Question

1. NewTechSystems has contracted with a well-known regional consulting company (RCC).  In the original contract, the agreement was for time-and-arrangements, but lately it seems like there are excessive time amounts and excessive arrangements.  Sometimes what seems minor to NewTechSystems with an estimated time of under 2 hours takes RCC 20 hours.  What discussions need to take place?
2. What types of influences are there on determining the type of installation to pursue with relation to resources and the acquisition of a new system?
3. At the end of the design phase, there is a document named the system specification that describes the different design documents and their uses. What is the consolidated purpose of this deliverable and why is it important?
