Transcript Undulator Production Schedule

In a project, we live or die by the schedule.




After we’re “baselined” it is our plan for what we
will accomplish and when, and it is the
government’s plan for funding us.
If we’re late, the cost goes up. We pay more for
people to work longer than planned, plus the
value of the money gets escalated.
Being late means maybe having to give up or
postpone some things. DOE probably can’t find
more money. They have a schedule too.
Too late and the project may be cancelled.

To Succeed: Plan Well. Stick to the Plan.




The requirements must be clearly defined.
The responsibilities and interfaces must be
clearly defined.
Use talented and experienced designers.
Use experienced reviewers.
There’s no glory in reinventing the wheel, so
use what we can from other people and
projects. There are enough challenges as it is
without solving old problems over again.
Do not make cosmetic changes late in the game.

The Exception

The exception is if we are building something
that we know won’t work.

It’s better to be a little late on something that
works than on time with something that
doesn’t.

We’re here to make sure we all know
and agree on what we’re doing….




The prototype was constructed and tested, and
many of the drawings are close to final.
At this stage, changes will cost time and money,
proportional to the degree of the modifications.
If the requirements have changed significantly
since we began, or if they were misunderstood
and the present system won’t work, changes
must be made.
If there is a disagreement based on personal
preference and both methods will work, consider
whether it is important enough to potentially
result in loss of something else down the road.

Acquisition Strategy



The undulators were designed and prototyped
by APS, based on the combined experience of
many people over many years. This decreased
the technical and schedule risk to LCLS.
Our design and assembly procedures will be
furnished to the assembly vendors; any changes
by the vendors will require our approval.
As a direct result of the US funding system, we
will procure some critical long-lead parts early
and furnish them to the assembly vendors.

Long Lead Procurements




Long lead procurements are those undulator
components that are expected to have long
delivery times.
Orders are to be placed as soon as there is
money next FY in order to maintain the
schedule. We assume that there will be money
by November 1st 2004.
Large and/or complex procurements take
months to prepare, and require significant effort
from procurement and project staff.
High-value procurements need DOE signoff.

And then…

After the long lead items are awarded, there is a
lag time, during which the vendors procure their
materials, make the objects, and secondary
vendors are machining parts.

Then it’s time to award the undulator assembly
work. The schedule is very tight on that, and we
really cannot afford to delay without putting the
schedule at risk.

Decisions

In these 2 days, we need to make decisions
about the critical issues so we can proceed.

We can leave room for options, but it must be
clear to us what options are likely. Flexibility is
expensive.
