Vendor-Support Systems. The use of Turnkey Systems is
widespread amongst users of CBAS (Ismail et al, 2003) [16];
Relhan (2013) [30]; Sam et al.,(2012) [33];. They are often
completely finished applications, tested ready for
implementation, usually either generalized or
industry-specific. They are also made available as compiled
program modules although with limited allowance for
customization. (Hall, 2011) [13].
