On a Customer MeetingOur team has already completed the microwave design for 13 markets and we are ready to order the equipment.

We don’t have so much time.. Our leased line partner will be no longer exist next year due to bankruptcy. We have to move all sites from leased line to microwave network.The quotation for the equipment must be in my desk 2 months for now... Then we must start the roll out for those 6000 links next 4 months.

BruceAccount Manager

RobertCustomer

Well that is tough... But let me discuss with my team…And I will get back to you soon…

On an Internal Sales Meeting

The customer asked about the price quotation for those 6k link on 2 months for now...

SwatiSolution Manager

AlexProject Manager

I will make the shopping list for all imported parts including the price based on our solution…

I will ask the engineering team to provide the Bill of Materials based on the design and solution…

BruceAccount Manager Please don’t try to make any mistakes

on the calculation, every single error will have effect on this "multi millions dollar" project. Our company policy can only tolerate 0.1% errors maximum.

On an Internal Project MeetingGreat job for completing the design on time… Anyway we have to provide the BOM as soon as we can. The deadline will be 2 months from now.

AlexProject Manager

Well… That would be challenging for us. Currently I have no more resources for engineer other than Adi and Tatiana. Others engineers are already booked for VN Project.I doubt we can complete it within the time frame.

Gentlemen, this is the solution that we offer to our customer so please use this product based on our agreement with them.

SwatiSolution Manager

I can compile the whole design from the market engineer and I will match it with the product that you proposed.However this is will take 4 months to finish it with 2 engineers only.

MarkEngineering Manager

AdiEngineering Lead

On an Internal Engineering Meeting

I can’t believe it. We have to complete the BOM within 2 months for 6000 links with 0.1% error maximum.Adi, help me to understand how we calculate the resources for this…?

Based on my experience each site will take 15 minutes. If only me and Tatiana we can complete it within 4 months the fastest. We need 2 more engineers to meet the deadline.

MarkEngineering Manager

AdiEngineering Lead

TatianaDesign Engineer

Based on direction from our top management team we cannot add more engineers until the end of the year. We can bring some contractors however they will cost $70 per hour!

Moreover.. If we bring more people for this project , it will create more human errors, inconsistencies and need good coordination between us. I think that would be inefficient way and I believe the error will be more than 5%.

On an Internal Engineering Meeting

Alright I hear you.. So what is our plan..? Do you have any idea for this?

Currently I am very busy with VN project so I appreciate any ideas to solve this.

I have idea to automate this work, however we need a programmer..

MarkEngineering Manager

AdiEngineering Lead

TatianaDesign Engineer

I don’t think we have resource for programmer at the moment.

You may try to ask HR department maybe they have an intern with programming skills…

That’s a great idea… Thank you Tatiana..

On an Internal Meeting with HR

Our project currently demand a programmer to help us building the automation.

You come on the perfect time… We just hire a intern who has specialty in programming… However please don’t expect her so much on telecom technology, she need someone who can guide her to do the job…

MarkEngineering Manager

My engineer can help her. That wouldn’t be a problem.I appreciate for your cooperation.

I have experience with SQL, .NET, and C#.

DanielaHR Manager

That’s would be great… Welcome to our team..And good luck.

Problems

• Speed and accuracy requirement to build the BOM.– Speed: 2x faster than normal.– Accuracy: 0.1% maximum error tolerance.

• Lack of resources.– Hiring new engineer will take 2-3 months.– Hiring contractor will be costly for engineering

department.

Feedback for Future Project• The algorithm to generate the BOM cannot be re-used for different

projects or customer however the system provide customization for the programmer.

• GUI for the user is still not user-friendly, better design and flow on the GUI are required for future project.

• We almost achieved the maximum error required by sales manager (0.5% instead of 0.1%). This is due to some incorrect data inside the input files. We need better system to validate the input files more precisely and put more effort to socialized the standard template to the market engineer.

Summary

• Automation successfully solve the engineering team problems by generating BOM thousands time faster than manual work.

• Automation can minimize the error during BOM generation up to 0.5%.

• Automation reduce the demand for contractor that will cost ~ $ 44k more for this project.

Question..?

Thank You!
