Scope of Work

Rally had been requested to vet 18 work orders to determine the overall scope as well as to provide a budgetary estimate for completion. Rally had reviewed the WOs at a high level with the client engineering. This information, coupled with our experience in completing this exact type of work for the client previously, had been used to determine the budgetary estimate. Rally provided a budgetary number of hours to complete this effort.
