ASSIGNMENT 1

Q1.What is a system? Explain various System Development Approaches in detail. According to you which approach is best? Justify your answer.
Ans1. A system is a set of interacting or interdependent components forming an integrated whole or a set of elements and relationships which are different from relationships of the set or its elements to other elements or sets. The elements of a system are: * Input and output * Process * Control * Feedback * Environment * Boundaries and interface
There are 4 System Development Approaches: 1. Prototyping Development 2. Rapid Application Development 3. Joint Application Design 4. Participatory Design

1. PROTOTYPING DEVELOPMENT:
Software prototyping refers to the activity of creating prototypes of software applications, i.e., incomplete versions of the software program being developed. In this a prototype is made first and based on it final product is developed. A prototype is a model or a program which is not based on strict planning, but is an early approximation of the final product or software system. This type of System Development Method is employed when it is very difficult to obtain exact requirements from the customer. While making the model, user keeps giving feedbacks from time to time and based on it, a prototype is made. Completely built sample model is shown to user and based on his feedback; the SRS (System Requirements Specifications) document is prepared. After completion of this, a more accurate SRS is prepared.

2. RAPID APPLICATION DEVELOPMENT:

Rapid application development (RAD) is a software development methodology that uses minimal planning in favour of rapid prototyping. It is broader in scope as compared to prototyping. The "planning" of software developed using RAD is interleaved with writing the software itself. The lack of extensive

...Hydraulic Systems Managers should always make sure these systems are always properly serviced and bleed after any maintenance is done to prevent air in the system. Air in these systems may not seem like a big deal, but air is compressible and when entering components, they are weak. The force of air onto a spoiler surface pushes down due to air in a spoiler actuator. Pilots should watch for sudden system pressure and quantity drops, which could be the result in several things such as air that finished its way through the system or a broken component. Air in the lines vibrates and can cause the line to rupture. To prevent this low-pressure system bleed is preferred, exercising all subsystems to push the air out slowly and safely for both personnel and the aircraft. Another key fault to watch for is system demand loads. Both pilots and maintenance alike will power up the hydraulic systems and try to operate every flight control system at once over loading the work load of the pumps causing them to either shell out, crack or the spline shaft of the pump strips out (which is what is supposed to happen to prevent loss of the system). There are all kinds of emergency procedures for these hydraulic systems, some are electrically controlled, some are pneumatically controlled, and some systems have a redundancy system (two systems operating the same component). Electric one is just a switch opening up reserved pressure in an accumulator to operating a sub system one time,...

Organizations as a System.

...Organizations as a system. A system is a whole made up of parts. Each part can affect the way other parts work and the way all parts work together will determine how well the system works. when can look at business organization as a system because it conforms to the system definition; it recognizes the interrelationships of people, processes, decisions and designs organizational structure in order to realize its projected economic goal. An organization with a good designed system will requires an understanding of how all the parts (for instance, HR department, production department, logistic department, finance department, sales department, marketing department, IT department …etc) fit together as a whole, an intimate understanding of the parts themselves for a better understanding of endogenous event and a full awareness of the organization’s environment including the other external systems to which it is connected to better prepare for exogenous changes. Some hypothetical problems that disrupt the balance of the an organization would be a coordination or communication issue between departments, for instance HR department not selecting adequate candidate for a specific job skill because it did not have all relevant information about the job, or for instance marketing department lunches a new product without integrating logistic department in the project which may cause delays of production and order fulfillment issues. Another issue that may disrupt the balance of the system is exogenous...

...A system is a set of interacting or interdependent components forming an integrated whole. Every system is delineated by its spatial and temporal boundaries, surrounded and influenced by its environment, described by its structure and purpose and expressed in its functioning. Fields that study the general properties of systems include systems science, systems theory, systems modeling, systems engineering, cybernetics, dynamical systems, thermodynamics, complex systems, system analysis and design and systems architecture. They investigate the abstract properties of systems' matter and organization, looking for concepts and principles that are independent of domain, substance, type, or temporal scale. Some systems share common characteristics, including: A system has structure, it contains parts (or components) that are directly or indirectly related to each other; A system has behavior; it exhibits processes that fulfill its function or purpose; A system has interconnectivity: the parts and processes are connected by structural and/or behavioral relationships; A system's structure and behavior may be decomposed via subsystems and sub-processes to elementary parts and process steps; A system has behavior that, in relativity to its surroundings, may be categorized as both fast and strong. The term system may also refer to a set of rules that governs structure and/or behavior. Alternatively, and usually in the context of complex social systems, the term institution is used...

