Product development services are quite different from traditional services in several ways. In traditional services model, the work is defined, estimated, and schedule is drawn up based on resource allocation. Any changes to the scope leads to revisiting the schedule, extending budgets and/or timelines and of course more cost.
Product development services are different. They are time bound and a release date in pre-planned and announced by the product management team to the customer, partners and the prospects. Tentative feature list is drawn up and an iterative/agile development plan is made. Every Sprint is timebound (typically 2-3 weeks) and has a goal to meet. The scope of that sprint is agreed upon and at times the detailed design is discussed and agreed uopn across sprints or within a single sprint.
We work with our clients to understand their specific needs and fully align our efforts towards meeting their goals.
