result from investigation a containing recommendation among others as follows:
doesn't take steps anything? is not found problem
do system maintenance? little problems
increase ability or user know-how
considering system modification according to total
laid problem that into system development plan soon done

why necessary tactics?
find all problems
detect problem appearance cause
determine correct solution
be done so that all system elements can get solution tender without disturb their activity

several tactics that can be done:
listen system executant opinion
don't give beginning solution
compare story several system executant persons towards case same
look at problem inkonsistensi logikal

analysis need
intensive interaction stage between system analyst with end where does system development team show the skill to get conception and user belief so that get good participation.
4 aims that want achieved:
explain system in its entirety
describe ideal information system
bring ideal information system to condition in this time with pays resource obstacle
give push towards user confidence into system development
method
question and answer
kuisioner
observation
analysis procedure
document observation

analysis need

resource obstacle
time
money
skill
technology
external factor
analysis need document
analysis directive: connection with user ends, process observation, troubleshoot in data collecting
user need: need actually, report need, training need and new system influence
system obstacle: explain time obstacle and cost, skill, technology and external factor
document shaped data collecting instrument, statistics consensus, data current according to logikal and physical, beginning data element in data dictionary.


generating systems alternatives

how does manner juxtapose system condition in this time with system condition ideal?
make alternative to break information system problem
best alternative applieds wisely
strategy choice
menytributed versus centralized processing
information decision change from centralized data processing to decentralized end user responsibility center
integrated versus menypersed database
system designer must considering data everything that enters in data base and come into file
surround strategy of system development
environment around important strategy in the case of pengambilalihan companies because information system from company other may be differ from to company in this time.

selecting the proper system

tactics compares: system is compared based on cost and profit relatively; there 3 system manners a said superiorer with another system if:
a has lower cost from b and profit both same
a has lower cost from b and a produce profit more than b
a and b has cost same but profit that produced a more many.
several methods komparasi system
break even point analyisis
payback period
menycounted payback period
internal rate of return

selecting the proper system
katagori cost
hardware
software
people
suppliers
teleccommunications
physical sites
cost details
compare information system cost passes system life, analyst memproyeksi what cost change for and there 3 information system cost models that is linear, eksponensial and step function

selecting the proper system

information system cost can happen once and can also happen chronically.
information system cost that once that is ontime cost and development cost that moment system development.
information system cost that continually mengantaranya reccuring cost with operational cost where does this cost happen moment information system operate every day.

mempresentasi system study

do presentation in a word
decrease technique explanation in detail
mempretasi clearly by means of help visual
if use model uses for example medium laptop so that informativeer
emphasize profit from information system proposal with a few alternative appropriate condition that undergone to company.

decision continues or not
if company to decide to develop system so information departement will do process furthermore that is system design process.
if on the contrary so system development life cycle (sdlc) be stopped.
frequently be found problem with study system and and usually top management will ask melakukannya reworking towards study system.
model will explain stages some part that repeated and sometimes information departement will make to repeat stage before explain study system.
alternatively, decision to repeat a stage sdlc previous or bot to speak of go – no –go decision.
