If R&D is needed, we typically develop a Statement of Work (SOW) and revise that until we both agree on it. From there we will generate Rough Order of Magnitude (ROM) pricing as a checking point to make sure we are aligned on budget. We will convert the ROM to a formal proposal. After acceptance of the proposal and terms we start work on the program.The time it takes to complete a job depends on the size and complexity of the project, the current backlog, and the delivery of any materials that may be required. However, most EWI initial phase projects take 2-3 months.
