What is Agile?

Agile is a cyclical technique used for project management & software design processes that enable teams to deliver value to clients efficiently with minimal hassles. A corporation that is agile adapts rapidly to changing markets as well as workplace conditions.  Such businesses recognize that change is unavoidable, so they assess their systems and practices on a regular basis to ensure that they have been favorable to optimal work engagement, satisfaction, and productivity.

What is Agile methodology?

The Agile methodology is a style of project management that divides a project into segments. It necessitates ongoing engagement with stakeholders as well as continual development at each stage. Teams revolve through a sequence of planning, implementing, and assessing once the job begins. Collaboration is essential among team members as well as project stakeholders.

In recent times, the usage of Agile as a project management methodology has skyrocketed. Agile development approaches will soon be adopted in 85% of any and all software creation projects, according to Gartner. It has evolved into a blanket term encompassing a number of planning, administration, and technological approaches and processes for iteratively managing projects, software development, and additional products and services. Some such examples are Scrum, by far, the most common and popular software development approach, Kanban, and XP (eXtreme Programming or Paired Programming).

Technical approaches that facilitate Automated Tests, Continuous Integration/ Seamless Delivery/ Distribution (CI/ CD), and an ever-shortening release cycle for software as well as other goods, are also included in Agile methodology. Most of these activities belong under the blanket term  – DevOps.

Similarities between Lean and Agile

Although different concepts, several similarities exist between the two methodologies, some of which are:

• According to the Lean methodology, each activity should be examined and improved on a regular basis. As a result, this strategy places a strong emphasis on continual improvement or Kaizen. Regular inspections of the outcomes and the work design are also part of the Agile approach, which allows for the evaluation of potential improvements.
• Both methodologies place higher importance on the people responsible for the project execution than the tools that are used.
• Lean as well as Agile, strive to provide more value to customers by proactively responding to client feedback or paying attention to excellence.

Differences between Lean and Agile

Let us now look at how these two concepts differ.

1. Methodology

Persistent improvement and customer satisfaction are prioritized in agile development. The Agile method uses a cyclical development process and active client involvement from beginning to end by the Agile team. The Agile method uses a cyclical development process and active client involvement from beginning to end by the Agile team.

The goal of the Lean Methodology is to reduce risk and eliminate waste. The production time reduces and increases efficiency when you eliminate everything that isn’t helping the project achieve its final aim.

2. Area of Focus

The scope of the project and the utility to the client are at the heart of agile projects. You prioritize the value proposition at the conclusion of each sprint and make improvements in the next cycle.

Lean methodology, however, is mostly about increasing process efficacy and quality. The importance of process development and quality is highlighted, with a strong emphasis on the absence of faults.

3. Structure of Teams

A team following the Agile methodology consists of a group with limited members who, generally, are:

• Self-organized: Teams decide on their own how to complete the assignment. 
• Interdisciplinary: Team members have a variety of tasks and talents, but they all work toward the same goal. 

In Lean methodology, on the other hand, several Lean teams are created, which are made up of employees from various essential areas. A ‘Team Leader’ oversees the group and solo initiatives in each group. The  Lean team participants should be competent, but they don’t require to be self-organized or interdisciplinary all of the time.

4. User-friendliness

When the needs change frequently, the Agile methodology provides better flexibility and hence may prove to be more efficient to use.

In the midst of continuous change in requirements, Lean methodology is relatively rigid and may present complexities.

5. Timeline of Projects

To accomplish tasks more rapidly, agile teams operate in short development cycles. Loops and sprints are usually 2-4 weeks long.

By optimizing process flow, lean teams can minimize the duration of the project timetable. They usually limit their labor in procedures, which reduces the project’s overall time frame. There is no predetermined timeline, unlike Agile.

6. Approach

An Agile environment enables the construction of a project in brief iterative and cumulative cycles, known as sprints. It’s a strategy of dividing any project, down into segments, each of which includes planning, execution, testing, and assessment. This is accomplished by going a single step at a time till the goal is met.

By making small, continual adjustments all through the production process, the Lean approach strives to enhance efficiency. This can result in quicker development cycles, although it is not Lean’s main objective.

