System executant consists of seven groups, that is:
a. User
User is an executant above all because system is created for user and pass communication with system user is made and designed up to achieve latest form. In general user is divided to be three kinds, that is:
• Operational, important how does the colour, like to what the input ware and another specific matter (usually user not intimate with system as a whole and inclined more up at system according to detil)
• Supervisor, important how them can supervise system work and how user performance to operate system.
• Executive, in general they not too intimate and related directly with system development. usually label this is more have an interest in in character strategic and system concept globally, for example chances to competition, new product that can they get from new system.
b. Management
Usually consist of three management kinds, that is user management (handles where does new system applied), system management (involved in that system development self) and general management (in concerned in system design strategy and decision taking supporter system).
c. Inspector
System size that done and where is system at implementation can determine conclusion necessary not it inspector. Inspector usually determine all a certain it based on standard size at develop in many company of a kind.
d. System Analyst
The functions: as archaeologist (that trace to how actually long system walks, how does system run and every thing that concern long system), inovator (help to develop and open user insight for possibilities other), mediator (run communication function from all level that is user, manager, programmer, inspector and another system executant may be not yet has attitude and manner looks at same), officer (as staff experienceder from programmer and indicated in job in advance before programmer work)
e. System Designer
Designer system gets system analyst result (user need doesn't correlating orientation in certain technology), then will be transformn to high level architecture design and not at formulation by programming.
f. Programmer
After system analyst gives the work result and then cultivated by a new system designer, programming can begin.
g. Operation Staff
have a duty and responsible at computer centre (for example : network) , hardware security, software security, printing and back-up. sometimes this system executant is really is not need because system that walk not big and doesn't want special qualification to run system.

Kinds Of System
Basically system is divided two kinds, that is natural system likes sun system, system outside sky, reproduction system and other as it; second, human product system likes law system, library system, transportation system and other as it.
System that be studied is otomation system , be part of human product system and interacted or controlsed by one/more computer as part from system that used in modern society. Otomation system divided in a few category, that is:
a. On-line systems,
System that get directly input in area where do they insert and produce product (that can be in the form of computation result) in area, where are they need. area self can be separated in for example scale kilometer, usually used for reservation air transport, banking and others.
b. Real-time systems,
System that controlling mechanism, data recording and processing very fast with result that acceptable during relative same. The difference with system on line time unit that used real-time usually centesimal or as thousandth as second while on-line still in scale second. Used for system airport traffic controller, guided missile and others. Another difference; on lino usually interacted with user, while realtime interacted with user and environment that mapped.
c. Decision support system + strategic planning systems
System that processed organization transaction daily, help managers takes decision, evaluate and analyze organization aim. used for system of pay, order system, accounting system and production system. Usually formed statistics package, order package and others. this system not only transcribes and display data but also mathematic functions, statistics analysis data and display information in the form of graph (table, chart) as conventional report.
d. Knowledge-based systems
Computer program that made to approach ability and erudition a expert. usually used hardware and special software likes lisp and prologue.

Classification Of System
System classifieds to be several kinds. That is a system classification.
a. Deterministic System
certain system has operated with behavior that can be predicted, interaction between parts can be detected categorically so that the product predictable. example: computer program, carry out correctly as according to the instruction series. system of pay, and
b. Probabilistic System
System that input and the process can be defined, but output that produced can not categorically; (always there a little error or anomaly towards prophecy the way system). example: marketing system
c. Open System
System that connected and influenced with environment outside it. this system gets input and produce product for environment outside or the other subsystem, so that must has good control system. this system is inclined has adaptation character, adaptable with the environment so that can devolve the existence. Example: system in company has adaptation ability (business in face of market rivalry that change. will company inadaptable self alone).
d. Closed System
Physical system where process that doesn't experience matter transfer, energy or information with environment outside system. this system works automatically without interfere in existence from side at outside it. Example: chemistry reaction in isolation tube and closed. Closed system but not closed absolutely to get influences other. this system in the operation can get influence from outside that defined in certain limits. example: computer system (this system only has got input that determined previous, cultivate it and give product also determined previous, not influenced by fluctuation outside system)
f. Artificial System
System that copy insident in system. this system is formed based on insident at where is human not can to do it. In the other word imitation exist in nature. Example: system artificial intelligence, that is computer program that can to make computer impressing think. System robotic and others.
g. Natural System
System that formed from insident in nature. example: sea, solar system and others.
h. Manned Sistem
System that explain behavior that cover character with human. This system can be described in manners as follows:
• human system - human, system focus in connection delivers human
• human system - engine, system that invite engine to a aim
• machine system - engine, automatic system where has task to begins and end system, meanwhile human is involved also to monitor system. interacted engine mechanically to does several activities. this automation makes to increase the important organization concept, where is human released from routine duties or physical duties heavy.

Characteristics of System
Definition
to define system there two approach that used that is approach procedure and approach element.
approach procedure:
system is a network from procedures mutual connected, gather together to do a activity to finish a certain target. procedure operation series klerikal (writing), involve several persons in one or more departement that used to guarantee handling uniform from business transaction that with to finish a certain activity. sequence activity be used to explain to what that must be done, who do it, when done and how do it.
approach element:
system is a collection from interacted elements to achieve specific-purpose.
Characteristics of System
System has characteristics or certain characters, that is:
a. Components
consist of amount of component interact, and cooperate to form one unitary. components can consist of several subsystems or sub-part, where every subsystem has special function and will influence system process as a whole.
b. Limitation
system limitation is region that limit between a system with the other system or with environment outside it.
c . Environment
outside environment from a system whatever outdoor system limitation that influence system operation. environment outside system can has beneficial and can also harm.
d. Liaison
liaison is a media between one subsitem with the other subsystem. pass this liaison makes power sources flows from subsystem to the other subsystem.
e. Input
energy that putted into into system. input can be in the form of maintenance input and signal input. example in computer system, maintenance input is a program and signal input is a data.
f. Output
Result from energy that processed and classified to be useful product and exile remainder. example for computer system, hot that produced exile remainder, while information useful product.
g. Process
A system can has a processor part that will change input will be product. example: accounting system will processed transaction data will be financial statement and reports other that wanted management.
h. Objectives
a system certain has aim or target. target from system very determine once input that wanted system and product that be produced system. field goal covers vast scope, while objectives cover narrow scope.
