Faculty Feedback and SuggestionsWork harder
You should not hesitate to undertake hard workYou may have to learn new methods, tools and software packages to get what needs to be doneSD is a major link to industry, let us try not to lose face
TeamworkYou do not have to like each other, but you still have to work together as professionalsBe prepared for team meetingsDistribute load equally among team membersWork done and report sections written by individual members of the team need to be connected

Faculty Feedback and SuggestionsAnalysis of the problem situation
Using IE 398 tools (system elements, boundary and so on) is not sufficientConnect these to work that follows, use other toolsDraw useful conclusions from your analysis
"Haa, demek ki öyle!"
Statistical analysisDescribe data needed from the organization in a precise manner and submit written requests Question and interpret data analysis resultsConduct statistical estimation and hypothesis testing to draw useful conclusions
"Acaba öyle mi?”

Faculty Feedback and SuggestionsPresentations
Presentation skills are above the average, but...Technical content should be strengthened with better system and data analysis (more expected in Spring)More numerical results are needed to support symptoms and problemsGo over your slides with your faculty advisorsUse available time more effectivelyDo not talk fast, stick to the main points but support them betterDo not be defensive, make sure you understand the question before answering itAttend other teams’ presentations

Faculty Feedback and SuggestionsReport writing (more on this later)
Check lists in SD Handbook are not section headingsBegin by preparing an outline of sections and subsections, including figures, tables and appendicesBefore starting, discuss who is going to write what under which sectionMake sure that terminology is consistent throughout the reportAvoid redundant repetitionsEdit and correct on hardcopy before submissionIntroduction and problem situation sections are in particular problematicDo not put all figures and tables in appendices

Important!
The above report organization is given in a “linear” fashion, but remember that system design is “circular” or iterative by natureTherefore, as you do the actual analysis and design work, you will often have to return to the previous steps and revise the contents of Sections 3-7 accordingly
