In general, depending on our specific needs, we can use various methods known in practice for successful project management, and why not hybrid interactions where possible.
To date, the so-called Waterfall and Agile are considered to be the most widespread project management methodologies. Reference: “Agile vs Waterfall Project management and software development with Scrum“
Waterfall is considered a sustainable methodology for project management for years, consisting of static phases (requirements analysis, design, testing, implementation, and maintenance), which are performed in a certain order.
It is consistent and is used in many industries, most often in software development. Reference: “Agile vs Waterfall project management“, https://pgov.org/agile-vs-waterfall-project-management/
Waterfall allows increased control during each phase but can be very inflexible if the scope of the project changes once it has started. It offers a more formal planning stage, which can increase the chances of covering all the requirements of the project from the beginning, reducing the loss of some key information and requirements in the initial stages. Reference: “Agile vs Waterfall Project Management”, https://pgov.org/agile-vs-waterfall-project-management/
The characteristic here is that one phase of the project cannot start until the previous one is completed, typically the model has between 2 and 7 phases.
This model is suitable for projects that have clear requirements from the beginning, no structural changes are foreseen during the course, there is a clear start and end date of implementation.
The Agile model consists of short performance cycles called “sprints”. It was originally developed for projects that require considerable flexibility and speed. Agile may be best suited for projects that require less control and real-time communication in the attitudes of a self-motivated team. Reference: “Agile vs Waterfall Methodology – What are the differences“, https://www.islandjournal.net/agile-vs-waterfall-methodology-differences/
As a project management methodology, agile is very interactive, allowing for quick adjustments during project implementation.
Agile teams anticipate and proactively scan for changing requirements. The “minimum viable product” (MVP) is tested by the customer who provides feedback. Reference: https://www.businesspad.org/agile-vs-waterfall-difference-between-methodologies/
This leads to changed requirements. The development is necessarily iterative, instead of a linear sequence. The teams are multifunctional, with regular interaction with customers.
Common models are Kanban, Lean Six Sigma.
Kanban focuses on continuous collaboration and creates an environment of continuous learning and improvement. This method uses visual boards and maps to help teams see tasks that have been completed, and those that have not been completed.
All activities are based on the ability to visualize the tasks for the day, carefully balance the work performed, and manage the backlog. Reference: Agile vs Waterfall management methodology, https://www.kosovatimes.net/agile-vs-waterfall-management-methodology/
Lean Six Sigma
Lean Six Sigma, created by Toyota, Lean was designed to focus on reducing resource loss while maximizing results. Although Lean got its start in the manufacturing industry, today it is used in various industries, as its focus is not specific to the sector. Reference: “A Management Educational Library“, https://customessaysonline.net/
The Lean and Six Sigma hybrid focus on the consumer to improve business efficiency and effectiveness. Lean Six Sigma strives to improve processes, eliminate unnecessary redundancies and reduce defects.
The Waterfall method
With the Waterfall method, we have precisely described the stages along which our project is moving. For each stage, there is a clearly defined team with a specific task. Reference: Waterfall and Incremental model in project management, https://wikipedia-lab.org/waterfall-and-incremental-model-in-project-management/
After completing one stage, we move on to the next, without returning to ready at some point.
With this method, it must be clear in advance what the result the client wants, there is no possibility to change the project during the implementation. Reference: Agile, Scrum and Waterfall project management, https://ossalumni.org/agile-scrum-and-waterfall-project-management/
Very suitable methodology for small projects in which the goal is clear and no change in the work process is expected.
There is faster execution due to the clear stages.
It is not suitable for large projects in which the client does not have a clear and accurate idea of the final product. Reference: Agile, Scrum and Waterfall project management, https://ossalumni.org/agile-scrum-and-waterfall-project-management/
The tests are performed with a ready-made project, which can lead to unwanted problems detected at a late stage and difficult to eliminate.
In this methodology, more people are needed to complete the project, because everyone is responsible for a specific stage of the project.
Reference: Agile Project Management includes different subjects and many Agile and Scrum practices as well, but we will discuss here several major topics… https://agileprogramming.org/agile-project-management/
The Agile method
The Agile method, on the other hand, is flexible, focused entirely on the customer’s wishes.
In this model, the client takes a direct relationship to each stage of project implementation. Reference: Comparison of Agile, Scrum and Waterfall project management, https://eduwiki.me/comparison-of-agile-scrum-and-waterall-project-management/
Here we can work on several stages of the project at the same time, and at the request of the client, we can go back to the stages and change already completed steps.
A suitable method for larger projects in which the client can change the assignment during the work. Reference: “MuzoNet, Management and Business“, https://www.muzonet.com/
The teams responsible for the implementation of the different stages may overlap. They self-organize and self-regulate.
This method is inappropriate when the client does not have a clear idea of the final product and this can lead to the failure of the whole project. Reference: Waterfall or Agile? What methodology to choose for your project?, https://pm.mba/posts/waterfall-vs-agile/
Our organization could work with both models, depending on what project we have in front of us. For us, the best model is Waterfall because we will have clearly defined deadlines and responsibilities at each stage of the project.
If we have a larger project related to construction, for example, the Agile model would be better, because the customer’s requirements are constantly changing.
