21, 263 20, 298.6 21, 263 18,875
By interpolation we get, k = = 0.114 = 11.4%, k = 0.114 = ka = we ke + wd kd (1 – T) = 1/3 ke + 2/3(0.10)(1 – 0.46) ke = 0.234 = 23.40 percent. ke = Rf + βE (Rm – Rf)
or, 0.234 = 0.06 + βE [0.16 – 0.06]
Therefore, the equity beta of the company is given by βe = 1.74 Again, βe =βA [1 + D/E(1 – T)] or, 1.74 = βA [1 + 2(1 – 0.46)] βA = 0.837 Hence, the required asset beta of the company is = 0.83654 ≅ 0.84. < TOP >

The variance of the duration of the critical path has been obtained as 1.0959 weeks 2 and hence the standard deviation is 1.047 week. Therefore, the probability that the project may be completed by 30 weeks is given by: Probability (D 30 weeks) = N(z) where, z =

The NPVs of the projects starting one year hence have been calculated as follows: Project 6 7 8 9 10 NPV at the start Project 4.80 – 1.76 1.44 6.72 11.52 NPV (in Rs. crore) 4.29 – 1.57 1.29 6.00 10.29 Now, the outright rejection would be the projects with negative NPV and hence the projects to be considered for planning are 1,2,3,4,6,8,9,10. Now the formulation as per integer programming would be as follows: Objective function: Maximize: 15.4 X1 + 14.00 X2 + 2.76 X3 + 10.2 X4 + 4.29 X6 + 1.29 X8 + 6 X9 + 10.29 X10 The constraints are as follows: 22 X1 + 28 X2 + 46 X3 + 51 X4 + S1 = 100 ……………….Cash flow during first year 32 X6 + 48 X 8 + 56 X9 + 64 X10 + S2 = 125 + S1 × 1.07…..

Section C: Applied Theory 6.
Both soft as well as hard skills are necessary for successful project management – hard skills set the goals and procedures while soft skills make sure that people can meet those objectives. Soft skills: Visible leadership: The skill requires the project manager to set a vision and identify the action steps to achieve that vision. The project manager must inspire and lead his team members to achieve that vision. Flexibility: Project management is in many ways management of change. The ability to adapt and deal with situations and manage expectations during periods of change is therefore critical. Sound business judgment: Projects are conceived to meet business goals of the organization or/and that of the customer. Sound business acumen is therefore valuable. Decisions should be made after considering the business purposes and goals. Trustworthiness: Organizations are betting their future on their project managers to steer the projects to success. The success of the company is often connected to the success of the project. Hence creating trustworthy relationships is important for project managers. Exhibits several communication styles: Project managers must influence people to get action. The best way to get action is to communicate with each individual in his or her style. Being able to recognize a person’s communication style and adapt to it is an important skill. Hard skills: Every aspect of good project management processes and tools is a skill that project managers must acquire. Planning, estimating, scheduling, tracking, controlling are the functions that project managers should perform. The following are some of the key processes the project manager should master:
Project definition: Project managers must be able to define the project’s business objectives and goals, deliverables, assumptions and constraints and communicate this. Planning process: The project manager is expected to be an expert in scheduling and planning. Since planning depends on estimates, project managers should have a reasonable understanding of estimation processes, tools etc. Controlling process: The project manager must be able to define what each team member is expected to accomplish and to determine that it is accomplished. There are a multitude of management tasks that anyone heading up a project must accomplish. These tasks involve planning, tracking, and reporting the status of the work underway. These tasks are well documented and there is a large body of knowledge associated with performing these tasks effectively and efficiently. Almost all the books and training generated are for people leading a project deal with the “management” side of the job. The leadership tasks associated with heading up a project have not been given anywhere near as much attention. In fact it is the leadership qualities of the person heading up a project that more directly affect the successful outcome of a project rather than their management qualities. A project leader acts just like a business leader or CEO for the duration of the project. Business leaders understand the needs of the end customer and deliver those needs. They carefully nurture employees and maintain a skilled and motivated workforce. Business leaders work effectively with their board of directors providing information and leveraging their strengths for the benefit of the business. They show responsibility to their shareholders in reporting accurate information and offering outlook guidance. Similarly great project leaders focus on end customers, the work team, and internal stakeholders like the sales and marketing team, and shareholders in their projects like their executives. A great project leader, just like a CEO, focuses effort on the four key relationships: The customer relationship, the project team relationship, the sales and marketing relationship and the management relationship. So, it is the leadership qualities of the project manager that work as the key behind success in a project. < TOP >

There are four types of estimates, based on the inputs required and accuracy. The first type is called Order-ofmagnitude analysis. This method is used when the project is still in the conceptual phase. In this method, the cost of the project is estimated without using any engineering data. The estimate is rough and is arrived at using the past experience (relating to projects that may or may not be similar to the one on hand). The output of the order-ofmagnitude analysis may be ± 35 percent of the actual costs. Next is the approximate estimate. It is also made without detailed engineering data. This estimate is made by interpolating the expenditure on similar projects undertaken earlier. The expenditures made on the earlier projects are adjusted to reflect changes in price levels, etc. The adjustment is generally made by using rules of thumb, indexation methods, parametric curves and other methods which are simple to use unlike sophisticated or advanced techniques. The variation of the estimate made by approximation compared to actual expenses at the time of implementing the project is generally 15 percent on either side. Definitive estimates are more accurate and are based on detailed engineering data, well laid out plans, clear specifications, and reliable unit prices. Definitive estimates are also called detailed estimates. Their variation compared to the actual expenses is expected to be less than 5 percent. Finally, we have the method of estimation using estimation manuals. When this method is proposed to be used, estimation manuals have to be developed first, if they are not already available. The manuals contain standard costs for various tasks. The standard costs given in the manuals are determined taking into consideration all factors such as machine down time, lunch breaks, clean up time, set up time, etc. Estimates are developed for groups of similar tasks. These estimates are considered to be superior to the engineering standards, as all the factors are not accounted for in the engineering standards. When this method is used, up to 90 percent of the activities are estimated according to the standard costs given in the manual. The remaining 10 percent, which are generally nonrepetitive tasks and hence are not amenable to development of standards, are estimated separately. This leads us to the drawback of this method – only projects which contain to a significant extent activities that are common with other projects can be estimated using a manual. For projects containing unique activities in a major proportion, this method is not useful. Another drawback is the reliability of the estimates. It is very difficult not only to develop, but also to constantly update the manuals, without compromising on the quality of the estimate. < TOP >
