Managed Services

  • Sigma,over the years has assimilated Technical Knowhow and expertise which has enabled it to create Intellectual Capital which is being constantly replenished by its Training Department.Today we are an active and vibrant partner for OEMs and outsource trained personnel in large quantities at all levels. Our resources go through our in-house training on our task based services and regular training sessions and that makes us different from a simple manpower supplying agency. In this model, the manpower remains on the payroll of Sigma and the resources are assigned to the customer. This model is ideal for customers who either need a solution for peaks in their requirements or have a long term requirement but don't want the additional burden of head-counts on their books.
