Question

(I wrote the whole thing so you can have an idea abou the question as a whole. i just need answer for question number 4);Capstone case:New century wellness group;New Century We l lness Group offers a ho l istic approach to healthcare wi t h an emphasis on preventive med i cine as well as trad i tional medical care. In your role as an IT consultant, you willhe l p New Century deve l op a new information system.;Ba c k grou nd;Based on your earlier recommendat i ons, New Century decided to continue the systems development process for a new information system. Now, at the end of the systems analysis phase, you are ready to prepare a system requirements document and give a presentat i on to the New Century assoc i ates. Many of the proposed system's advantages were described during the fact - find i ng pro cess. Those include smoother operation, better eff i c i ency, and more user - fr i endly procedures for pat i ents and New Century staff.;You a l so must examine tangible costs and benefits t o determine the econom i c feasibility of;severa l alternat i ves. If New Century decides to go ahead with t he deve l opment process, the ma i n opt i ons are to deve l op the system in - house or purchase a vertical package and conf i gure it to meet New Century's needs. You have stud i ed t hose choices and put t ogether some prelim i nary f i gures.;You know that New Century's current work l oad requires s i x hours of office staff overtime per week at a base rate of S15 per hour.

Neither the overtime nor t he addit i onal j ob will be needed if New Century i mplements the new system. The current manua l system also causes an average of three errors per day, and each error takes about 20 minutes to correct. The new system should elim i nate those errors.;You es ti ma t e t ha t by working full - t i me yo u could comp l e t e th e p r oject i n a b ou t 12 weeks.;Your consul ti ng r a t e, which New Cent u ry agreed t o, is $35 per hour.
