- 2. Joe and Noël have just gotten engaged. As they are both business students, they thought they'd try to plan their wedding preparation as a project. Here's the WBS they've determined is necessary for a simple but elegant wedding. Assume all durations are deterministic. Although perhaps not realistic to real wedding planning, by using the standard calendar in Project Libre (use default working days in software).

Activity 'K' is a critical activity B. Activity 'K' is not a critical activity3- For the following test marketing project at week 6:a. Ignore the far right “% Complete” column and using the 50–50 percent completion rule for PV and EV, calculate the cost, schedule, and time variances. Also calculate the CPI, SPI, CSI, and the ETC and EAC. b. Repeat the calculations in a, but now using the “% Complete” column. Assume that the PV values are based on time proportionality but the “% Complete” values for EV are from the workers actually doing the tasks.
- Outline the steps involved in identifying the critical path of a project. Briefly describe each step 2. Listed below are tools used for project scheduling. Briefly describe each Time sheets Task lists Shared calendars Automated scheduling tools 3. Answer the following questions about work breakdown structures (WBS). Briefly explain what a WBS is. How does the WBS help determine project deliverables? How does the WBS help determine the sequence of activities on a project?Which one is NOT a basic output of a PM network analysis? Select one: a. Identification of the critical path(s) b. Immediate predecessors c. Determination of the earliest and latest start times d. Estimated project duration2. a) The activity shown in Table Q2 (a) are processes carried out in a mechatronic company. Based on the table provided, (i) Determine the Critical Path and Project Duration to complete the process. ii. Activity F cannot start immediately after activity C. The delay is expected to be 7 days. Determine by stating the possible problem, Critical Path and Project Duration to complete the process.
- Answer the following questions with correct options 1. Slack is the length of the time of an activity which can be delayed without delaying the entire project.it must have a value of zero. Equation of the following is to be used in calculation of the slack A) slack= LS - ES B) slack = LF - EF C) slack = ES - EF D) A&B 2, product strategy options are A) differentiation B) high cost with good quality C) A&B D) all of the above 3. Earliest finish time rule A) EF= ES + LS B) EF= ES + LF C) EF = ES + activity time D) ES = EF + activity time 4. Idea development selection does not affect A) product cost B) customer satisfaction C) manufacturing and quality D) none of the aboveThe following represents a very simple project. The calendar allows for 5 work days (M-F) per week. To keep things simple we won’t separate capital expenses and labour. The cost per activity shown below is total (i.e. not per day). Activity Duration (days) Precedent Cost A 5 None* $500 B 7 None* $1000 C 3 A , B $400 D 4 C** $500 E 6 C** $800 * Except for ‘Start’ ** The project can only be signed off once D and E have been completed. Enter the data into a software tool such as GanttProject, and generate the Gantt chart. Please ensure that: 1.…The following is NOT one of the advantages of CPM and PERT:a) Straightforward concept and not mathematically complex.b) Graphical networks help highlight relationships among project activities.c) Critical path & slack time analyses pinpoint activities that need tobe closely watched.d) Project documentation and graphs point out who is responsible for variousactivities.e) Precedence relationships must be specified and networked together.f) Applicable to a wide variety of projects.
