1ata Analysis

i(en the (ario%s problems+ a complete analysis was &one in or&er to &raw possible sol%tions*

The main problem face& by the team at hen!"s #holesale an& their c%rrent software is that the c%rrent

software lac) certain f%nctions which will be state& later+ as well as bein! too &iffic%lt to !et

acc%stome& to or not bein! %ser frien&ly* To i&entify the e6tent to which each problem affecte& the

b%siness two fact fin&in! tools were &isb%rse&* 0. A '%estionnaire to be &istrib%te& amon! former if

any. an& c%rrent cashiers+ after they ha(e trie& a &emo of the pro!ram+ which is to be fille& o%t an&

s%bmitte& from which it will be accesse&+ an& 4. A list of '%estions were or!aniBe& to be as)e& to the

boss@mana!er of the b%siness to see any f%rther specifications which he will &esire*

#hat the c%rrent pro!ram %se& by the cashiers is lac)in! is that it cannot &o an in(entory search

to see if an item is in stoc) while &oin! a transaction* ,or e6ample+ say a c%stomer or&ers three colas+

when there are only two in stoc)+ the cashier can still enter the three colas into the transaction witho%t

recei(in! any warnin! that there are only two left* They wo%l& then ha(e to !o o(er the list an& correct

this+ wastin! (al%able time* Cy sol%tion is to r%n the in(entory pro!ram alon!si&e the pos pro!ram in

the same pro!ram so that f%nctions can be written in the pos to chec) the in(entory before a&&in! the

item to the transaction list* If the '%antity of the item re'%este& is not a(ailable+ then a messa!e will

appear sayin! somethin! li)e DOnly 6" amo%nt of that item are c%rrently in stoc)+ wo%l& yo% li)e to re-

enter the '%antity2F which wo%l& sa(e the cashier the hassle of !oin! o(er the list to remo(e the item*

The acco%ntin! aspect of the b%siness was also analyBe& an& it was &eci&e& that alon! with the

in(entory+ there sho%l& be a sprea&sheet showin! the flow of money+ how m%ch is spent an& what it is

spent on* A '%estion in the '%estionnaire in the fact fin&in! tools was aime& at &eterminin! if the

acco%nts of the b%siness was han&le& by the boss or if they hire& an acco%ntant to han&le the acco%nts+

it was tho%!ht ahea& that if it were the case where they ha& to hire an acco%ntant that they wo%l& ha(e

no nee& to beca%se the sprea&sheet wo%l& a%tomatically han&le all acco%nts+ ma)in! this a bon%s for

the b%siness beca%se it wo%l& sa(e them the cost of hirin! one*

Gser frien&liness was a feat%re of the pro!ram that was also analyBe&* ertain %ser interfaces

may be too m%ch to absorb for the %ser in terms of layo%t* Instea& of %sin! a !raphical interface this

pro!ram will %se a men% &ri(en one followe& by tables to try an& ma)e the %ser e6perience as simple

an& comfortable as possible*
