...option for someone just starting a project for the first time and if it’s small would be the activity-on-the-arrow diagramming, because each element is represented with a different symbol. I, personally, think that the activity-in-the-box approach is all so usable because the words are boxed off, so you are not going to get things mixed up that easily, unless you are stupid, just saying. 3. Alright, this was a little difficult. I will attempt to explain my findings. I figured the following: * Earliest start time: 19 days * Earliest finish time: 18 days (how this happened, I don’t know) * Latest start time: 47 days * Latest finish time: 47 days I found the latest ones by adding the activities one by one, assuming that would take the longest, in order, of course. Like a to b, b to c, c to d, etc. And in reverse as well, like j and I to the next ones. For the earlier time, I assumed that each activity did not have to have the help of the others because it was a separate activity. So if one activity was moved to the next activity, it would “clear the path” for any other following activity so it could move along more quickly, I’ll explain a little bit more in detail: Start to finish: 1. After 4 days, B moves to F 2. 1 day later, A moves to D, E, C (F 3) 3. 3 days later, C and F move to I (D 1, E 3) 4. 1 day later, D moves to G and H (E 2, I 5) 5. 2 days later, E moves to H (I 3, G 3, H 4) 6. 3 days later, I goes to finish, G moves to J (H 1) ...

...time. Mostly this kind of expedition occurs from the non critical activities where the slack is available. Having done the crash, it would result better utilization of recourses but the rule of thumb is there should not be any major impact on the project scope. In simple terms, this refers to the compression of the original project schedule in order to minimize the total time of the project. This has to be done after very careful study since it might crack the whole project till up to the abandons. Moreover detail analysis and total acceptability of the stakeholders has to be met and this has to be done at the least additional cost. The regain value should be derived from the benefit gain over the additional cost; which has to be realized in positive node with respect to the aggregate impact on the organization. Q2 What are the steps involving in Project Crashing? First, the marginal cost has to be calculated in relation with the project crash for each activity. Crash Cost Per Time Period or Margin Cost= Marginal Cost = (change in cost)/(change in time) = (Crash cost - Normal cost)/(Normal time - Crash time) This has to be calculated in line with the project activity list. Secondly finding the current critical path and way to crash the project at the lowest possible cost is the prominent task. To do so, Identify the critical path in the project net work, mark the critical activities find the lowest cost to crash the project by adding one time period...

...weed-harvesting equipment that is used to clear small lakes of weeds. George Monohan, president of Monohan Machinery, is convinced that harvesting weeds is far better than using chemicals to kill weeds. Chemicals cause pollution, and the weeds seem to grow faster after chemicals have been used. George is contemplating the construction of a machine that would harvest weeds on narrow rivers and waterways. The activities that are necessary to build one of these experimental weed-harvesting machines are listed in the following table. Construct a network for these activities. ACTIVITIES IMMEDIATE PREDECESSORS A B C A D A E B F B G C, E H D, F #2 After consulting with Butch Radner, George Monohan was able to determine the activity times for constructing the weed-harvesting machine to be used on narrow rivers. George would like to determine ES, EF, LS, LF, and slack for each activity. The total project completion time and the critical path should also be determined.

...The activity network diagram is a method of displaying the timelines of all the various subtasks that are involved in any project.[1] Basically, two kinds of activities are required in the network diagram. There are activities in series and activities in parallel. For example, in the diagram of Question 1, Step A and Step B are activities in series and Step C, D, E and F are activities in parallel. For activities in series, Step B cannot start before step A finished. But for activities in parallel, like Step C, D, E and F, all of them are did at the same time. http://www.pmhut.com/critical-path-mapping-with-activity-network-diagrams [pic]G. 1 As G. 1, the first box on the top is Early start time(EST) and the next is Duration time(DUR). So EST plus DUR is the early finish time(EFT) and the EST in the next step as well. Last start time(LST) is different between Last finish time(LFT) and DUR. Total float(TR) between LST and LFT is LFT minus EST and DUR.[2][3] [2]http://www.youtube.com/watch?v=_4m3tZ_TuTg [3]Project Management, Field and Keller (2007, p197, p198 and p391) Question 3: (Words: 136) Duration is the period required to complete an activity, job, or task, usually excluding holidays and other non-working days.[4] For example, in the activity C, duration is ‘10’ between EST and EFT.

Students may be encouraged to do activities on their own with peer group to ensure higher level of participation. • There are ten different tasks to be completed in the course of 96 hours. On completion of each task, record the result and the marks along with the initials of the learner for future reference, inspection and evaluation. • A few activities are suggested under each task. Teachers can improvise on the list and add more activities as they progress from one batch to another. • Students should not be compared with each other; instead they must be compared to the standards given against each task. • The standard suggested is minimum requirement,...
