3.6 FlexibilityA clear result <strong>of</strong> respond<strong>in</strong>g to a dynamic environment is that organization change <strong>the</strong>irproducts and services and changes <strong>the</strong> way <strong>the</strong>y do bus<strong>in</strong>ess. This performanceobjective is known as „flexibility‟. Flexibility is <strong>the</strong> ability to adapt, <strong>in</strong> a reversible manner,to an exist<strong>in</strong>g situation, as opposed to evolution, which is irreversible (Bucki andPesqueux, 2000). Flexibility means be<strong>in</strong>g able to change <strong>the</strong> operation <strong>in</strong> some way.This may mean chang<strong>in</strong>g what <strong>the</strong> operation does how it is do<strong>in</strong>g it or when it is do<strong>in</strong>g it.Specifically, customers will need <strong>the</strong> operation to change so that it can provide fourtypes <strong>of</strong> requirement namely, product/service flexibility, mix flexibility, volume flexibilityand delivery flexibility.Flexibility measures how good <strong>the</strong> supplier is at shorten<strong>in</strong>g <strong>the</strong> agreed lead time whenasked, (Roy, 2009).

Afive-po<strong>in</strong>t Likert Scale was used <strong>in</strong> <strong>the</strong> questionnaire to assess <strong>the</strong> four performanceobjectives.Prior to data collection, a pre-test<strong>in</strong>g <strong>of</strong> <strong>the</strong> questionnaire was conducted to ensurecomprehensiveness, clarity and reliability <strong>of</strong> <strong>the</strong> research <strong>in</strong>strument. The questionnairewas pre-tested among 15 customers at random and only m<strong>in</strong>or modifications weremade to <strong>the</strong> word<strong>in</strong>gs <strong>of</strong> some survey questions.
