Earned Value Management (EVM) is an effective tool for project performance measurement that, if planned properly, can play a vital role for project success. EVM is based on scope, time and cost only while risks are not accounted for in planning process. Moreover, there are difficulties in acquiring real-time Actual Cost (AC) data for continuous monitoring and control, mainly due to the communication gap between engineers and accountants. Researchers have proposed different extensions of EVM for specific projects and in general. In order to apply the proposed EVM extensions, a real-time tourism facility project with sustainable energy & water resource at Kund Malir, Baluchistan is taken as a model. Costs, schedules, scope and risks are hypothetical in the model. Planned EVM is applied to the model with and without risks. Risk Costs and Scheduled Buffers are added in Planned Value (PV) calculations basing on probability-impact matrix factors. Furthermore, task level EVM models or Task-EVMs are integrated into Project-EVM or Master-EVM in order to minimize the problems being faced in acquiring real-time data. Industry specific application and research of EVM extensions proposed in this paper can be a good area for future research. Moreover, establishment of tourism facilities at unexplored or less explored areas of Sindh and Baluchistan can be another real-time research as well as a business project.

3. INTRODUCTION
 Earned Value Management (EVM) is an effective
tool for project performance measurement on
Time, Cost & Scope baselines
 If used properly, EVM can ensure project success
without major delays
 EVM models are mainly effective for Predictive Life
Cycle Projects
 Certain limitations are associated with use of EVM,
for which different extensions have been proposed
by various researchers

4. INTRODUCTION

 Risk Costs and Time Buffers are added in Planned
Value (PV) calculations based on probability-impact
factors for Risk
 In order to apply the proposed EVM extensions, a
hypothetical tourism facility project is taken as a
model

MODELS

15. TASK-EVMS INTO MASTER-EVM MODEL
 In order to get the real time data of AC and EV a
separate EVM for each task is to be planned and
maintained
 Task manager, with assistance of accounting/
stores professionals should keep his Task-EVM
updated
 Data for each Task-EVM is to be communicated to
Master-EVM, by a network or data link
 Periodicity of update of EVM is to be planned and
same is to be used for keeping every concerned
onboard of actual project performance

16. EXAMPLE
At time t, there are 3 parallel tasks A, B & C
Cumulative Calculations for Master-EVM
EVP = EVA + EVB + EVC
ACP = ACA + ACB + ACC + Ο
Ο is other associated costs, that does not add to the
Physical Work done in terms of cost

17. TASK & MASTER EVM
*Calculations were made from POM-QM software PERT cost-budgeting module

18. INCORPORATION OF RISK FACTORS
 Project Risk Management is a factor that assures a
project performance and completion as per
schedule
 PMs usually avoid maintaining a Risk Register
 A conflict situation may occur or project
performance may be affected badly, if risk
management is not done properly
 In order to avoid this situation, it is proposed that
risks are to be added to EVM planned value (PV)

19. INCORPORATION OF RISK FACTORS
0.36 here is Probability-Impact Factor

20. INCORPORATION OF RISK FACTORS
 All other Risks can be converted in terms of Cost
and Schedule
 In the model, only Cost & Schedule risks are
proposed for incorporation into EVM
 For calculation of risk values, Probability-Impact
factor (PI) is used in proposed EVM model

21. SCHEDULE RISKS
 It is proposed that for schedule risks, buffer times
are to be added to all tasks
 Calculations of buffer times are on the basis of PI
factors for proposed model
PIp: Probability-Impact factor (positive risks)
RVp : Risk Value (positive risks) RVp
PIn : Probability-Impact factor (negative risks)
RVn : Risk Value (negative risks)
TB: Time Buffer
Equation for Buffer Time:
TB = (PIn)*(RVn) – (PIp)*(RVp)

22. SCHEDULE RISKS - CALCULATIONS

based on PI factor is to be added to tasks

RVp : Risk Value (positive risks) RVp
PIn : Probability-Impact factor (negative risks)
RVn : Risk Value (negative risks)

29. IMPLICATIONS OF STUDY
 In practical approach, some risks cannot be quantified and are
based on previous experience and expert judgment of PM.
 There are Force Majeure Risks, like natural disasters, those
can only be dealt with by a project team’s efficiency,
experience, knowledge and resources.
 Efficiency in upkeep of Task EVMs by Task-Managers can
vary as per the priority of the task itself, associated works,
time and expertise in finance/management.
 Model of Vash-Rung tourism facility project is based on
hypothetical company, costs, schedules, team members and
potential for revenue in the project. It is not to be used for any
practical approaches, except for getting an idea for such
projects.

30. CONCLUSION
 Earned value management methodology takes into account
all three triple constraints that may delay a project or cost
extra expenditure.
 There always remain an element of error and difference
between on-ground project status and management level
documentation and tools like EVM. Proposed model for
dividing Master-EVM into task-EVMs will keep all stakeholders
onboard at any instant of time and real-time project
performance will be measured affectively.
 Project Risk Management is another major factor that assures
project performance and efficiency of team. Project Managers
generally avoid maintaining a risk register. Proposed model
for incorporating risks into EVM at planning level will give a
clear insight to all stakeholders. Moreover, during the project
life cycle, clear visibility of forthcoming risks will ensure early
risk responses.

31. FUTURE RESEARCHES
 Future researches can target reducing the gap between
theoretical/financial models and practice/physical status
of a Project.
 Identifying and quantifying risks is core competency of
any project management organization. Project Risk
Management integration with planning, execution and
monitoring & controlling of a project can be another area
of research.
 Hypothetical model of a tourism facility in Kund Malir
can be a full fledge research and business project, that
can be studied and implemented practically.
 Use of sustainable energy resources, capacity building
of local population and self-sufficiency in water
resources are few other areas that can be researched
for business as well as for poverty alleviation.
