This model, with the addition of external supply chain elements, is a m TamerQaqishSubmission2011correctionC_PJTFinal2011septanagement framework, which can be termed an agile manufacturing system.The development of this framework has raised the following data certainty questTamerQaqishSubmission2011correctionC_PJTFinal2011sept

In this approach, the principle of entropy was adopted to measure data uncertainty. The structured methodology was made possible by a new categorisation into Innovative. Standard and Semi-Standard cladding projects.The research TamerQaqishSubmission2011correctionC_PJTFinal2011sept applied this structured methodology, combining qualitative and quantitative methods for validating assumptions, to a cladding industry SME case-studyTamerQaqishSubmission2011correctionC_PJTFinal2011sept

The risk percentage formulae used were based on assumptions extracted from qualitative and quantitative methods applied to the SME, its partner companies and industry specialists. Assumptions about the gross margins for TamerQaqishSubmission2011correctionC_PJTFinal2011septUK metal cladding projects formed part of the risk percentage formulae.The results of this case-study found that gross margins varied from 5% in standTamerQaqishSubmission2011correctionC_PJTFinal2011sept
