Magora: We’re Here to Drive You to Success

Founded with the mission of delivering top-class bespoke software development, Magora has reached the top three among UK developers based on the independent reviews. We back this up with commitment to quality, superb project management and total dedication to customer service.

We strive to meet the client’s needs and choose strategies individually with due attention to each unique case. Though we’re experienced in the Agile approach, our developers work as Waterfall software development professionals and know everything about fixed terms and budgets.

Waterfall Software Development - What it is?

Waterfall is a software development model that is useful when all the details of the project are clear and agreed. Everything is set out in a professionally developed SRS (software requirement specification) and the task is simply to implement the preset software architecture in the programming code. This approach is perfect if you have a fixed list of requirements and a clear view of the final product.

Taking into account that in the changing business environment it’s not always possible to preset all the necessary features and functions, in some cases we recommend switching to agile development to achieve results with more flexible demands.

According to the Waterfall model, developers move from one stage to another in strict order. First, the requirement specification stage is completed and a list of software requirements fixed.

Once the requirements are fully defined, the team will proceed to the design phase. We need to create a document that details how the software looks and work out a detailed plan to implement these requirements for the programmer. After the design is completely executed, the developer implements the project code.

In the next stage of the process, the experts integrate the individual components developed by the different teams of programmers. Once implementation and integration are complete, the product will be tested and debugged. At this stage, all the errors that appeared in the preliminary stages of development are eliminated. Afterwards, the software product is implemented and the developer provides the necessary support, introduces new functions and eliminates the errors.

Waterfall technology is the brainchild of W. W. Royce, Director of the Lockheed Software Technology Center, Pioneer of Software Development in Austin, Texas, USA.

Walker's original work "Managing large-scale software system development" outlines the creation of six-step products established as a standard for the US Department of Defense. Work in cooperation with software developers began in 1985.

  • System and software requirements: solved in PRD (product requirements document).
  • Analysis: included in models, schemes and commercial rules.
  • Design: the internal architecture of the software and how to implement the requirements is defined. This is true not only for the interface and appearance of the software, but also for the internal structural logic.
  • Coding: the program code is written directly and integrated with the software.
  • Test: the error tester verifies the final product and records information in the program code or function defects in the tracker. In case of error or availability of time / background, the error is fixed.
  • Operation: the product adapts to various operating systems, is periodically updated, corrects errors detected by users and adds features. At this stage, we provide technical support to customers.

The limitations of such severe restrictions allow for the building of development processes that are as transparent and convenient as possible for clients.

This model means that each stage of the project will be implemented strictly and consistently once. The transition from one phase to another is only possible after the previous stage has been successfully completed. Each stage means perfect precision of detailed planning and results.

The reverse side of the waterfall software creation process is that developers must maintain the product documentation and constantly update it. Changes must be agreed upon with the client. Insufficiency in this area will increase the budget and the project schedule, which in turn will be very difficult to evaluate.

Waterfall is, however, very suitable for several transparent projects. Due to the high level of formalisation, these are much easier to administer. In general, it is believed that the Waterfall software development model reduces risk and clarifies the process by which 12 people work on any given project.

The Waterfall model is a perfect suite for developing large and complex projects and software systems with strictly defined functions when handling large orders, science and technology.

Among the drawbacks of the waterfall method we can note.

As this process has no flexibility, if the project requires as much time and money as possible, the testing phase will be affected. According to our consulting group survey, the cost of repairing faults after product launch is 20 times the average of full-scale multi-step testing during the development process.

  • Resistance to change: the strict framework of the development stage and the condition of providing only finished products cannot be changed at any point during the project.
  • Low flexibility: during the first phase, temporary and financial expense predictions may fluctuate, but altering the project in function or concept before the finished product release for the purpose of cost optimisation is impossible.
  • Higher risk: when following agile principles, a software product is tested on every iteration and each component of the project is checked separately and involves interaction with the whole environment. When following Waterfall, only the finished software will be tested.

The drawbacks of the Waterfall development model were partially corrected in the renewal of the method. Sashimi, a process including subprojects, is a waterfall model with built-in risk reduction.

The Sashimi model, or waterfall with hierarchical stages, is the most famous of them all. The stage and the original technique advance one after another, but as time goes by they overlap.

  • Waterfall with subprojects is a model that works with three big blocks - conceptualisation, design of requirements and structure of the product architecture. Next, we execute detailed design, coding and test stages (subprojects) for each of them. Finally, all the components are integrated into the test phase of the system.
  • The Waterfall software development model with risk reduction is a classic waterfall arrangement with the addition of a risk reduction spiral that divides the project into mini-projects and responds to one or more significant risks.

The main advantages of the Waterfall methodology are the following.

Simple, easy to understand process structure: reduce the entry threshold of the development team.

  • Convenient reports: easily track resources, risks, time and finances with strict stages of the development process and detailed software documentation.
  • Task stability: all the challenges the product may face are clear to the team from day one of the development and remain unchanged throughout the process.
  • Evaluate cost and time: the launch time and final cost of the final product can be calculated before the development of the software begins.

Does the Waterfall Approach Fit your Needs?

This method is suitable for the following cases:

  • A medium or large project, where dozens of programmers and several different teams must participate.
  • A project where limits and requirements are transparent and that accurately captures what the final product should do at the beginning of the software development life cycle.

Finally, the Waterfall approach is the precise method needed if the main potential terminator of the project is implementation, not finances.

We’re the Best Team to Bring Your Ideas to Life

Magora is an advanced IT group with excellent technical suitability and teamwork skills. We experiment with proven project management techniques.
