Marks : 100 Instructions to the candidates : 1) Answer any 3 questions from each section. 2) Answers to the two sections should be written in separate books. 3) Neat diagrams must be drawn wherever necessary. 4) Figures to the right indicate full marks. SECTION - I Q1) a) Why is a MIS as practiced in industry a pyramid structure made up of decreasing complexity information processing layers? Explain preferably with the help of an example. [8] b) As convergence technologies evolve over the next decade (a forecast), a new world will emerge. Analysts predict : [8] Networks will speed up by an average of 50% a year, the historic norm. In advanced world, faster broadband and mobile systems will be strong enough for commuters to check for traffic jams and watch soap operas on their cell phones. In Japan and Korea, this is a reality in 2004 itself, while U.S. will catch up in a decade. By 2012-13, practically every machine in the realm of communications - every gadget that sings, talks, beams images or messages - will sport powerful computer and a network connection. And every bit of digital information, whether it s phone call, a song, a Web page, or a movie, will flow among these machines in the very same river of data. By the end of this 10-year-cycle (i.e., by 2020), the change could be extreme : Web pages will snap to life. Hundreds of thousands of political bloggers, flu fishermen, and chefs will be uploading gobs of video programming creating their own channels. P.T.O. This plethora of Web shows will compete for attention with TV fare, Internet radio, video e-mails and games. All of it will play on televisions, computers and cell phones, which will be different flavors of the same machine. The concept of a network or a channel will go away. They are artifacts of old technology. What do you understand by the term Convergence Technology ? OR Q2) a) The dramatic technological shifts ahead are likely to shakeup age-old concepts at the foundation of economic life. In the coming markets of moving bits, who owns what? Will people buy programming and machines? Or will they rent and subscribe? Innovative companies will sort out these questions, leading the way in building new business models for the coming age. Those who figure out how to reach through the networks to deliver customized information and services will be the architects and kings of the converged economy. Discuss preferably with the help of examples business implications of rise of convergence technology. [8] b) With the help of Figure (1) explain how convergence technology enabled information systems will deliver promised business transformations for business value creation? What will be their relationship with quality information systems? [8] THE PROMISE ENABLING TECHNOLOGY The Internetworked Business The Net Interenterprise Computing: Shift from linear value chain emphasizing value addition to value network emphasizing value generation The Extended Enterprise The Integrated Enterprise Enterprise Infostructure The High Performance Team Workgroup Computing: Lotus Notes, Platform approach. Personal Multimedia: Multimedia computing The Effective Individual THE CHANGE Wealth Creation, Social Development Recasting External Relationships Organizational Transformation Business Process And Job Design Task, Learning Efficiency Fig. (1): Business Transformation Through Convergence Technology [3764]-251 -2- Q3) a) Businesses have changed a lot but given that customer requirements are becoming increasingly local and instant, it is business processes and models that have changed the most . With the help of Figure (2), explain evolution of business models from ad-hoc, open loop business model to a closed loop engineering quality business model to a model describing generic business process as integral to a closed loop information and control system constituting a business process IS view. [8] b) Figures (2) gives a systems view of a business process represented as a generic business process IS view and as integral part of a closed loop information and control system characterized by continuous information origination and processing in the presence of uncertainty and the emergent all encompassing view of Information Integrity for business competitive advantage. Figure (3) models a business process, with a controls interpretation, as integral to a close loop information and control system. Based on Figures (2) and (3) write short notes on any two of the [8] following : i) Uncertainties in business process IS view, ii) Complex error, iii) Information Integrity Risk. OR Q4) a) With the help of Figure (3), describe in your own words an engineering system with its physical variable controls and process controls modeled as an engineering business system with a requirement to meet customer requirement. [8] b) Write short notes on any two of the following (To answer you may refer to Figures (2) and (3)) : [8] i) With external and internal customer requirements becoming local and instant, a system is emerging to be a potential source of information . Explain. ii) In a business IS view, information is function of source, process and recipient . Explain. iii) Shift from data storage and retrieval to information evaluation, storage and retrieval. iv) List the multistage dynamic decision stages constituting the information origination a system undertakes to reduce the uncertainty it (system) experiences about the environment. [3764]-251 -3- [3764]-251 -4- [3764]-251 -5- Q5) a) The system dynamics approach to complex problems focuses on feedback processes. It takes the position that feedback structures are responsible for the system changes over time. The premise is that dynamic behavior is a consequence of system structure. As a result the system dynamics approach looks within a system for the source of its problem behavior. For example, inventories are not assumed to oscillate merely because consumers periodically vary their orders. The system dynamicist takes the view that inventories behave as they do for reasons internal to the system, for reasons pertaining internal structure of the system. In practice, this internal point of view results in models of feedback that bring external agents inside the system. Within the framework of above statement, explain any three of the following concepts in your own words : [9] a) Complex problem, b) Feedback processes, c) Dynamic behavior, d) Bringing external agents inside the system . b) Fill in the blanks by putting in appropriate word from the set of words given at the appropriate blank indicated by number. [9] ______ (1) ______ problems often become so ______ (2) ______ that understanding ______ (3) ______ and ______ (4) ______ responses to policies are ______ (5) ______ without a formal model. For example consider a ______ (6) ______ structure of a police response system. It will have ______ (7) ______ variables such as Crime Rate, Desired Additional Police Effort, Socioeconomic Effect on Crime Rate, Effort Directed against Addict Criminals, Imprisonment Rate, etc. It is far from easy to ______ (8) ______ how such a model would behave when, for example, community awareness of drug problem is ______ (9) ______, and yet such understanding is what we expect of those charged with designing and implementing public policy for real systems. Set of desired words to choose appropriate word to fill in the blank : {anticipate; many; impossible; increased; feedback; behavior; complex; real world; predicting} Note : You may write answer by pairing the number and the word; OR [3764]-251 -6- Q6) a) Define in your own words any three of the following System Dynamics variables : [9] i) Level variable, ii) Rate variable, iii) Parameters and input variable, iv) Supplementary variable, v) Auxiliary variable. b) Fill in the blanks by putting in appropriate word from the set of words given at the appropriate blank indicated by number. [9] A simple ______ (1) ______ feedback loop centering on traffic congestion and highway building could include such ______ (2) ______ as the number of cars or ______ (3) ______, extent of the highway system, traffic congestion, driving safety and comfort and highway construction. As the number of cars or the amount of driving ______ (4) ______, traffic congestion increases, ______ (5) ______ driving comfort and safety. That sets up ______ (6) ______ that lead to ______ (7) ______ highway construction to ______ (8) ______ traffic congestion. The loop is negative because an ______ (9) ______ in traffic congestion eventually results in pressures to decrease (negate) it. Set of desired, words to choose appropriate word to fill in the blank : {lesson, increases, more, variables, pressures, increase, reducing, negative, amount of driving} Note : You may write answer by pairing the number and the word.
