Week 7_ Agbato Oluwabusayo__Determining the right deal in material purchase_Week 18 _SeeGod Meregini
Problem Recognition/Evaluation
A new material was to be bought by my purchasing company and I was told to work with the team in evaluating a good deal from a list of alternatives.
The root cause needed for this extra support was because of the following reasons:
· Previous purchases had been made based on incorrect analysis of cost cut deals in the offers.
· Previous purchases had higher prices gotten from hidden charges in the proposed offers
· Improper evaluation of previous vendor deals associated with the purchases materials resulted in more costly investments.
I needed to correctly evaluate the best economic alternative.
In this analysis the life of the materials would exceed one year hence the time value of money is a consideration.
Development of Feasible Alternatives/Solutions
After evaluations of different vendors and cut deals on their materials, three feasible alternatives is used based on cost that would be saved due to cut deals in the offers. The life of each of these materials was 7 years.
In carrying out this analysis, an assumption is that depreciation would not be calculated for each alternative.
Alternative 1-
Material 1
Alternative 2 –
Material 2
Alternative 3-
Material 3
Probable Outcomes of Alternatives / Solutions.
Stakeholders meetings within and between various departments including the vendors were held to determine the various savings included in the offers.
In this analysis evaluation is made on the potential cost savings in each bid offers.
Costs used are factored but have same equivalence with original for the purpose of showing the final result.
A breakdown is given below
Attributes | Material 1 | Material 2 | Material 3 |
Saved cost due to free services | $50 | $70 | $30 |
Free services | 2/year | 1/year | 3/year |
Interest on savings | 5% | 3% | 2% |
Selection Criteria in determining the solution
1. The highest cost deal would be selected
2. The most economical material based on cost savings from the deals offered would be selected.
Analysis and Comparison of the alternatives
In finding the present equivalent of the cost of future savings, a cash flow diagram would be used.
The formula below is used in determining the Present Equivalent of this future costs assuming the company is saving these costs (A) annually in a bank at different interest rates based on the provision of the banks.
P = A (P/A, i%, N) ......................................................................................Equation 1
Where:
P = Present Equivalent value
N = Number of compounding (interest) periods
A = Annual Equivalent value (occurs at end of periods 1 through N, inclusive.
Using N = 7 years for all alternatives

P = ?
I = 5%
A = $50
N (Cash flows periods) = 14 free services (2 free services /year * 7 years)
Using equation 1 and Discrete Compounding Tables,
P = $50(P/A, 5%, 14)
= $50 *9.8986
= $494.93
Alternative 2 – Material 2
Using similar cash flow diagram,
I = 3%
A = $70
N (Cash flows periods) = 7 free services (1 free service /year * 7 years)
Using equation 1 and Discrete Compounding Tables,
P = $70(P/A, 3%, 7)
= $70 *6.2303
= $436.1
Alternative 3- Material 3
Using similar cash flow diagram,
I = 2%
A = $30
N (Cash flows periods) = 21 free services (3 free services /year * 7 years)
Using equation 1 and Discrete Compounding Tables,
P = $30(P/A, 2%, 21)
= $30 *17.0112
= $510.336
Selection of Preferred Alternative
Based on the above quantitative analysis and criteria, I recommend ALTERNATIVE 3.
In addition, the fact that material 1 seems to have more cost savings that material 3, this does not mean it is a better deal.
The time value of money effect has resulted in Alternative 3 being chosen.
Performance Monitoring/Post Evaluation
This would be monitored by constantly evaluating
· The other risk factors not being analysed in the calculations like increased cost of maintenance to mention a few.
· The effect of depreciation on the market value of these materials after 7 years.

Interesting example, Agbato...... Perfectly acceptable, but a somewhat unique or different approach....
ReplyDeleteNormally, when procuring materials, the two main approaches are "low price" or "best value".
While your savings approach clearly falls under the "best value", normally when you apply the best value approach, we end up using some sort of multi-attribute method.
As an example, you calculated the savings, but what about the responsiveness or support? What about the warranties and guarantees? How likely is it the selected vendor is going to be in business over the long term?
Bottom line, invariably when we choose the best value over the lowest price, we apply some sort of multi-attribute decision model.
And thanks again to SeeGod for your work mentoring your colleagues. Very impressive leadership!!
