-consuming and costly.
  • As one stage depends on the previous one, any incurred problems (e.g. missed deadlines or technical debts) can have profound influences on subsequent products. Accordingly, teams have to solve the issues before the project can continue moving forward.

Comparison Between Agile vs Waterfall Project Management

Above all, the summary table below will give you a thorough understanding of the major differences between Agile vs Waterfall project management.

Comparison Factors Agile methodology Waterfall methodology
Approach Iterative  Linear
Scope Any size with a well-defined scope Small to medium scope
Planning Low-level High-level
Preferred organizational structure Multi-disciplinary, self-organizing team Hierarchical structure 
Project timeline Flexible because Agile teams can frequently produce improved releases of working software Fixed
Approach to identify need-doing tasks Critical Path Analysis (CPA) Review and retrospective
Progress control Burndown chart Earned value management
Involvement of Stakeholders Stakeholders (e.g. business people and customers) get involved in different iterations to provide feedback.  User feedback or the product owner’s involvement is excluded from the process until the work is completed.
Communications Frequent communications through daily meetings and communication tools. Accordingly, stakeholders can contribute their ideas whereas other members can understand requirements and track their progress.  Fewer communications are required in Waterfall methodology because it involves a low level of collaboration with stakeholders.
Project manager (PM) roles PMs set up plans, manage progress and follow up on tasks throughout the project. PMs, mostly called Scrum masters, act as facilitators who clear impediments and ensure all requirements are understood to get the work done well. 
Flexibility High Low
Budget Flexible because it depends much on changes of direction and adaptation Fixed because parameters and goals are clear at the beginning of the project and no extra requirements can interfere halfway

Hybrid, the Perfect Combination of Agile and Waterfall

Project Management Institute first mentioned the term “Hybrid” when learning about how companies selected between Agile vs Waterfall project management in 2015.

Hybrid project management is a blend of more than one approach to plan, monitor, and execute projects. But on most occasions, Hybrid is understood as the combination of Agile and Waterfall approaches. That is, it’s the process of using Waterfall to conduct different project phases in which tasks will be carried out in Agile ways. 

The 2019 HP online survey concluded that 24% of development and IT experts were using Hybrid for their projects. Over the past 5 years, Hybrid project management (Hybrid PM) has been also developing and becoming one of the top trends in the software segment. According to the 2021 Project Management Interview of Teamhood, this method continues to be a common norm for some following benefits:

  • Hybrid PM can be applied in projects with any scope or size;
  • A project manager builds and monitors tasks. But that PM still gives team members space to be self-organized and collaborative to get jobs done during an iteration; 
  • Internal and external stakeholders engage in the workflow but not daily.

Major Factors to Consider When Choosing the Right Method for You

major factors to consider when choosing the right method for you

Although Agile is on an accelerating trend, it doesn’t mean your company should adopt the method. Leaning towards any method (i.e. Agile, Waterfall, or Hybrid) without careful thought can result in bad outcomes. Therefore, you should ponder several major factors to find the best option for your business:

  • Are projects bound by strict requirements? In Waterfall, deliverables are required to carry out the next phase while team members need to follow a strict procedure to get jobs done on time. Meanwhile, plans and input parameters in Agile are likely to change based on stakeholders’ feedback.
  • Are projects susceptible to changes? Waterfall is best suited for projects in which requirements are fixed and no significant changes can interfere. Meanwhile, Agile is mainly designed for ongoing projects or projects going through predictable changes.
  • Can product owners and other stakeholders engage in the process? Agile is a customer-centric, adapt-to-change approach, so it allows frequent conversations with stakeholders. Meanwhile, Waterfall shows opposite patterns. 
  • Do projects require high-level or low-level team coordination? Waterfall is a more methodical form of project management that determines every requirement in the beginning. So low-level team collaboration is required. Meanwhile, Agile teams need regular communications to respond faster to new situations.

In addition, Hybrid has recently emerged as a new candidate in the battle between Agile vs Waterfall project management. But Hybrid PM itself has different pros and cons you factor in before deciding whether it’s the best bet for your company. 

In short, through this article, Designveloper expects you to have a comprehensive insight into common PM solutions. The choice of suitable PM methods is of strategic significance to any company because the chosen method will come with your projects for a long time. So picking up the proper one requires much effort and dedication right at the beginning.
