DreamSoft4u excels in providing high-quality solutions and services to the clients across the globe. Our continuous delivery of utmost quality software development services at cost-effective rates within the stipulated time is possible due to our standardized development process and methodologies.
There are many development models/methodologies like Waterfall, Agile, Scrum, Spiral etc. but a single system development method isn’t necessarily appropriate for all types of projects. Each of the above mentioned models is best suited to a specific type of project, based on clients’ requirement, project’s requirements, its aims and goals and technical and project considerations. We therefore properly research, evaluate and then adopt a suitable development methodology.
We have considered all the major methods of developing robust applications like Waterfall methodology, Agile methodology, Scrum development, Spiral method and Test Driven development. We follow a well-defined process for each development method taking into consideration the varied requirements of clients like new development, custom development, enhancements, upgrade, migration, re-engineering, integration etc.
As one of the leading IT solution providers, we have offered top-notch applications to our clients by simplifying the process of these development methods and simultaneously meeting their expectations in terms of functionality, cost, efficient project management and delivery schedule.
The models used by us are benchmarked and continuously improved on the basis of better practices and as per the latest technology. The standard models are tailored as per the clients’ requirements to make them project specific. By using these methodologies we have delivered excellence to achieve outstanding results, leading to clients’ satisfaction.
Agile development model is based on iterative and incremental approach where the application is developed in incremental cycles. This innovative approach is best-suited for a project which demands flexibility i.e. where the requirements aren’t fully known and change as per the time and market conditions, requiring recurrent alterations. This iterative process lays stress on simple code, repeated testing and requirements adjustments and fulfills the needs of clients asking for delivery of functional pieces on an on-going basis instead of a single large release. As the project can be divided into manageable units, the developers can focus on each of them individually, resulting in high-quality software, leading to customer satisfaction.
The clients get deliverables on regular basis in Agile which makes them launch the application in the market with essential features immediately, ensuring quick time-to-market. It is also a cost-effective method of development, eliminating the need of up-front investment due to project being divided into phases. The project can be managed and controlled easily due to the short development cycles, thus saving it from getting uncontrollable. Agile method requires continuous interaction with the clients to discuss project requirements and success at each stage. This gives flexibility to bring important changes and implement new features in the application. Limited planning and less documentation is required in Agile as clients’ feedback plays a key role and changing business needs are to be addressed. This method also ensures transparency and results into tailor-made software that is best-fit for the customer.
Waterfall is a traditional model where a fixed process is followed for developing an application. It is a linear sequential flow, flowing steadily downwards just as a waterfall, with phases from requirement gathering and analysis to support & maintenance. In this method the next phase of development starts only after the completion of the previous phase. There’s no going back in waterfall approach to the previous stage to bring changes if any, in clients’ requirements. It is not a flexible method, but it saves significant amount of time, involves proper planning and scheduling with stages and activities well defined, thus making it simple and easy to understand and use. This model assumes that everything is carried out as per the planning, thus involving proper documentation with the deliverables and milestones identified from the beginning.
Though it has a complete cycle of development but testing is carried out at every stage for detecting errors and ensuring quality. A review is done at the end of each stage to check whether the project is on the right path or not and can it be continued further or needs to be discarded.This method is best-suited for a small development project in which the requirements are known, certain and fixed before the development process starts. It can be used when product definition is stable, technology understood and resources have less experience.Importance is given to target dates, budgets and the deployment of the entire system at once. As less customer interaction is involved during the development process, the application is demonstrated to the clients once it is fully ready.
Scrum is an agile methodology for a development project. It injects simplicity and flexibility in the project through its emphasis on factual feedback, self-management of teams and development of properly tested product increments within short sprints or iterations. Scrum has three main roles: Product Owner, Team and Scrum Master. This method involves a living backlog of prioritized work to be completed. The team takes a small chunk from the top of the sprint backlog and works on implementing those pieces within a certain span of time (known as sprint). Every day the team meets to assess its progress (known as daily scrum) and discuss the upcoming work with the Scrum Master and the Product Owner. During the whole process the Scrum Master helps solve the issues faced by the team if any, to keep the project moving.
The sprint ends with the review and retrospection by the Product Owner or other stakeholders to identify opportunities for improvement in the next sprint. The feedback loop is important in Scrum development as it may result in bringing changes in the delivered functionality or it might just lead to adding items to the product backlog. The cycle continues until enough items in the product backlog are finished or the budget gets exhausted or the deadline arrives. Scrum encourages self-organizing teams, enabling communication across all team members, the Scrum Master and the Product Owner. It helps the team members to respond to the emerging challenges in an agile way. This method is best-suited for managing complex software development projects. It gives a boost to the productivity and reduces time, helping organizations adjust to the continuous changing requirements and meet the evolving business goals. Scrum increases the quality of the deliverables, helps to cope up with the changes, gives better estimates, provides a greater control over the project schedules and ensures that customers’ expectations are met.
Spiral is a sophisticated model which reduces the early risks in the development project, focusing on identifying and eliminating project risks at an initial stage. It combines the elements of both design and prototyping-in-stages. The main aim of this method is to assess the project risks and minimize them by breaking the projects into smaller units, thus providing the ease-of-change and simultaneously assessing the prospects of the project continuation throughout the life cycle. A spiral project starts on a small scale, explores the risks, devises a plan to handle risk efficiently and then takes a decision whether to go to the next step or not. This method has an effect on the delivery time but is quite useful for projects which are large, mission-critical and complex or are risky. Spiral model is best suited for high-risk projects with varied needs, where costs and risk evaluation is mandatory and where there are chances of significant changes.
Spiral methodology has four stages: planning, analyzing the risk, engineering and evaluation. A project would pass through these stages in iterations which are known as spirals. Planning involves requirement gathering and preparing system requirement specifications. Risk analysis stage has the process of identifying risks, coming up with alternate solutions and implementing them in case of any risk. A prototype is produced after the risk analysis is completed. Engineering phase involves development and testing. The final evaluation phase allows the customers to assess the output before the project takes on the next spiral. This method provides flexibility to add functionalities at a later date. It ensures clients’ satisfaction due to their involvement in revaluating the prototypes repeatedly. The model also promises better productivity due to reusable capabilities, keeping a control over cost, time and resources’ requirement.
Test Driven Development is a type of agile development methodology, consisting of small development iterations. In this method, short development cycles are repeated, which involves the developer to write an automated test case that defines a new functionality or an improvement. He then develops the minimum amount of code to pass the test and at the end refactors the new code to acceptable standards. TDD thus focuses on tests and reverses the way of development. This method involves Red/Green/Refactor cycle, which indicates repeating number of the following steps: Red: writing unitary test that fails before the functional code is written; Green: writing functional code until the approval of the unitary test and Refactor: removing redundancies and restructuring the code in case of any improvement, for the success of unitary tests.
Applications of high-quality within less time can be built through test driven development method. For proper implementation of this methodology, the developers and the testers need to properly anticipate the use of the functionalities and features of the application in the real world. TDD ensures that the units in the application are thoroughly tested for optimum functionality at the very beginning of the design cycle to save time and money spent in debugging at the later stage. This method helps in improving designing qualities in the code which leads to robust quality applications, resulting in customer satisfaction. TDD also helps in improving the design; documents the public interfaces and provides protection against future mistakes that might occur during the development.
