Importance of Offshore Software Development

It is important to manage your technology that you follow. Whatever may be the technological strategies that you employ it is necessary to supervise them. Companies make use of offshore industry executives’ extensive experience to give a competitive edge. It is not easy to manage technological advancements and one needs an IT professional to carry out this.

Rapid growth in the field of computers has eased out the paper work in companies. People have become techie and carry out all their tasks online. It is easier to maintain customer database through client database management systems. Software developers have developed tools to make your office paper work easier. Client relationship management, customer database tools have eased out the whole process of maintaining database and creating simple reports. This has helped to cut down on time and control information too.

It is indispensable to comprehend the complexities of software development. Being away from the client’s office the offshore company must know how to control the tolls online at various development stage. They should also be able to co-ordinate with the clients well and maintain security of the client’s data. As all the activities are carried out online, it is essential to safeguard it from hackers.

Make your clients aware of the process and procedures involved in creating software and maintaining embedded systems. The success of any outsourced company would depend on how well they are able to clearly understand the client’s technical requirements and make them understand about your processes too. Clear communication is the need of the hour.

Software Development Projects And What Are The Best Methods

What are the best methods for software development projects

The crucial component is when choosing the correct software development life cycle process that is required to create the project, as all other processes are comprised from this process. The software development projects including the spiral method may often be used instead of the waterfall method.

This way any problem may be corrected early and ensuring the testing process has more chance of success. The artifact from the development process can then be analyzed.

The testing process is an imperative part of software development that needs to be planned prior to coding. The testing process is created during the application designing and coding phase.

The project management remains essential to the success of the project. The project manager is constantly aware of these expectations. Rapid Development RAD is one system.

There has also been a notable change to the software process recently, this has been the emergence of the terminology: agile. The agile software methods and the introduction of agility to the development team, determines a change to the well established processes.

Communicating is crucial to success. Including the developing software development plan combining strategy. The architecture and any design or coding requirements. It is of great importance for the development team to know exactly what needs to be created.

As the majority of the software development is a hectic process, termed code and fix, as the software sometimes is created without a correct plan or only short term emphasis. This can work with a small project but as the system grows it is very difficult to add new elements to the system. In addition to this bugs can become a big problem and can be difficult to fix.

The entire software development plan and processing of any system will require the main components of communication, management, planning, testing and implementation. These steps can create ease.

Once a system is developed, it would be beneficial to provide troubleshooting and support to ensure the end user can actually use the software and also any bugs within the system may actually be made known through this process and ensuring to correct architecture for the development.

It is also important to ensure the design is also acceptable as the application must be easy to use, easy to understand and simplicity will contribute greatly to the success of this project and all future projects as there is structure.

Software Development Life Cycle and Testing

These five phases constitute the life cycle of a software project called the software development life cycle (SDLC).

The Five Phases of the SDLC:
1. CONCEPTION
2. INITIATION
3. ANALYSIS
4. DESIGN
5. CONSTRUCTION

Phase 1 – CONCEPTION: This phase starts as soon as someone, either a user or a member of the data processing department, recognizes a problem or opportunity that suggests a data processing solution.
The objective of this phase is to answer the following questions:

– What is the perceived problem (or opportunity)?
– What are the goals to be achieved by the solution?
– What benefits will result from achieving the solution?
– What will be the scope of the project?

These details may be recorded in an informal note or in a formal document. This document is called Project Request Form.

Phase2 – INITIATION: In this phase the analyst, working with the user, does a preliminary study of the user’s need. The information developed during this phase permits the organization to decide if it is worth spending money on the project.

The key information to be recorded consists of the following:

– Proposed system solution
– Alternative solutions considered
– Economic justification (Cost Benefit Analysis)
– Schedule of time and cost estimates for the completion of the project

This document is referred to as System Proposal.

Phase 3 – ANALYSIS: During this phase, the analyst and user come to a detailed agreement on the functions that the proposed system has to perform. A detailed document is prepared containing:

– Outputs to be produced
– Inputs that must be received
– Data to be retained
– Procedure to get the outputs from the given inputs
– Audit and control requirements: This specifies the features that are required to ensure that the user can monitor the system to check that it is working properly.

– System Acceptance Criteria: This lists the tests that the user would actually perform to check conformity with the previously agreed performance requirement and other specifications, before accepting the system.

This document is called Function Specifications. In addition to creating Function Specifications, the Cost Benefit Analysis prepared during the Initiation phase should be reviewed for accuracy. Similarly, the cost and time estimate should also be reviewed/revised.

Phase 4 – DESIGN: At this point, the emphasis changes from defining the user’s requirement to defining how the system will work. The documentation developed is technical. The design documentation should specify:

– Exactly how each input, output, operation, file and audit control requirement will be handled
– Acceptance test plan/schedule
– Facilities, equipment and personal required
– Manual procedure required to operate the system

This document is referred to as Design Specification. At this point again, the Cost Benefit Analysis and cost/time estimates are reviewed /revised.

Phase 5 – CONSTRUCTION: The last phase in the system development procedure includes three activities:

– Completing and testing computer programs and operating instructions for using the package (Run Manual, User Manual).
– Performing all tasks to carry out the conversion from the system currently in use to the new system.
– Conducting the final testing of the system to determine if it performs according to the acceptance criteria established during the Analysis phase.

Another essential activity for any system is the system evaluation. During system evaluation the performance of the system in a real life environment is assessed.

This is not considered a phase as:

– It may be several months before it is possible to take the first measurement of system effectiveness.
By this time the project development team might have been disbanded or moved to other projects.
– It is an ongoing activity. In fact, it should be regarded as a project in itself.
– The results of the system evaluation might indicate that the system has to be modified /re-developed.

Testing:
Software Testing is the course of completing a program or system with the intention of finding errors. Or, it involves any activity aimed at appraising an attribute or capability of a program or system and determining that it meets its required results.

The testing process:
1. Create test plans.
The test plan documentation consists of two documents:
• Detailed test plan (DTP) document
• Detailed test case (DTC) document
2. Review the design.
The design review also helps in identifying the scenarios that must be tested for one or more of the following:
• Possible security attacks
• Performance optimizations
• Profiling to ensure that there are no memory leaks
3. Perform black box testing.
Black box testing includes the following:
• Testing all of the external interfaces for all possible usage scenario
• Ensuring that the interfaces meet the functional specifications and address all of the requirements testing for various types of input.
• Testing for various types of input.
• Performance testing
• Load testing.
• Stress testing
• Security testing
