EARLY WATCH, ANALYSIS’S REQUIREMENT

SYSTEM CONCEPT INVESTIGATES

1. Difference distinctive (gap) among system aim and condition of system actually

2. Reporting detects problem not quite a reality
* To the effect over ideal
* Lack for resource and or attitude
* System measurement less accurate
* To the effect system already is behind in
* The difference among idel's system and temporary system

3. Problem solving:
* System formulation that be walks → rinci's ala investigation
* Getting ideal system consensus
* Develop severally alternative
* Choosing the best one alternative

4. To the effect investigation → pointing out problem that actually happens


CONSTRAINT IN SYSTEM INVESTIGATES

1. In do investigation some constraint which often emerges is:
* Time
* Cost
* Scholarship
* Politics
* Interference

RECOMMENDATION

1. Result of investigation is one recommendation which contain for example as follows:
* Don't take action whatever → problem undiscovered
* Doing system preserve → little problem
* Increasing ability or user skill
* Regarding system modification totally
* Placing happening problem into systems developmental plan which shortly be done

TACTICS INVESTIGATES

1. Why needs tactics?
* Find all problem
* Knowing its appearance cause problem
* Determining solution in point

2. Done so all system element can accept solution offer without trouble their activity

3. Severally tactics which can be done:
* Listening system agent opinion
* Don't give startup resolving
* Comparing story some bodies system agent to same case
* Inkonsistensi logikal's problem looking at

4. Tactics investigates to exist two tricks which is :

Directly :
* Kuesioner
* Question-answer
* Watch

Indirect :
* Procedural flow
* Studying document
* Sample
* Tabular

CURRENT SYSTEM DESCRIPTION

1. Entry

2. Output

4. File

5. Data element

6. Transactions volume and action document

7. Data flow chart

ANALISIS'S REQUIREMENT

Intensive interaction phase among system analyst with end user where systems developmental team point out its membership to get comment and user trust so gets good participation.

4 AIM THAT WANT TO BE REACHED :
* Wording comprehensive system
* Figuring ideal information system
* Taking in ideal information system to condition of currently by notices resource constraint
* Giving push to wearing confidence into developmental system

Method
* Question-answer
* Kuisioner
* Observation
* Analisis's procedure
* Document watch

RESOURCE CONSTRAINT
* Time
* Money
* Membership
* Technology
* External factor

Document is analisis the need
* Analisis's instruction: Relationship with end user, watch processes, about problem in data collecting
* Wearing requirement: Real requirement, Write-up requirement, training requirement and new system influence
* System constraint: Wording time and cost constraint, membership, technology and external factor
* Document as instrumental as data collecting, statistical consensus, ala data flow logikal and physical, early data element in lexical data.


GENERATING SYSTEMS ALTERNATIVES

How to near current system condition with condition of system which ideal?

Making alternative to solve information system problem

That best alternative is applied one expedient

Strategy option

Distributed versus centralized processing
Changing information decision from centralized processing's data goes to decentralized end user responsibility center
Integrated versus dispersed is database
System designer shall regard data any kind ingoing in base's data and one turns in at File
Surround Strategy of System Development
Environmentally surrounding strategy is of important in term confiscation because information system of other firm may in contrast to corporate currently.

Tactics option
Done before operational scheme option

Operational scheme option
Scheme option can be agglomerated into
* Input
* Online Off-line Vs Entry Data
* keyed Vs Machine Readable is Entry Data
* Centralized Vs Decentralized is Entry Data
* Processing
* Vs's batch Realtime record update
* sequential Vs direct Access to records
* Single Vs Multiple User is of records's update
* Output
* Traditional Vs Turn Around Documents
* Structured Vs Inquiry based reports


SELECTING THE PROPER SYSTEM

Tactics compares: System than bases cost and gain relatively; There is 3 A's system trick is said more superior with another system if:
* A have inferior cost of B and gain both with
* A have inferior cost of B and A result more gain A lot of of B
* A and b have cost with but resulting gain A more A lot of.

Severally Methodics Komparasi System
* Break Even point Analyisis
* Payback Period
* Discounted PayBack period
* Internal of Return's Rate

Katagori is Cost
* Hardware
* Software
* People
* Suppliers
* Teleccommunications
* Physical sites

Cost detail
Comparing information system cost via system life, projection's analyst gets what change cost for the future and there is 3 information system cost models which is Linear, Exponential and Step Function.

Information system cost can happen really just and gets too happening chronically.
* Happening information system cost once just which is onetime cost and development cost what do happen while system development.
* Happening information system cost continually among those is reccuring cost and operational cost where this cost happens while operating information system everyday.

INFORMATION SYSTEM FACTOR

Kualitatif's factor that aim good information system performance among those
* Reducing fault zoom
* Reducing time to fix fault
* Reducing response time from workstation alternative
* Hastening penyediaan's time information
* Increasing system security
* Increasing record's source update active
* Increasing wearing satisfaction


Corporate strategy factor
* Consumer satisfaction
* Sell zoom increases
* Consumer commitment and vendor
* Product marketing information

PRESENTATION IS SYSTEM LEARNING

Doing presentation in few words

Reducing alae tech explanation detail

Presentation is clear with visual's assistive tool

If utilizes model to utilize assistive tool e.g. laptop so more informative

Emphasize gain of information system proposal with severally alternative whatever available appropriate condition which experienced by firm.

DECISION DRAWNS OUT OR NOT

If firm decides to develop system therefore information department will do succeeding process which is System Design Process.

If contrariwise therefore System Development Life Cycle (SDLC) will be discontinued.

Oft will find problem with studi's system and and usually top management will ask for to do its reworking to studi's system.

Model will word some part step which at reand sometimes information department will make mengulang's decision step before word studi's system.

With alternative, decision for mengulang one SDLC'S step in advance or not been called Go – No. –Go Decision.
