Problem Recognition,
Definition and Evaluation
Sancai Heavy Industries is our most disaster
contractor. We build 5 vessels there. 3
vessels already delivered and all late more than 50 days. The 2 vessels remain
should be delivered on 15th Novemeber 2012 and 15th
December 2012. Here the last progress of these vessels :
Table 1 : Last Progress of MT. Singomenggolo
& MT. Sembada
Based on contract, we may terminate the
vessel if more than 80 days from contract delivery date the vessel do not
finish yet. The shipyard promise the vessel may be delivered no more than 80
days from the contract delivery date. But we are not sure
Problem Statement
What
will we do for the 2 remain vessels? Terminate or continue?
2.
Develop of the Feasible Alternatives
a.
Continue the contract.
On the day 80th, we may choose the option to terminate or continue
the contract
b.
Terminate the
contract. Only can be terminated on the day 80th from the contract
delivery date.
3.
Develop the outcomes
for each alternative
a.
Continue the
contract. If the vessel delivered no more than 80 days, the shipyard pay
penalty based on the delay days. If the late delivery days more than 80 days,
the shipyard only pay penalty max 80 days
b.
Terminate the
contract. Only can be terminated in the day 80th from the contract
delivery date. If we do not make decision until the 90th day, it
means we accept to continue the contract. So we only have 10 days to make
decision. The problem is we can’t make sure the BOD may decide no more than 10
days. Because for the vessel price more than 20,000,000 US$ is need 5 Director and
CEO approved. If we terminate the contract, we may take the refund guarantee
from the shipyard financier. The refund guarantee value is same to how many
payment we already paid plus LIBOR in this year
4.
Selection of the
acceptable criteria.
The parameter we use :
a.
Schedule Performance
Index (SPI) = BCWP/BCWS = Actual progress / Progress Plan
b.
Predicted Delivery
Date using EVM =
Date Equal BCWP + [(Contract Delivery Date – Date
Equal BCWP)/SPI]
Figure 1 : Calculate
Predicted Delivery Date
5.
Analysis and
comparison of the alternatives
Based on the simulation, we calculate the SPI and
Predicted Delivery Date as below :
Table 2 : Predicted
Delivery Date
6.
Select the preferred alternative
Based on the calculation, the shipyard is
able to delivery no more than 80 days from contract delivery date. The
preferred alternative is continue the contract and gives penalty to the
shipyard based on the delay days
7.
Performance Monitoring & Post Evaluation of Result
The progress of these vessels will be monitor every week.
Using the progress report we may control the SPI and Predicted Delivery Date
per week to make sure the vessels will be delivered not more than 80 days from
contract delivery date

AWESOME posting, Pak Indra!!! Loved it!!!
ReplyDeleteGreat to see you actually using EVM in a real life application to help you in making a tough decision. This is EXACTLY what this course is all about.
My only comments are you really shouldn't be using only one curve. A contractor will never hit the early dates. Without a late date curve, you will never be able to judge when the contractor is really headed for trouble in enough time to head it off.
Explained another way, the time to terminate the contract should have been made way earlier than ~75-80% complete. Once you get past that percent complete, rarely does it make any sense to cancel the contract. That should have been done no later than ~25% to 35% elapsed time. Research (by Bill Ibbs et al) has shown that if you don't identify your project is in trouble AND take corrective action to fix it, then you will NEVER be able to recover. Which means you would need to modify the terms and conditions in your contract to allow you to cancel somewhere between Day 20 and Day 28.
But I really like your case study and will be curious to see exactly what day they do finish on..... See how accurate your projection was...
