1 IST 552 Syracuse University School of Information Studies Information Systems Analysis: Concepts and Practice Spring 2007 Course Syllabus as of 30 December 2006 Instructor: Kevin Crowston Physical Office: 348 Hinds Hall Phone: +1 (315) Syracuse University Syracuse NY FAX: +1 (866) Class URL: WebCT Helpline: Course Description & Objectives Modern organizations large and small need computerized information systems to function and maintain their competitive edge. Information systems relieve organizations of the burden of slow and cumbersome manual paper-based processes and enable them to conduct business more efficiently and effectively. Information systems analysis is an important step before implementing any computerized information system. Any mistakes made during the analysis stage will significantly affect the later stages of system development and cost time and money to correct. Competence in information systems analysis is crucial to virtually every modern Information Technology professional, including those professionals highly demanded by the market such as Systems Analysts, Business Analysts, Web Developers, Information Architects, Database Administrators, Network Administrators, or Software Engineers. This is why Information Systems Analysis course plays a key role in IT programs worldwide. IST 552 is an introductory course, covering the concepts and techniques of information systems analysis and design (SA&D), including analysis skills as well as managerial issues. The course covers techniques used by modern systems analysts and gives extensive practice with structured methodologies and object-oriented techniques. The course will emphasize: 1. Experiential learning through assignments and projects, 2. Collaborative learning the important concepts, techniques, and skills with peers through class discussions and project conduction. Upon completion of the course, students are expected to be able to: 1. Define various systems analysis and design concepts and terminologies, 2. Describe the stages of the system development life cycle model, 3. Describe different methodologies and state-of-the-art developments in SA&D techniques and methods, 4. Compare, use and synthesize different conceptual modelling techniques for systems analysis (including ERDs, DFDs and UML), 5. Apply logic modelling techniques (decision tree/table, structured English), 6. Address the managerial issues involved in SA&D, 7. Model the importance of collaboration and communication during SA&D.

New York, NY: McGraw-Hill Companies, Inc. ISBN Additional readings may be distributed on WebCT. Software: QSEE SuperLite CASE tool, available free for non-commercial use from Assessment This course provides knowledge and hands-on experience in Systems Analysis. To gain practice and technical skills, class members will engage in discussions, collaborative and individual assignments and group projects. Discussions will assist in the ability to reflect about practical issues and discuss these with colleagues. Collaborative assignments will compliment individual ones as critical skill building exercises. A group project will be the culmination for the course material and provide students opportunities to learn from each other. The following table lists the planned due dates for the various assignments. Note that these dates may be changed with sufficient advanced warning.

3 The following table shows the breakdown of the grade by the type of assignment and the party responsible for the assignment. Type Individual Group Total Problem set Discussion Participation Report Pair and share Project Total Note that many of the skills taught in this course will be reinforced through several alternative presentations: an initial demo, a pair-and-share exercise, an individual problem set and a team project assignment. The goal of these repetitions is to provide several repetitions for you to master particularly important skills. Each of the assessments is discussed in more detail below. Pair and share 60 points total Four pair and share exercises will be assigned during the semester: one each on use cases, data flow diagrams, entity-relationship diagrams and object modelling. These provide an opportunity to practice a particular skill with another student and to learn from critiquing others solutions and being critiqued. For each, an exercise will be posted at the start of the week. During the week, you and another student will jointly work on the exercise (ideally, by using an application sharing program as will be discussed), posting your solution by Thursday morning. You will then have an opportunity to review other pairs solutions to the exercise and comment, as well as to optionally make corrections to your own exercise in response to comments. A solution will be posted at the end of the week, allowing you to check your understanding. Points will be awarded for posting a plausible solution and for comments made critiquing others solutions (but not for the correctness of the solution). Problem sets 320 points total Four problem sets will be assigned during the semester: one each on use cases, data flow diagrams, entity-relationship diagrams and object modelling. These problem sets provide an opportunity to practice a particular skill. Each is worth 80 points and should be completed individually. More detail on the assignments will be provided on WebCT. Project 440 points total The term project provides an opportunity for an in-depth investigation of a specific database problem that interests you, as well as a vehicle for you to exercise and receive feedback on your communication and investigative skills. The goals, therefore, are to become familiar with the techniques of systems analysis and design and to expand your written communication skills. Each team will work collaboratively to propose a new system based on user requirements. Due to the large amount of work involved in a complete project, joint projects with other members of the class are encouraged (teams should be about 4 students). Of course, you must be prepared to deal with the inevitable coordination problems inherent in managing team work. Teams may decide to assign specialist roles to particular members, such as project manager, design specialist, writer or research coordinator. However, it should be kept in mind 3

