Procedure Analysis
Harmonizing to “Chicago Lake, ” ( 2014 ) , the entire grosss from gross revenues of spirits through the shops range from $ 10 million to $ 25 million and the employees in the shops are 250-500 employees, the East Lake shop has 43 employees. It is the largest spirits retail merchant of Minnesota, Minneapolis country by volume. The demand to provide big measures of spirits at low monetary values and with clean stock list studies, fast minutess, and unafraid information resulted to Chicago Lake Liquors make up one’s minding to put in a Point–Of-Sale ( POS ) by Catapult. The critique paper evaluates an information system about put ining of Point-Of-Sale ( POS ) by Catapult at Chicago Lake Liquors shops, which facilitates stock list direction, gross revenues tracking, payments processing, better client services and costs control. The best patterns by Chicago Lake spiritss apply the POS by Catapult, a follow the incremental SDLC theoretical account and full information backup.
A POS system allows the processing of payments through usage of equipment that is dependable and high acting.

Following best pattern is the usage of incremental SDLC theoretical account by Chicago Lake Liquors DBA. Harmonizing to Baltzan ( 2013 ) , the System development life rhythm ( SDLC ) is a system specifying projects performed at each phase in the development procedure. SDLC comprises of a comprehensive agreement picturing how to develop, keep, and replace the peculiar package. SDLC purpose was high quality system duplicate demands of client refering efficiency, effectivity, clip and cost ( Saini & A ; Kaur, 2014 ) . The incremental theoretical account has low cost characteristics, really long continuance, fixed necessities ; plus low care cost and allows intermediate engagement of user. The existent design of SDLC incremental theoretical account developed included the description and the physical system features preparation ( Baltzan, 2013 ) .
