Project Management Network diagram - Essay Example An event is defined as the starting or ending point for a group of activities and an activity is the work required to proceed from one event or point of time to another.(Kerzner, 1992). The numbers over the arrow specifies the time needed. To know the relationships between activities what job precedes a particular job, what job immediately follows this job and what jobs can run concurrently have to be listed and the time required for the completion is estimated. Based on the chronological order in which they have to be completed, the following network diagram is constructed: From the above diagram we can understand the sequence of activities and their relative importance in the completion of the project. From the information provided we can tabulate and determine the critical path of the project. The Critical path is the sequence of activities which are crucial because delays to them will delay the completion of the project as a whole(Needham, 1997). The late finish and the late finish of the activities are calculated first. The early finish is the optimistic estimate of the completion time of the specific activity and the late finish is the pessimistic estimate of the duration of the activity. The slack time is the difference between the early finish and the late finish. In other words, the slack time denotes the time duration which can be delayed without delaying the entire project. But there are some activities which have the slack time zero, which means that these activities cannot be delayed. These activities are critical for the successful complet ion of the project because they cannot be delayed. The Appendix - 1 shows the calculation slack time of the activities. The calculation shows that the critical path consists of activities, A, D, H, I, J which are crucial for the completion of the project because they do not have any slack time. b) Normal distribution curves are very useful to analyze the frequency of data. When we construct a standard normal probability distribution table, the relationship between the mean of the distribution and the random variable is established. The formula used is: Z = x - / , Where, Z = number of standard deviations from x to the mean of this distribution X = value of the random variable with which we are concerned = mean of the distribution of this random variable = standard deviation of this distribution The value obtained from using the above mentioned formula is

Collaboration Project - Assignment Example I can still remember our conversations very late at night when we were supposed to be sleeping and our mom coming in to scold us for still being awake. We shared secrets that we swore we would never tell anyone and to this day as far as I know we have kept this promise. As we grew older I graduated from high school and started college while she was still in high school. We still remained close since my school was near to our neighborhood where I could commute. However, both of us became increasingly busy and we found ourselves spending less time communicating and interacting with each other. Before long, I was married and got my firstborn ten months after wedding date. My sister was still unmarried and living the single life going out after work whenever she wished. In retrospect, I think I was a little jealous of her carefree lifestyle because I faced responsibilities of taking care of my family. I quit my job in order to stay home and take care of my baby and my husband whom I love dearly. I would not have had it any other way, but I had a hard time adjusting to being at home every day. At this point in time we only saw each other about once every two to three weeks because although my family visited my mother with whom my sister still lived, she was hardly ever home when we were there. This is how it was for about fourteen years until she met and got married to her husband. She too, had a child within a year. Now that she was married and had a daughter that she stayed home to raise, she wanted us to spend time together but by then I was the one who was busy. I was working part-time and running all over town with my boys driving them to games or picking them up from after school activities. We talked through the phone but I always had to cut the conversation short to do something. My sister could not understand why I could shorten our conversation. According to her, now that she was at home, she could like us to spend time more time together but as for me, I had other more activities to attend. She grew resentful and it reached a point where she accused me of not being welcoming especially to her husband. Her accusation haunted very much and this made me angry and totally changed my attitude towards her. The unveiling events started to strain my relationship with my sister and we kept distance for a couple of years. I commenced this project in order to improve my relationship with my sister and try to restore the closeness we once had. I knew things would not change unless I put forth the effort to reconnect with my sister. I needed to let go of the past and let bygones be bygones. I needed to spend time listening to what she had to say as well as to spend quality time with her and her family. I found it necessary to start expressing myself clearly in order to eliminate and misunderstandings not only with my sister, but others with whom I interact. I also wanted to become less critical and more accepting of other people’s viewpoi nts and opinions. I intended to self-monitor to be certain that I was heading in the right direction toward achieving these goals. The hardest part of this project was getting started by reaching out to my sister. I didn’t want her to know she was part of a research project for grad school and I didn’t want her to become suspicious either. So, I initiated contact by emailing her and including a recipe I thought she might like to try. Goals and objectives Before the end of this collaboration, I had some objectives to