4 that the object of the course is for students to experience as many aspects of the ISAD process as possible. In some cases, it may be most beneficial for students to aspire to roles for which they feel least prepared. Different components of the project will be due on a regular schedule through out the semester. The intent of the frequent submissions is to keep your project team on schedule, to provide an opportunity to practice the skills being discussed in class and to provide an opportunity for frequent feedback. 1. Project proposal 10 points Mon 22 Jan Each team must provide a brief proposal for the project stating the purpose of the proposed system, the planned sources of information about the topic and the members of the team. 2. Project plan 10 points Mon 29 Jan Your team will prepare a project plan. This plan should give a brief overview of the project and a plan for finishing the project as either a Gantt chart or network diagram prepared using Microsoft Project or another project management application. You can think of the plan as a sort of team contract. Your plan should include: a short (1 page) overview of the project, a list of key deliverables for the project, key due dates, estimated start dates and task durations, and who will do the work. Care should be taken to arrive at an appropriate level of granularity for the tasks. (Hint: simply listing the assignments and their due dates will not be sufficient.) The assignment will be graded based on the following criteria: Completeness and detail of plan. Diagrams accurately describe the process. Diagrams conform to the recommended guidelines and format. All elements are correctly labelled. 3. Requirements report 20 points Mon 12 Feb Your team will prepare a report describing the requirements for your project. The report must be based on original research about the proposed project, not just your current understanding. The assignment will be graded based on the following criteria: Requirements accurately describe the project selected. Completeness of requirements. Correct format of requirements. Data collection approach. Quality of writing. 4. Use case diagram 10 points Mon 26 Feb Your team will prepare use case diagrams for your project following the model of the individual problem set. The assignment will be graded based on the following criteria: Diagrams accurately describe the project selected. 4

5 Diagrams conform to the recommended guidelines and format. All elements are correctly labelled. 5. Data flow diagram 20 points Mon 19 Mar Your team will prepare the top-level and detailed data flow diagrams for your project following the model of the individual problem set. The assignment will be graded based on the following criteria: Diagrams accurately describe the project selected. Diagrams conform to the recommended guidelines and format. All elements are correctly labelled. Diagrams are titled. This report will also include a formal description of the system logic for some part of your project. The assignment will be graded based on the following criteria: Logic is correct for the project selected. Clear which part of project is being modeled (i.e., by referring to a particular part of the DFD). Completeness of logic. Diagrams conform to the recommended guidelines and format. Rationale for choice. 6. E-R diagram 20 points Mon 2 Apr Your team will prepare an entity-relationship diagram and a data dictionary for your project following the model of the individual problem set. The assignment will be graded based on the following criteria: Diagrams accurately describe the project selected (i.e., each data item in the DFD matches the ERD and vice versa). Diagrams conform to the recommended guidelines and format. All elements are correctly labelled. Diagrams are titled. 7. Feasibility report 10 points Mon 9 Apr Your team will develop a feasibility report discussing the feasibility of your system and proposing a possible option. The assignment will be graded based on the following criteria: Report accurately describe the project selected Completeness of analysis Depth of analysis Quality of writing 8. Architecture report 10 points Mon 16 Apr Your team will develop a report describing the proposed architecture for your system. The assignment will be graded based on the following criteria: Report accurately describe the project selected Diagrams conform to the recommended guidelines and format. All elements are correctly labelled. 5

