NFORMATION SYSTEM DEVELOPMENT

System development process
System development process is a set of activities, methods, best practices, goods for delivery, and automated equipment used in the steakholder to develop and continually improve information systems and software.
Capability Maturity Model
CMM framework for systems and software designed to help organizations improve the maturity (maturity) the processes of development of their system. CMM is organized into five maturity levels:
- Tingkat1-start: at this level, system development projects do not follow consistent processes. Each team TODD development tools and methods of their own.
- Level 2 - can be repeated: at this level, the project management processes and practices established to track cost schedule, can the functionality of the project ..
- Level 3 - defined: At this level, the standard system development process (metologi) purchased or developed. All projects use a tailored version of this process to develop and maintain information systems and software.
- Level 4 - Managed: At this level, these goals can be measured for quality and productivity was formed.
- Level 5 - optimized. At this level, the process is continuous development of standardized systems, monitored and improved based on measurements and analysis of data ..

Against Lifecycle Methodology
The life cycle is factoring the useful life of a system of information into two stages (1) penegmbanagan system and (2) operation and maintenance sistem.Ada two-stage life cycle which is a key event that triggers a change from one stage to other stages, namely;
1. when the spin system from development to operations and maintenance, a conversion must occur / appear.
2. at a time, obsolescence appears and a rotating system of operation and maintenance to re-thresholded.
FAST is an acronym of Methodology Framework for the Application of Sistems Thinking (Framework for the application of systems thinking). An intelligent framework fleksibeel enough for a lot of similarities denagn book-based methodologies and commercial practices will be found preformance.
BASIC PRINCIPLES OF SYSTEM DEVELOPMENT
• Principle 1: Involve the User System
• Principle 2: Use a Problem Solving Approach
• Principle 3: Establish phases and activities
• Principle 4: Document Throughout Development
• Principle 5: Establish standard
• Principle 6: Process and Project Management
• Principle 7: Information System confirmed as the Capital Investment
• Principle 8: Do not be afraid to cancel or revise scope
• Principle 9: Divide and Conquer
• Principle 10: Design a System for Growth and Change
System Development Process
Development projects driven by a combination of problems. Opportunities, and orders.
Developed a useful framework to classify the problem, namely PIECES;
P: the need to correct or improve performance
I: the need to correct or improve information utnuk
E: the need to correct or improve the economy, controlling
costs, or meningklatkan keutungan
C: the need to correct or improve the control or security
E: the need to correct or improve the efficiency of people and processes
S: the need to correct or improve service to customers, and
others.
Classical Project Phase
Definition of scope.
There are two purposes of the definition of the scope
1. he answered the question, "Is this project worthy of note?"
2. and assume that these issues deserve attention, it determines the sizes and boundaries of the project, the project vision, all restrictions or limits, project participants are required. And finally, budget and schedule.
