Investigation System Concept
- Discrepancy of difference between target system and condition system in fact.
- Report detect problem not really real
- target too ideal
- Lacking resource or attitude
- Measurement system less accurate
- Target system which have remainder
- Difference between ideal system and while system
- Problem Solving :
- explain system which run
- Getting ideal system consensus
- Developing some alternative
- Chosen best alternative
Target Investigation à showing the problem of which in fact happened
Problem on the Investigation System
- Time
- Expense
- Knowledge
- Politic
- Interference
Result from investigation is a containing recommendation for example:
- not bring an action anything
- do the maintenance system
- Improving ability or skill of user
- Considering system modification totally
- Placing problem that happened into system development plan which immediately done
Investigation Tactics
- Why we need tactics?
- Finding all problem
- Know about the causes of the problems
- Get the right solution
Investigation tactics needs to do so that the system elements can accept the solution offer without disturbing their activity.
Some tactics can do?
- Listen the opinion from user system
- Don’t give early solution
- Compare the story from some user system to same case
- Pay attention to inconsistention logical problems
Live:
- Questioner
- Interview
- Observation
Non Live:
- Procedural flow
- Document Studying
- Sample
- Tabular
Current Description System:
- Input
- Output
- File
- Data Element
- Transaction Volume and Document of action
- Data flowing chart
Analysis need
The intensive interaction part between system analysis and end user where the development team show their ability to get a good response and gain trust from the user so that they get a good participant.
4 purposes to be achieved:
- Explaining the system briefly
- Drawing an ideal system information
- Bringing an ideal system information to the current condition by paying attention to the resource problem
- Giving a support to the user’s trust into system development
Method:
- Interview
- Questioner
- Observation
- Analysis procedural
- Document Observation
Resource Problem:
- Time
- Money
- Skill
- Technology
- External Factor
Document for analysis need:
· Analysis direction: the relationship between end user, observation process, problems in collecting data.
· User need: the real need, the report need, the training need, and new system influence.
· System’s problem: explain about the problems in time and cost, skill, technology and external factor.
· Documents in form of data collection, statistic consensus, data flowing in physic and logical, data element in the beginning of data’s dictionary.
How to getting close to current system condition with an ideal system condition?
- Making an alternative to solve the problems of the information system.
- The best alternative then applied wisely.
Strategy’s choice
- Distributed versus centralized processing
The changing of information decision from centralized data processing to decentralized end user responsibility center
- Integrated versus dispersed database
The system maker should consider what data that can get into the database and get into the file.
- Surround Strategy of System Development
The environment that surrounds the important strategy in overtaking a company because the system information from other company might different with the current company.
Tactical choice
Tactical choice is done before the operational designation choice.
Operational designation choice
Designation choice can be divided into:
- Input
- Online Vs Off Line Data Entry
- Keyed Vs Machine Readable Data Entry
- Centralized Vs Decentralized Data Entry
- Processing
- Batch Vs Realtime record update
- Sequential Vs Direct Access to records
- Single Vs Multiple User update of records
- Output
- Traditional Vs Turn Around Documents
- Structured Vs Inquiry based reports
Comparing tactic: the system is compared based on the costs and the advantages relatively. There are 3 system ways that can be said better than the other system if:
- A is having a lower cost than B and the advantages of both system is the same.
- A is having a lower cost than B and A is producing more advantages than B.
- A and B are having a lower cost but the advantages that produced by A is better.
Some system comparison method
- Break Even point Analyisis
- Payback Period
- Discounted PayBack period
- Internal Rate of Return
Cost category
- Hardware
- Software
- People
- Suppliers
- Teleccommunications
- Physical sites
Cost detail
To compare the system information cost through life system, an analysis to give a brief explanation on how much the cost for future and there are 3 model of system information cost, which is Linear, Eksponensial dan Step Function.
System information cost might happen only once and might happen continously.
- System information cost that happen only once is ontime cost and development coost that happen when developing the system.
- System information cost that happen contiously is reccuring cost and operational cost where these costs happen when the system operates daily.
Qualitative factor that point to the good system information, such as:
- Reducing the error
- Reducing the time to solve the error
- Reducing the response time from alternative workstation.
- Fastened the time to supply information.
- Increasing the security system.
- Increasing the active record resource updates.
- Increasing the consumer’s satisfation.
Company strategic factor
- Consumer’s satisfaction
- Selling product is increased
- Commitment between the vendor and consumer
- Product information marketing
Presentating the learning system
- Do a short presentation
- Minimalizing a technical explanation with detail
- Presenting brielfy with the visual helping tool
- If using a model then use a helping tool such as notebook so that it can be more informative
- Point out the advantages from system information suggestion with some alternative that suits with the condition that occur in the company
The decision to continue or not
- If the company decides to develop the system then the department of information will process the next step which is system design process.
- If the opposite occurs then System Development Life Cycle (SDLC) will be stopped.
- Sometimes there
- Model will explain some part that repeatedly and sometimes the department of information will make a decision to repeat the part before explaining the system study.
- With some alternative, the decision to repeat a previous part of SDLC or not be said as go – no – go decision