6 9. System interface prototype 20 points Mon 23 Apr Your team will develop a Web-based or Visual Basic prototype of the interface for your proposed system. The system does not have to function, but it should have enough functionality to demonstrate how the interface would work (e.g., data entry screens and fields, reports, help, options, etc.). Separately, submit a document that presents the rationale for your interface design choices. The assignment will be graded based on the following criteria: The interface is suitable for the project selected. Usability of the prototype. Conformance with interface design principles. Rationale for design. Functionality of the prototype. 10. Final project report 300 points Mon 7 May The final project report will include at a minimum: An executive summary Analysis of the existing system or service Business overview of the proposed system Methods used for requirements definition Requirements analysis (based on the reports above) System design (based on the reports above) Alternative solutions considered The report will incorporate revised versions of the systems analysis documents you created and handed in during the semester, but note that these documents support your report, rather than replacing it. Grading of the final report will be based on: Accuracy and completeness of the analysis and design (hint: correct any problems identified from previous submissions) Challenge of system chosen by team Timely submission of work Evidence of collaborative team effort Quality of writing Reports 25 points total Four short reports are required at different points in the course. Project progress reports 5 points each Two individual reports on your team process are required. 1. Team dynamics report. By the start of class on Mon 5 Mar, you should individually submit a one-page report describing the dynamics within your team. This report is intended to help me identify individuals and teams that are having trouble working together before it is too late to intervene. The points for the report are given for submission. 2. Team report. At the end of the semester (Wed 9 May), you will submit an evaluation of your fellow team members contributions to your project team. The assessments of your 6

7 fellow team members will be taken into account in determining your project grade. An individual who in the opinion of the majority of other team members contributes less to the project will receive less credit for the project (including the possibility of no credit in the case of no contribution). The points for the report are given for submission. Peer project evaluation 10 points Wed 9 May Once the final project reports are submitted to WebCT, you will select one to read and comment on. The goal is to provide students with an audience for their reports beyond just the instructor. Evaluations will be grade according to the rubric for discussions shown below. Reflection essay 5 points Wed 9 May Finally, you will individually submit a short essay reflecting on what you learned in the course. A portion of learning comes from reflection. Many times we do not realize all that was learned (or not learned) until we take the time to review the good and the uncomfortable. Your one to two page essay reflecting on the learning and experiences from this course should include: Reasons for taking the course in the first place; Objectives for learning (what you wanted to learn, expectations); Did you learn what you wanted to learn; Most valuable thing you learned; Least valuable thing you learned (and why); What you learned that will help you in your next group project; and What you learned that you will definitely not do in your next group project. I suggest you record the first items early in the semester so they are not distorted by your later experiences. You may find it helpful to keep a diary that you update weekly so you can see what you ve learned and how your view of the subject evolves (space will be made available on WebCT). The points for the report are given for submission. Please note: your essay will be the last item I read before I assign your final grade. Discussions 45 points total In addition to the general class discussions, there will be three separately graded discussions during the course: an initial ice-breaker the week of 21 Jan, a discussion of systems analyst careers the week of 4 Feb and a discussion of the impact of new technologies and architectures on systems analysis the week of 8 Apr. Each discussion will be worth 15 points (in addition to the general discussions that are graded for participation). Contributions to discussion will be graded based on the following rubric from Palloff, R. M., & Pratt, K. (2003). The Virtual Student. San Francisco: Jossey-Bass. 0 6 points Minimum number of postings not met. 9 points Minimums met; all discussion on Level I 11 points Minimums met; at least one example of discussion above Level I 13 points Minimums met; at least one example of discussion above Level I with at least one above Level II 15 points Minimums met; at least two examples of discussion above Level I with at least one above Level lli 7

It is important that you make a good faith effort to contribute to class discussions. This means that you need at least a few substantive contributions to the discussion during the week to receive full credit for participation. 45 points of the participation grade will be assigned at midsemester and the remainder for the second part of the semester, based on the rubric above. 8

9 Prerequisites: This course has no prerequisites. IST Statement on Academic Integrity: Course policies Undergraduate, graduate and doctoral students enrolled in IST courses are required to follow the guidelines for academic honesty described in the School of Information Studies Statement on Academic Integrity, available: in any IST Student Handbook, on the Web or on request at the IST Student Services Office. Academic dishonesty includes but is not limited to plagiarism, cheating on examinations, unauthorized collaboration, multiple submission of work, misusing resources for teaching and learning, falsifying information, forgery, bribery, and any other acts that deceive others about one s academic work or record. Students should be aware that standards for documentation and intellectual contribution may depend on the course content and method of teaching, and should consult instructors for guidance. Sanctions for academic dishonesty may include but are not limited to the following: requiring students to re-produce work under the supervision of a proctor; rejecting the student work that was dishonestly created, and giving the student a zero or failing grade for that work lowering the course grade giving a failing grade in the course formal reprimand and warning disciplinary probation administrative withdrawal from the course suspension from the University or expulsion from the University. Instructors who impose sanctions must notify the student promptly and indicate any formal or informal hearing procedures available. Students accused of academic dishonesty have the right to challenge accusations. For IST 552, you are permitted and encouraged to discuss course material with your classmates, especially regarding group assignments. However, individual assignments should not be worked on in a collaborative manner. Special consideration: Students who may need special consideration because of any sort of disability should the professor for appropriate accommodations. WebCT Information: On the WebCT homepage ( you will find links to student FAQs, troubleshooting tips, tutorials, and other information that may prove useful for both new and experienced WebCT users. As students are responsible for being fluent on this educational platform, it is recommended that you review these resources as necessary. 9

