Exercise I Event Log

Exercise I Event Log

Following are the messages that document the exercise as it progressed between 8/9 through 8/12. I took the liberty of altering some text (mostly omissions) for the sake of clarity and brevity. Note that the systems' clock were not synchronized--messages from hpark@wash1 do have the correct time. Also message from me (hpark@wash1) should be read as if they were from Frank. I was actually at sparki logged remotely into wash1, sending messages for Frank, who was sitting next to me.

Date: Tue, 9 Aug 94 09:55:00 PDT From: wimber@aic.lockheed.com (Lane S. Wimberley) To: acaps@sunrise.stanford.edu Subject: Just a note... Frank has used the "Question/Comments" facility to ask for clarification from Sandia. I think I may have presented some ambiguity by placing the "Questions/Comments" button on Frank's home page (people outside the firewall cannot see this page - it is specially designed to accomodate the activities that take place in the shop) That button is connected to the acaps email reflecter. The way it should probably work is that Frank could press a button on the rough quote request to send a message directly to the customer. This is an enhancement for the future. In the mean-time, the current method should suffice for the demo (Frank can use the general "Questions/Comments" button to send messages to Sandia)

The retrieval of the design data (the GIF sketch) was done by me, and not done automatically. In the future, it could be done automatically (I didn't have time to implement anything for the exercise) but there are a few problems: it would probably only work if the customer has *anonymous* FTP capability (otherwise, they should mail or FAX the information) and there are a few issues of synchronicity. But I think it's doable for the next go-round (hopefully not for a coulpe of weeks!)

Rather, it marks the end of the E-commerce part of the exercise. Sandia should contact the shop either directly (Ie phone) or via email (to schalk@sparki.msd.lmsc.lockheed.com) to submit a purchase order for this exercise. In the future, the purchase order will work like the other request forms.

Sandia was unable to view the drawing and pin-to-pin list that the shop generated. I have corrected the pages so that the information is available from the final quote. This reflects a bug that I will have to fix. There was no component list generated by the shop, so that is not available from the final quote page. Let me know if there are any problems.

Date: Tue, 9 Aug 94 15:22:00 PDT From: schalk@sparki.lmsc.lockheed.com (Frank Schalk) To: acaps@cdr.stanford.edu Subject: |Production Log Status: Activity has stopped here at Lockheed (Operators checking out for the day). To recap - All CMT modules functioned properly to generate the Wirematic Code, Cablescan Codes, and Quote. Although primitive (ie. from a PS2 system Floppy, to a IBM386 Floppy to an IBM-XT Floppy and communication to the Wirematic HP 1000 system) the Wirematic code was downloaded, verified, optimized and added to out Production database. The layout plot was good (5 min); Pinning the board was easy (10 min); Laying wire was uneventful (7 min); and the finish (tape,tie,ID,braid and jacket) was straight forward (25 min). We should be able to finish the harness by tomorrow.

Date: Tue, 9 Aug 94 17:38:13 PDT From: wimber@aic.lockheed.com (Lane S. Wimberley) To: hisup@sunrise.stanford.edu Subject: Re: [schalk@sparki.lmsc.lockheed.com (Frank Schalk) : Production LOG ] > sparki's clock is off. Lane, can you fix it from where you are? No. Only a sys admin ("root") can do this. In general, this will almost always be a problem. People are in different time zones, and different computers' clocks will always differ. (although there has been some discussion of "unerversal digital timekeeping" and standard synchronization protocols) But I suppose it's probably a good idea to at least get sparki (and hitchhiker) within a few minutes of the local time!

Two hours on this work..and we are about 1/3rd complete. The potting cure time is eight hours... The harness could be ready to ship first hours Friday.

Date: Wed, 10 Aug 1994 15:06:12 -0700 From: Hisup Park To: acaps@cdr.stanford.edu Subject: error encountered A clarification is helpful here regarding the mishap Frank reported: One of the concessions the team made for this exercise was a decision to leave out the normal shipping and material handling of cable components. In real life, one can envision three viable ways to deal with the shipping and material handling needs: 1) the shop keeps a full inventory of all components needed for a class of harnesses; 2) resort to a network of agile component suppliers that will deliver the parts as soon as a PO is initiated by the customer -- ala PartNet; and 3) the customer provides the components with the order. For ACAPS exercise I, we resorted to method 3, and the parts were delivered to the cable shop prior to our exercise. What happened is that the customer delivered a spool of wire of wrong gauge (AWG 20 rather than AWG 22). Frank assumed that he received the correct material--it is difficult to distinguish between 20 and 22 gauge wire spools by visual inspection. And the production process continued until the last few steps of soldering the wires to the pins--at which point the operator discovered that the wires were too big for the pins. The cable was essentially built at this point, and the harness had to be scrapped. It took Frank 40 minutes to find a spool of correct wire, and by 1:30 the harness was ready to be rebuilt. The overall cost of this mishap -- an extra day and the cost of the scrapped wires. This ... points to a very interesting element of ACAPS: the importance of rapid recovery from human error to the viability of the ACAPS approach. ... In real life (and in exercises), mistakes like this happens all the time. So imagine what would have happened if this mistake took place between a cable user and an external supplier (minus the technology we applied in ACAPS): this would effectively have doubled whatever it takes to order and build that harness manually. Several weeks of delay in a prototype schedule could kill a project. This is precisely the kind of scenario that would prevent companies like Lockheed and Sandia from producing prototype cables externally, and why each major company maintains internal cable shop(s)....

Date: Thu, 11 Aug 94 12:29:51 PDT From: schalk@sparki.lmsc.lockheed.com (Frank Schalk) To: hisup@cdr.stanford.edu Subject: Re: status Hisup, We're having great difficulty with the solder connections due in part to the "used" connector (which has to be cleaned first). Presently we have to finish the P8 connector (eight more wires) then wire the P1 connector for the adapter (Cablescan) and finally P1 of the harness. Completing this - the harness is tested for continuity (Cablescan) then potted. It's shaping up into a nice looking little showpiece, I think. My best guess now is that we won't finish until tomorrow.

The main reason is that Frank and I would like to hold on to the cable until we can get some photo and video footages of the cable for various documents. (We will also reconstruct some of the production steps for the video we are developing for ARPA.) I would like to schedule a meeting to recap our exercise as early as possible. Please inform me of your schedule so I can set a time. I thank all the participants for their contribution to ACAPS. I especially thank Lane Wimberly, Larry Harada (AIC), and Rob Frost for their programming efforts that made this exercise possible. I thank Robert Hillare for undertaking the preparations and activities at Sandia, and Frank Schalk for overseeing the production steps. Congradulations to everyone for a successful exercise. Hisup.