Information System

...Information System With the increase in technology driving down the costs of information systems, many businesses are choosing to rely solely on information technology (McCubbery, 2009). The development of information systems and the Internet have revolutionized business operations (DeLone & McLean, 2004). While it is possible to successfully operate a small business without information systems, it is easier and more cost effective to utilize the new technology. Information systems are comprised of two subsystems, each containing two components. The first is the technical system which is made up of technology and processes (McCubbery, 2009). The second is a social system made up of the structure and the people (McCubbery, 2009). The first part of the technical system is referred to by the text as “technology”. This is the hardware, software, and telecommunication equipment used to comprise the information system. This component is responsible for capturing, processing, storing, and distributing information. The process component of an information system is the set of steps or activities that are put into motion by an individual, group, or organization in order to accomplish a task (McCubbery, 2009). Processes will vary from business to business and there can even be more than one process to complete the same tasks since businesses are constantly changing. The first part of the social system is the people. The term “people” refers to all of those that are directly involved...

Organization as a System

...Organizations as Systems A system is a collection of parts (or subsystems) integrated to accomplish an overall goal (a system of people is an organization). Systems have input, processes, outputs and outcomes, with ongoing feedback among these various parts. If one part of the system is removed, the nature of the system is changed. Systems range from very simple to very complex. There are numerous types of systems. For example, there are biological systems (the heart, etc.), mechanical systems (thermostat, etc.), human/mechanical systems (riding a bicycle, etc.), ecological systems (predator/prey, etc.), and social systems (groups, supply and demand, friendship, etc.). Complex systems, such as social systems, are comprised of numerous subsystems, as well. These subsystems are arranged in hierarchies, and integrated to accomplish the overall goal of the overall system. Each subsystem has its own boundaries of sorts, and includes various inputs, processes, outputs and outcomes geared to accomplish an overall goal for the subsystem. A pile of sand is not a system. If one removes a sand particle, you've still got a pile of sand. However, a functioning car is a system. Remove the carburetor and you've no longer got a working car. It is important to look at organizations as systems because the effect of this systems theory in management is that writers, educators, consultants, etc. are helping managers to look at organizations from a broader perspective.

Distributed Systems and Centralized Systems

...Distributed System and Centralized Failures By Kentrell Lanier POS/355 March 28, 2014 Paul Borkowski Distributed System and Centralized System Failures Distributed system is many computers linked together that take on different tasks and act like one big computer. Distributed system is found in business across the world. When computers are linked together they share the same database and server. Distributed system is constructed for resource sharing, computation speedup, reliability, and communication Distributed system have different names for the computers in the system. Names such as sites, nodes, computers, machines, and host. Each names goes to a computer that’s part of the system. Resource sharing is when computers link up and they have different data any user can use the data form any computer in the system. Computation speedup is when the system recognize that one computer is over worked so the system have computers that’s have less duties to perform the tasks. Computation speedup help the system from crashing and tasks are preformed quicker. Distributed systems are more reliable because if one computer crash or fail the others can share its responsibilities and system will continue running smoothly. By computers being link together the users can communicate between each other. Two Types of failure When dealing with computers there are two types of failures. You can have a hard drive failure or a software failure. A hard drive failure is when the disk drive fails to...

System Thinking

...Organizations with functional and hierarchical structure may operate within a closed mechanistic structure with top-down management. Organizations striving to create relevance and competitive advantages may adopt more adaptive, flexible, interdependence and open management strategies. Organizational systems vary and can be simple or complicated; complex or chaotic; and linear or nonlinear. System dynamics in its broadest sense seeks to provide information and knowledge of how relationships influence the behavior of the system (parts and whole) over time. Designing, and managing systems in an ever-changing environment can present leaders with challenges as well as opportunities. Ackoff and Gharajedaghi (1996) defined a system as “a whole defined by one or more functions, which consists of two or more essential parts” (p.13). Systems Theory, Systems Analysis and Systems Thinking examines input, processes, outputs and outcomes, with ongoing feedback. Social systems (groups, supply and demand, friendship, etc.) range from very simple to very complex. Complex systems, are comprised of numerous subsystems are arranged in hierarchies, and integrated to accomplish the overall goal of the overall system.

