Application Development and Design
Application Development has many attributes that are associated with good software. Some of these can be mutually contradictory (e.g. very fast versus full error checking). Different customers and participants may have different priorities. Hence, our main goal is to create software that will meet our Client’s needs within restrictions of time, resources and budget.

Our software design objective
- Clear definition of purpose.
- Simplicity of use.
- Ruggedness (difficult to misuse, kind to errors).
- Early availability (delivered on time when needed).
- Extensibility in the light of experience.
- Efficiency (fast enough for the purpose to which it is put).
- Minimum cost to develop.
- Conformity to any relevant standards.
- Clear, accurate, and precise user documents.
When we design software, we follow “Weinberg” principles, making sure that our answer is YES to all of the following questions:
- Does a program meet its specification? is there “correct output for each possible input”?
- Can this program be produced on schedule and within budget?
- Is the program adaptable to cope with changing requirements?
- And is the program efficient enough for the environment in which it is used?

So, what is An Application development methodology?
It is a framework that is used to structure, plan, and control the life cycle of a software product. Depending on our Customer’s needs we use various methodologies. This include waterfall, prototyping, agile software development, rapid application development. We choose the most appropriate methodology for every particular project and development environment.

We follow waterfall methodology on projects where requirements are clear, unambiguous, and we have tight time-frame and tight budget. Waterfall approach presumes tight control of the project, which is maintained via extensive written documentation, formal reviews, and approval/sign-off by the key stakeholders occurring at the end of most phases before beginning the next phase.
We have embedded prototype methodology into the design phase. This provides our client with a clear picture and a basic understanding of the fundamental business problem as early as possible, which is necessary to avoid solving the wrong problems.
Waterfall software development is an easy but powerful method, which relies on disciplined approach to the project time, costs and business requirements.
Rapid Application Development
We use rapid application development for fast development and delivery of a high quality system at a relatively low investment cost while fulfilling the business need. This approach attempts to reduce inherent project risk by breaking a project into smaller segments and providing more ease-of-change during the development process.
This method of project control involves prioritizing development and defining delivery deadlines or “timeboxes”. If the project starts to slip, emphasis is on reducing requirements to fit the timebox, not in increasing the deadline.
Rapid application development approach suggests possibility and even necessity of evolutionary development of requirements throughout project lifecycle that allows us to build up flexible and adaptive process.
This approach incorporates iteration and the continuous feedback that it provides to successively refine and deliver a software system. It promotes adaptive planning, evolutionary development, early delivery, continuous improvement, and encourages rapid and flexible response to change.
Most agile methods break tasks into small increments with minimal planning and do not directly involve long-term planning. All requirements are organized into a set, sometimes referred to as a product backlog. At the beginning of iteration, the team determines items from the backlog to be delivered within the next iteration. Iterations are short time frames that typically last from one to four weeks. Each iteration involves a cross-functional team working in all functions: planning, requirements analysis, design, coding, unit testing, and acceptance testing. At the end of the iteration a working product is demonstrated to stakeholders. This minimizes overall risk and allows the project to adapt to changes quickly. Agile approach welcomes changing requirements, even late in development. Working software is delivered frequently (weeks rather than months).
