  • Data can take many forms, including traditional alphanumeric data- numbers alphabetical and other characters- text data -sentences and paragraphs used in written communication, image data – graphic shapes and figures & audio data- human voice and other sounds.
  • Def: Information as data that have been converted into a meaningful and useful context for specific end users. Thus subjected to value added process (data processing or information processing) From aggregated, manipulated and organized- calculating, comparing, sorting, classifying and summarizing Content analysed and evaluated Placed in proper context for a human user.
  • Field – grouping charactes representing characteristic of person, place, thing or event- name field Record- collection of interrelated fields- name field, social security no, department field etc. File- collection of interrelated records- payroll file Database- An integrated collection of interrelated records or files- personnel data base- payroll, performance review, carrer development etc
  • Strategies are Cost leadership, Differentiation, Innovation, Growth, Alliance and other strategies.
  • Valuable asset-no. 9. Enhance productivity, stimulate innovative development and improve customer relations.
  • To define problems and opportunities and develop solutions Studying a problem and formulating a solution involve the following
  • Symptom- Sales of a company’s products are declining Problem- Sales persons are loosing orders because they cannot get current information on product prices & availability Opportunity- Increase sales significantly if sales persons could receive instant responses to requests for price quotations & product availability

Select the system solution that best meets your requirement </li></ul><ul><li>4. Design the selected system solution </li></ul><ul><li>5. Implement and evaluate the success of the designed system </li></ul><ul><li>How it help develop solutions to business problems? </li></ul>
    40. 40. Define the problem Develop alternative solutions Select the solution Design the solution Implement the solution
    41. 41. 1. Defining problems and Opportunities <ul><li>First step- Identify problems & solutions </li></ul><ul><li>Problem- A basic condition that is causing undesirable results </li></ul><ul><li>Symptoms- separate from problem are merely signals of an underlying cause or problem </li></ul><ul><li>Opportunity- a basic condition that presents the potential for desirable results </li></ul>
    42. 42. <ul><li>Using systems thinking to understand a problem/opportunity is one of the important aspects of the systems approach </li></ul><ul><li>Peter Senge calls- fifth discipline </li></ul><ul><li>Senge argues mastering ST is vital to personal fulfillment & business success in a world of constant change. </li></ul><ul><li>The essence of ST is seeing the forests and the trees in any situation by: </li></ul>
    43. 43. <ul><li>Seeing interrelationships among systems rather than linear cause-and – effect chains whenever events occur </li></ul><ul><li>Seeing processes of change among systems rather than discrete “snapshots” of change,whenever changes occur. </li></ul><ul><li>Practice- find systems,subsystems& their components of systems in any situation you are studying, this ensures imp. factors and their interrelationships are considered. Systems context, systemic view of a situation </li></ul>
    44. 44. 2. DEVELOPING ALTERNATIVE SOLUTIONS <ul><li>Several different ways to solve problem /pursue opportunity. </li></ul><ul><li>Jumping from problem definition to a single not good idea </li></ul><ul><ul><li>Limits options </li></ul></ul><ul><ul><li>Robs the chance to consider the advantages & disadvantages of several alternatives. </li></ul></ul>
    45. 45. <ul><li>Sources of alternative solutions </li></ul><ul><ul><li>Experience, </li></ul></ul><ul><ul><li>solutions that have worked, or at least been considered in the past should be reconsidered, </li></ul></ul><ul><ul><li>advice of others,including recommendations of consultants and the suggestions of expert systems, </li></ul></ul><ul><ul><li>intuition & ingenuity for creative solutions </li></ul></ul><ul><ul><li>DS software ie, simulation process & </li></ul></ul><ul><ul><li>doing nothing. </li></ul></ul>
    46. 46. 3. Evaluating alternative solutions <ul><li>Alternative solutions evaluated to identify best solution </li></ul><ul><li>Goal of evaluation is to determine how well each alternative solution meets your business and personal requirements </li></ul><ul><ul><li>Requirements are key characteristics and capabilities that one feel is necessary for personal or business success </li></ul></ul>
    47. 47. <ul><li>Criteria may be ranked or weighted, based on their importance in meeting one’s requirements. Eg:- In sales related information problems criteria may be startup costs,operating costs,ease of use,and reliability. </li></ul><ul><li>Finally each alternative solution may be evaluated based on how well it meets your evaluation criteria. </li></ul>
    48. 48. 4. Selecting the best solution <ul><li>Once all AS evaluated,selecting the best solution begins. </li></ul><ul><li>Alternative solutions can be compared to each other because they have been evaluated using the same criteria. </li></ul><ul><ul><li>Eg:- 2 alternatives screened and ranked and selected or rejected based on individual criteria or overall scores. </li></ul></ul><ul><li>Possible that one might not always select the top-ranked alternative for reasons like unforeseen budget constraints,political developments,or legal challenges. </li></ul><ul><li>Doing nothing. </li></ul>
    49. 49. 5. Designing and Implementing a Solution <ul><li>Once solution selected , it must be designed and implemented. </li></ul><ul><li>Help- other business end users & technical staff to develop design specifications & Implementation plan </li></ul>
    50. 50. Design specification <ul><li>Describe the detailed characteristics and capabilities of the people,hardware, software & data resources and information system activities needed by a new system </li></ul><ul><ul><li>Eg:- Computer based sales support system </li></ul></ul><ul><ul><li>Types and sources of computer h/w,s/w to be acquired for the sales rep. </li></ul></ul><ul><ul><li>Operating procedures for the new sales support system </li></ul></ul>
    51. 51. Implementation Plan <ul><li>Specifies the resources,activities and timing needed for proper implementation </li></ul><ul><ul><li>Training of sales reps and other personnel </li></ul></ul><ul><ul><li>Conversion procedures and timetables for final implementation </li></ul></ul>
    52. 52. 6. Post implementation review. <ul><li>Final step </li></ul><ul><li>Implementation solution can fail to solve the problem for which it was developed as even well- designed solutions can be confounded by real world. </li></ul><ul><li>post implementation review process- results of implementation monitored and evaluated. </li></ul><ul><li>Success of a solution-reviewed after it is implemented. </li></ul>
    53. 53. <ul><li>The focus of this step is to determine if the implemented solution has indeed helped the firm and selected subsystems meet their system objectives. </li></ul><ul><li>If not systems approach cycle back to a previous step and find workable solution. </li></ul>
