Project Selection Methods

Project selection methods provide a systematic approach for selecting the project with maximum value to the organization. We need to select a proper selection method based on organizational requirements and the nature of the business. Otherwise improper projects will lead to take wrong decisions.


We can use following methods to analyze potential projects and select most suitable project for the organization.

(1) Present Value (PV)
(2) Net Present Value (NPV)
(3) Internal Rate of Return (IRR)
(4)Payback Period
(5)Benefit/Cost Ratio
(6) Economic Value Added (EVA)
 
Lets we analyze above methods further.

Present Value

PV indicates the present value of future cash flow. Projects having higher PV will be better. Present value of a future cash flow is discounted to reflect the time value of money. We can use following equation for Present value calculation purpose.

           PV = FV / (1+i)*n 

Example 01
Assume that there have two investment opportunities as follows, 

Project 01  - You will receive Rs: 90000 after 5 years. 
Project 02  - You will receive Rs: 130000 after 10 years.
  (The interest rate is 10%) 

PV of Project 01 =         PV = 90000/(1+.1)*5
                                                = RS: 55883

PV of Project 02 =          PV = 130000/(1+.1)*10
                                                =  RS: 50121  
  Project 01 is the most suitable project because it provide highest present value than project 02.


 Net Present Value
 
NPV is the difference between cash inflow and out flow considering present value of both cash inflow and outflow. Again project with higher NPV is better. NPV should be positive for the project to be selected; negative NPV indicates negative cash flow.

Example 02
DD company is considering to purchase a machine. There have 2 alternatives and their cost and cash flows as follows,


Machine A                                                 Machine B                                          
Cost = RS: 12000                                    Cost = RS:8000
Cash flows (RS)                                       Cash flows (RS)                                    
Year 1 = 5000                                          Year 1 = 4000
Year 2 = 3000                                          Year 2 = 300
Year 3 = 3500                                          Year 3 = 500
Year 4 = 4500                                          Year 4 = 5000
  
Machine 01
Year       Cash flow             DF@ 10%            PV
0              (12000)             1               (12000)
1               5000               0.909           4545
2               3000               0.826           2478
3               3500               0.751           2629
4               4500               0.683           3074
 
NPV =   RS:  726 


Machine 02
Year       Cash flow      DF@ 10%        PV
 0              (8000)             1               (8000)
 1               4000             0.909           3636
 2               300               0.826           278
 3               500               0.751           376
 4               5000             0.683           3415 
                                              
 NPV =   RS:  (295)  

Project 01 is suitable for invest as it has Positive NPV. If both project had positive values, we should select the project with highest positive value. 
 
Internal rate of return

IRR is the rate at which the present value of investments is equal to the present value of return on all investments made. If there are multiple projects in consideration, project with higher IRR is better option. 
 
 IRR = r1   +    NPVa                  (r2 – r1)
                  (NPVa – NPVb )


 Example 03 -
 Lets we consider above example,

Machine A                                                Machine B
Cost = RS: 12000                                    Cost = RS:8000
Cash flows (RS)                                       Cash flows (RS
Year 1 = 5000                                          Year 1 = 4000
Year 2 = 3000                                          Year 2 = 300
Year 3 = 3500                                          Year 3 = 500
Year 4 = 4500                                          Year 4 = 5000
NPV =  726  (i = 10%)                           NPV =  (656)  (i = 12%)     


 IRR =   0.1 + 726/ (726- (-656) * (0.12 – 0.1 )
IRR = 11.05%


 Payback Period
 
Payback period is the time required to recover the cost of investment for the project. Payback period alone doesn’t consider time value of money or rate of return on the project. If other parameters are same, project with minimum payback period is better.

Following information are regarding two machines, DD company considering to buy which gives lowest payback period. Decide which machine the financial manager should buy?

Machine A                                                Machine B                                                

Cost = RS: 12000                                    Cost = RS:8000
Cash flows (RS)                                       Cash flows (RS)
Year 1 = 5000                                          Year 1 = 4000
Year 2 = 3000                                          Year 2 = 1000
Year 3 = 4000                                          Year 3 = 500
Year 4 = 4500                                          Year 4 = 2500    



Machine A                     Cumulative cash Flow
Cost = (12000 )                     (12000)                    
Cash flows (RS
Year 1 = 5000                  (7000)                      
Year 2 = 3000                  (4000)                       
Year 3 = 4000                     0                    
Year 4 = 4500                   4500                     
 
•     Payback period is 3 years.





 
Machine B                 Cumulative Cash flows (RS)                      
Cost = (8000)                        (8000)
Cash flows (RS)                                    
Year 1 = 4000                        (4000)
Year 2 = 1000                        (3000)
Year 3 = 500                          (2500)
Year 4 = 2500                           0 
 
Payback period is 4 years.     







Benefit/cost Ratio
 
BCR is the ratio of benefit  in terms of money to monetary cost of the project. If budget is not a constraint, higher the BCR better the project. All cost and benefits should be in terms of present value while comparing.
            
  BCR = Benefit / Cost
 
EX --
DD company is considering to buy new plant which costs RS: 55000 and the estimated revenue for the year was RS:500000, Calculate BCR.
 
BCR = Benefit/cost
        = 500000 / 55000
        = 9.09
 
It means company will receive RS:9.09 for every RS:01 which company invested.

What is systems

What is a System?

Ackoff defined system as “A System is a set of two or more elements that satisfies the following conditions;

Ø  The behavior of each element has an effect on the behavior of the whole.

Ø  The behavior of the elements and their effect on the whole are interdependent

Ø  However subgroups of elements are formed, each has an effect on the behavior of the whole and none has an independent effect on it”

So a system is a collection of interacting and interdependent component parts form a complex/ intricate whole. These systems are can be considered as a set of rules that governs structure and/or behavior also. There have several elements of a system,

1-      Boundary – A boundary separates a system from its environment. This means it separate the elements as which should be inside and outside.

2-      Environment – Environment means part of the world with which the system can interact. So always systems and environment are interrelated.

3-      Observable Interactions – This means how the system interacts with its environment.

4-      Subsystems- A system can be decomposing into small parts and each of these parts also a system. These small parts are called as subsystems. These subsystems are totally interdependent.

5-      Control Mechanism- Control mechanism means how the behavior of the system is regulated to allow it to endure. Often there have a natural mechanism of control.

6-      Emergent Properties – There may have two types of properties, (1) Properties that holds of a system, but not of the parts, and (2) Properties that cannot be predicted from studying the parts.

In the practical situation there have several types of systems and the examples for these situations can be identified as follows,

Type of the system	Examples
Natural systems	Ecosystem, Weather, Water cycle, The human body
Abstract systems	Set of mathematical equations, Computer programs
Symbol systems	Languages, Street signs
Designed systems	Cars, Planes, Buildings, Telephones
Human activity systems	Business, Organization, Markets
Information Systems	Banking system, Database
Control systems	Autopilots
