Assigning software development activities to outsource partner is a strategic business decision most companies are adopting now. In-house software development is not a viable and cost effective method considering many draw back associated with this. Companies are outsourcing software development to the experts mainly due the following challenges:
- Non-availability of skilled manpower
- Cost benefit
- Requirement of faster delivery
- Own development team is overloaded
There are a number of software delivery models available for a company. All have its merits and demerits, but identifying the best one which suit own business requirement is a strategic decision company need to take. Following are the software delivery model options available in the industry.
In this model, the development centers are located outside the country and team lead stationed at client country may be co-ordinating with the customer and development centre. In some scenario, both team lead as well as development team also stationed outside country and customer will be directly interacting with offshore team.
In onshore software delivery model, development team is located within the client country. This will facilitate effective communication and co-ordination with customer and development team.
Onsite software delivery model facilitate optimal communication and co-ordination as the development team will be stationed at client facilities. Although it will have some additional cost involved but is an effective development strategy.
In this delivery model, software development team members are distributed. Reduced cost and maximised effectiveness is the benefit of this model.
While discussing software delivery models, we need to see different software development models and strategies. Some of the common software development models are Waterfall Model, Spiral Model and Evolutionary Model. The common methodology used generally is Waterfall Model. This has five basic steps or stage of development.
Requirement Stage: Here the requirement of business, information, behaviour, performance and expectation are generated and shared.
Design Stage: Here data structure, software architecture, interface and other design activities are implemented.