10 Organization of the class week: Unlike a face-to-face class, this course requires students to actively participate throughout the week in discussions and activities. As there is no formal class meeting time, it is expected that students will do their readings, view any multimedia presentations, and contributed actively to discussions. Please be advised, this is not a self-paced course, so it is essential that students maintain their work load accordingly. Conduct of discussions: It is expected that students will behave professionally both in language and attitude when posting or responding to discussions. Public disparagement of your fellow students in this course is unacceptable and may result in disciplinary action. Additionally, discussions should model your ability to think critically about course topics and articulate ideas clearly. Responses should be detailed and explanatory. Simple, unconstructive replies such as I agree with the previous post will not be considered valid posts unless elaborated upon. If you have any concerns regarding the suitability of a post, please contact the instructor. Guidelines for preparing assignments: Prepare a professional document. Include tables and graphs that support your content where appropriate. When you prepare assignments be sure to provide proper bibliographical information for any sources referenced, for direct quotations and for the source of key concepts or ideas. Any citation format is acceptable (I personally use APA format), as long as it provides sufficient information for a reader to find the source (i.e., authors names, title of article or book, title, volume and issue of journal (if appropriate), page numbers, publisher, date of publication). If you cite a webpage, be sure to indicate the URL and the date on which you accessed the page, as pages do change. Failure to cite sources is considered plagiarism and subject to sanctions ranging from being required to redo the assignment through expulsion (see above). If you have any questions about what must be cited or how to cite, please feel free to ask. In addition to punctuality, grammar, presentation and ability to follow instructions are very important, as in the real world. If your work does not meet professional standards, up to 30% of your score may be deducted. It is essential that you spell check and proofread your documents. In assignments you may be asked to offer opinions. As with discussions, simply stating your opinion does not constitute a complete response. You must support any opinion with arguments and evidence. Assignments are due as defined in the syllabus unless otherwise specified. The penalty for late assignments will be 10% within the first 24 hours, and an additional 25% for each week thereafter. An exception to this rule is possible in an extreme circumstance in which there is no reasonable way to anticipate or control the situation. Computers crashing, viruses, lost files, etc. are specifically not grounds for an extension at this point in your professional careers, you should know how to manage your technical infrastructure. According to Family Educational Rights and Privacy Act, all student work produced as part of this course may be used during this semester for educational purposes. Later use of this work is also permitted providing either the work is rendered anonymous or if the student provides 10

11 written permission for such usage. If you do not wish your work to be used even if rendered anonymous let me know and I will not do so. Grades If you wish to discuss a grade, hand in a written explanation of your argument and arrange for a private conversation. Except for unusual circumstances, no appeal for an individual assignment or project will be considered more than two weeks after the graded paper is returned. For final course grades, no appeal will be considered more than two months after the final day of classes. It is unfair to allow some students additional opportunities, such as extra credit assignments, without allowing the same options to all students. Accordingly, extra credit assignments are not possible. According to the grading policy of the School of Information Studies, a basic grade will be awarded for student performance that is judged to be satisfactory for the course level (undergraduate or graduate). All other grades will be determined in comparison with the standards of the basic grade. For graduate students the basic grade is B. Fulfilling the requirements for an assignment coupled with the absence of errors (in writing, arithmetic, formatting) will earn a grade no higher than B+. To earn an A- or A grade, the assignment must go beyond the minimum expected in terms of quality (e.g. insight, creativity, analysis, thoroughness, synthesis). An incomplete grade, I, can be given only if the circumstances preventing the on-time completion of all course requirements were clearly unforeseeable and uncontrollable. If an incomplete is required a written contract must be completed which specifies the nature of the missing work, the date it will be completed, and the default grade that will be given if that deadline is missed. Failure to complete any course requirement will result in a course grade of B or lower, regardless of the grades received in other components. 11
