Quick Review




QUICK REVIEW ON STEPS IN SYSTEMS DEVELOPMENT ACTIVITIES

1. INITIATION STAGE
- FIND A PROJECT / UNDERSTAND THE CASE STUDY
- Propose a feasibility study indicating :
Time to produce the systems
Who will produce it
A deadline (expected completion date)
Budget
Etc….etc….
      Feasibility study
      To decide whether the proposed system is feasible usually in terms of economics to
      give estimates of development cost, development timescale, running costs.
      Method: Observation, Interviews, Professional judgment
      Deliverables:
      • Feasibility study report to the sponsor
      • Project plan
      • Cost and benefits
      • The go ahead-or otherwise

2. ANALYSIS STAGE
Requirements Analysis
Gathers information about what the users want in the new systems.
Get also information on the current systems
Systems Analysis
Find out what is done and why it is done, records all events/activities
Generate models (diagrams) showing who does what, when ??(physical model)
Refines your model on requirements, add more details
Generate new model showing just what is done(logical model)
Check your analysis with the users
Deliverables :
Requirement report,
revised plan,
revised costs and benefits

3. DESIGN STAGE
Systems Specifications
States what the new system will do (context diagram)
Generate logical diagrams for new systems (level 1 , 2 diagram DFD)
Defines processes at all levels (lower levels DFD)
Defines all data required (data base design/tables)
Systems Design e.g:
How the new system will fulfill specifications
Which part will be done by computer / which will be done manually?
What size/type of computer?
Use of networking and comms ?, web base / stand alone ?
Design interfaces (GUI)
Data base design (include from your database class --- optional if you don’t develop the real prototype)
Programs/process Specifications
Describe processes using structured English, pseudo codes/decision table
Deliverables:
Systems / software specifications
Programs specifications
Database definitions
Training manuals / help
Hardware specifications if necessary

4. IMPLEMENTATION STAGE
Implementation and unit testing
Systems development
Final definition of data structures
Creation of database tables
Coding of all programs and modules
Unit testing (0ptional)
Conduct unit testing
Systems Testing (optional)
Integrates all units / modules and conduct systems testing

5. OPERATION AND MAINTANAINANCE STAGE
Fixing problems, do improvements, keeping systems up to date, and continuous
upgrading of the systems.

Project Group


PROJECT (25%)

Marks Distribution:
   Reports and all documentation materials (10 %).
   Systems Analysis & Design include user  Interface Design (10 %).
   Presentation (5 %).

INSTRUCTION:
1.   You may choose any system that you already discussed in your group.
2.   A full system analysis & design has to be designed by the end of the semester.
The project is divided into TWO sections:

1) Section ONE : UNDERSTANDING ON CURRENT SYSTEMS (AS-IS)
Students must be able to apply INFORMATION GATHERING TECHNIQUES (ex: interviews, observation, questionnaires, document analysis etc.) in order to understand the current information system. You are required to produce a GANTT CHART, Organizational structure, context diagram, level-0 logical data flow diagram (or more levels), interview’s report, questionnaires report. To conclude the findings you must produce a PROBLEM DEFINITION REPORT (PDR) OR ALSO CALLED the Systems Proposal/requirement definition document which compiles all materials required for the current system.

2) Section TWO : UNDERSTANDING THE NEW SYSTEM (TO-BE)
In this section, students must be able to propose some improvements (ex: business automation, business improvement, etc) on the current system by producing the blueprint of the new system. For this purpose, students are required to apply DATA FLOW DIAGRAM(DFD) techniques when introducing the new features of the proposed system. Based on NEW CAPTURED REQUIREMENTS, students should be able to propose a CONTEXT DIAGRAM for the TO_BE system and be able to convert logical DFD of current systems to the logical DFDs of NEW system with completed partitioning. Besides, students are also required to design INPUT and OUTPUT DESIGN (example Screen, form etc) of the proposed system. Similar to section ONE, all materials such as designs and findings should be compiled and reported in what we called as the DESIGN SPECIFICATION REPORT (DSR).

1.1.2. System name : Sistem Analisis Peperiksaan Sekolah 
Description : Parents or guardians of high school students can now check the results ( Mid Year Examination, Final Examination , and trial UPSR , PMR / SPM PT3 ) and test their children online through the website of School Examination Analysis System ( SAPS ). The system will display the result slips and examination scores . It can be helping parents to make sure children excel in their academic performance monitor . SAPS is preparing a review of the degree of Primary 1 to Primary 6 for primary schools. While for secondary schools it is only a revision of Form 1 , 2 , 3 , 4 and 5 .
To ensure examination results have been updated during the review , be sure to check after the required marks .
