Big Bang v/s Phased Transition Approach Determining the right zero-risk model

Transition Methodology (approach) is the process of taking over the services from an in-house IT or an incumbent service provider. It takes center stage during the entire course — from the assessment phase to the steady state phase. In addition, transition methodology has a direct bearing on the timelines, resources, and risk management ability, and on ensuring zero disruption to the business.

Managed services engagements are performed using one of the two models in transition methodology— Big Bang or the Phased Approach (also referred to as Wave methodology or step-by-step model). HCL understands that no two requirements are unique. Therefore, we ensure that the solutions are tailored to meet the unique requirements of our customers. At HCL, our recommendations/transition strategies are based on the engagement (Onsite-O shore / Onsite- Near shore-O shore) proposed model, and the current state of outsourcing maturity at the client’s side. It also depends on the geographic spread of different business units in the customer environment. The transition strategy is decided after conducting an in-depth assessment of the customer’s organization, its operational pain points, and outsourcing requirements.