Advantages of Lean

Here are some of the key benefits that you can avail by following the Lean Methodology:

• Reduced waste: Lean methodology aids businesses in determining better resource allocations in order to reduce waste, give greater value to customers, and boost profit margins.
• Better Productivity: It can help you increase the operational efficiency of your company by removing distractions and giving employees instructions that enable them to concentrate on critical tasks.
• Increased Process Efficiency: Companies that use lean methodologies can optimize their procedures by embracing the concept of pull, which involves only creating things whenever there is a market demand for them. This enables businesses to guarantee that each stage of their value chain is running well.
• Better Focus: By decreasing unproductive operations like downtime, extra inventory, and needless duties, lean methods can assist an entire organization to improve its focus. This frees up staff’s time to focus on tasks that add value to their clients.
• Reduction in Costs: The paradigm of the lean technique focuses on maximizing profits by minimizing waste and determining the greatest price consumers can justify spending for an item.
• Better Quality: Companies can increase the general value of their offerings by focusing solely on what delivers benefits to clients. They can also better satisfy the demands of their clients and provide them with fresh, inventive solutions. 

 Advantages of Agile

Many benefits are accrued by those who follow the Agile methodology:

• Better Quality Products: Testing is an integral aspect of the project implementation stage in Agile methodology, which implies the total grade of the finished product is higher. The client is kept informed throughout the development cycle and has the ability to request changes based on market conditions. 
• Increased Customer Satisfaction: Customers are always included in the judgment cycle in Agile, which leads to higher customer loyalty.  You provide greater benefits to the customer and guarantee that the finished product is actually suited to their expectations by keeping them in the fold and making adjustments based on their input.
• Improved control: Because of its openness, feedback inclusion, and quality aspects, Agile enables managers to have more influence over the process. All through the project’s execution phase, quality is assured, and all participants are kept informed with daily status reports using robust reporting instruments and processes.
• Greater adaptability: When Agile is properly applied in a development team, it allows for unprecedented flexibility. Teams operate in shorter bursts, with the product owner providing frequent feedback and interaction.
• Lower risks: Any project that follows the Agile technique should never fail, in theory. Agile operates in tiny sprints with the goal of delivering value continually. Even if a certain technique does not go as anticipated, there must be a small element that can be retrieved and utilized in the future. 

Disadvantages of Lean Methodology

While a valuable approach, Lean is not without its own sets of disadvantages:

• Inventory Issues: Inventory is deemed inefficient in a lean organization, thus only a small amount of stock is maintained on hand to reduce carrying costs. While this seems beneficial, it also places greater reliance on suppliers, who must hope that they will be able to handle the necessary adjustments in order to produce swiftly and efficiently. A company’s success could be jeopardized if the inventory system is disrupted.
• Costs of Implementation: Lean management is sometimes applied to an organization that has seldom utilized it before. All systems and manufacturing processes will very certainly have to come to a close in their present state. Companies that are not equipped for the additional costs of introducing new hardware will be hit hard by this event.
• Difficult Transition: Owing to the facility’s complete transformation, transitioning from the previous method is difficult. This will necessitate a significant amount of patience and overhead, as well as a full revamp of work methods. As a result, it is critical for leaders to be open about future changes in the organization. 

Disadvantages of Agile

Some of the disadvantages of Agile are:

• Inadequate resource planning: Since Agile is predicated on the premise that teams simply don’t know what their ultimate outcome (or perhaps even a few iterations of deliverables down the track) will be like from the start, it’s difficult to anticipate project costs, time, and resources from the outset.
• Scarcity of documentation: Documentation occurs across an Agile project, and is frequently “just in time” for generating the output, rather than from the start. As a result, it gets less detailed and frequently falls to the bottom of the priority list. 

Conclusion

Both Lean, as well as, Agile provide a set of guidelines that can be used in application development to ensure that the appropriate product is provided as soon and efficiently as feasible. While the basic principles of Lean and Agile have been compared in this piece, it’s crucial to recognize that they are not mutually incompatible. When it comes to project management, companies could be both, Lean as well as Agile.