...Running  Head:    Systems  Thinking     1   Systems Thinking Management Process Systems  Thinking             2   Table of Contents Introduction to Systems Thinking Reflections on readings Applying SIMILAR to an area needing improvement Conclusions Systems  Thinking             3   Systems thinking is a very new concept to me. It is an outstanding approach with a global view of the entire system and not viewing each department as a separate entity thus preventing the siloed effect. First and foremost, I think it is critical to define just exactly what constitutes a system. According the Dr. Deming’s book, a system is defined as “a series of functions or activities within and organization that work together for the aim of the organization” (Latzko, 1995, p. 35). I at first struggled with the systems concept. Using this approach all components of the system gain and not at a cost to another. With that definition in mind we can apply this thinking to any organization or process. I love the analogy Dr. Deming used by looking at an orchestra as a perfect system. My translation of this analogy is that the sum is greater than the parts. The combined efforts of each member of the orchestra are an outstanding product, beautiful music, regardless of the instrument played. All the orchestra members have the same common purpose (Dr. Deming’s 1st point for management). Thus, providing...

Complexity in Systems

...COLLECTED VIEWS ON COMPLEXITY IN SYSTEMS JOSEPH M. SUSSMAN JR East Professor Professor of Civil and Environmental Engineering and Engineering Systems Massachusetts Institute of Technology Cambridge, Massachusetts April 30, 2002 The term “complexity” is used in many different ways in the systems domain. The different uses of this term may depend upon the kind of system being characterized, or perhaps the disciplinary perspective being brought to bear. The purpose of this paper is to gather and organize different views of complexity, as espoused by different authors. The purpose of the paper is not to make judgments among various complexity definitions, but rather to draw together the richness of various intellectual perspectives about this concept, in order to understand better how complexity relates to the concept of engineering systems. I have either quoted directly or done my best to properly paraphrase these ideas, apologizing for when I have done so incorrectly or in a misleading fashion. I hope that this paper will be useful as we begin to think through the field of engineering systems. The paper concludes with some “short takes” -- pungent observations on complexity by various scholars -- and some overarching questions for subsequent discussion.

System Theory

...dynamic process. Marx and Darwin used this theory in their work. System theory (as we know it) was used by L. von Bertalanffy, a biologist, as the basis for the field of study known as ‘general system theory’, a multidisciplinary field (1968). Some influences from the contingency approach can be found in system theory. Core Assumptions and Statements System theory is the transdisciplinary study of the abstract organization of phenomena, independent of their substance, type, or spatial or temporal scale of existence. It investigates both the principles common to all complex entities, and the (usually mathematical) models which can be used to describe them. A system can be said to consist of four things. The first is objects – the parts, elements, or variables within the system. These may be physical or abstract or both, depending on the nature of the system. Second, a system consists of attributes – the qualities or properties of the system and its objects. Third, a system had internal relationships among its objects. Fourth, systems exist in an environment. A system, then, is a set of things that affect one another within an environment and form a larger pattern that is different from any of the parts. The fundamental systems-interactive paradigm of organizational analysis features the continual stages of input, throughput (processing), and output, which demonstrate the concept of openness/closedness. A closed system does not interact with its environment. It does not take in...

The sociotechnical system theory is an approach to understanding the relationship between technology, individuals, organizations and society in work place design. "The sociotechnical systems approach says that a change in one part means there will have to be corresponding changes in other parts. “The sociotechnical systems approach says that a change in one part, means there will have to be a corresponding change in other parts. “The quantitative management approach involves the use of mathematical modeling to find the best solutions to problems. One important component of the quantitative management approach is an ability to objectively collect information about a problem and possible solutions to develop appropriate, and useful, mathematical models. Organizational behavior theory usually represents concepts that help a company create better management practices. Concepts such as leadership, decision making, team building, motivation, and job satisfaction are all facets of organizational behavior and responsibilities of management. Systems theory is a broad perspective that allows managers to examine patterns and events in the workplace. This helps managers to coordinate programs to work as a collective whole for the overall goal or mission of the organization rather than for isolated departments.

I will cover both that I feel will be the most applicable to our record store. I feel that we need multiple systems that will benefit us with accessibility and understanding of the systems, The transaction processing system is the bottom part of the structure to use for the employees because it has many different unique uses. The TPS can collect, store, modify, and retrieve the transactions of an organization. It stores data in certain files that are able to be seen only by select individuals. There will be worker files only accessible by employees as well as manager and CEO files that only we can access. It offers many other useful tools such as rapid processing, batch processing, and real time processing. Management information systems are above the transaction processing system. These systems don’t deal with the day to day data in needing and operating our record store such as the TPS. The MIS provides information that is needed to organize and manage organizations efficiently and effectively. MIS involve three primary resources: people, technology and decision making. The systems main purpose is to analyze operational activities in the organization. It can show if our plans our reaching out goals and allows our managers to supervise over the TPS.
