DESI Management Strategy • The project is dependent on the delivery of work packages by institutions and personnel whose funding we do not directly control. This presents a management challenge. • We have chosen suppliers of major subsystems with extensive experience with similar projects • Collaborator tasks are organized into well-defined, compact portions of the WBS owned by the collaborator personnel • We have been holding numerous ad hoc as well as regular weekly meetings with collaborator personnel — Weekly status, schedule and costing meetings with level 2 managers — Weekly Engineering meeting — Regular technical meetings with the optics group, the focal plate development effort, Spectrograph development, fibre activity, and Mayall interface • We have had excellent cooperation from our foreign and university collaborators in receiving schedule and cost input, BOE data, risk registry input, etc. , as well as in the development of conceptual and preliminary hardware designs H. Heetderks 09/09/2014 DESI CD-1 Review BO 4. 1 4
Managing DESI (con’t) • A very important management activity is to maintain full awareness of technical, schedule, and cost status so that emerging problems can be identified and dealt with before they become major issues — Develop and track a detailed schedule — Well understood Level 2 and 3 Milestones — Maintain continuous dialog with Level 2 managers — Track costs closely (e. g. EVMS) — Track, mitigate, and retire risks • Finally, we will insure that technical and safety related processes are done by assiduously following carefully developed written procedures H.

DESI Holds Contingency in 3 Areas • Cost Contingency -- We hold back a portion of our available funding to account for errors in the cost estimation process ($8, 289 K) , and the added cost of unexpected events as calculated from the Risk Registry ($2, 706 K) • Schedule Contingency -- We have included 14 months of schedule float between the early finish delivery of the DESI instrument equipment and our baseline CD-4 (as developed from the Risk Registry), as well as additional float applied to selected subsystems, (e. g. optics) • Scope Contingency -- We have specified threshold and objective KPP’s so as to insure that minimum science requirements will be met with high probability even in the event of loss of all foreign funding, but that allow enhanced science in the more probable case of near to full foreign support H. Heetderks 09/09/2014 DESI CD-1 Review BO 4. 1 34
Cost Contingency Analysis I • Total cost contingency is comprised of two components — Cost Estimate Contingency • Accounts for added cost due to incorrect cost estimates, i. e. imprecision of estimates put into BOE sheets — Risk Contingency • Accounts for added cost due to risk from untoward events • Developed from Monte Carlo analysis on risk registry • Cost estimate contingency determination — Estimated material and labor costs from Level 2 managers are entered into the resource loaded schedule developed in MS Project — Level 2 managers generate Basis of Estimate (BOE) sheets at WBS level 3 which document the process used to develop costs — Each level 3 material and labor cost is classified according to one of a list of maturity classifications (See DESI-0314) — Standard contingency values are assigned for each level 3 material and labor cost based on the chosen maturity classification — The BOE results are summarized in DESI-0314 where the Cost Estimate Contingency is calculated 35 H.

Summary of Labor Contingency Rules from DESI-0314 • L 1 – Complete: 0% contingency on items that have been completed or funded by an R&D account or “named positions”, eg. Project Manager, System Engineer, etc • L 2 – Level of Effort: 20% contingency, for example the task of overseeing the fabrication and testing of an electronics component. • L 3 – Established Procedure: 20‐ 30% contingency for a very similar task that has been done before and has documented time durations; . • L 4 – Defined Procedure: 25‐ 40% contingency for a task that is conventional, well defined and tends to be repeatable with good confidence but can expect small fluctuations; for example, testing of production electronics components (most boards take the same unit time, a few take longer • L 5 – Similar Procedure: 30‐ 50% contingency for a task that is not yet completely defined, but is analogous to past activities; for example, a fabrication activity similar to, but not exactly like, items fabricated for other activities • L 6 – Expert Opinion: 50‐ 70% contingency for a task that is not yet well defined. H. Heetderks 09/09/2014 DESI CD-1 Review BO 4. 1 36
Summary of Materials Contingency Rules from DESI-0314 • M 1 – Complete or R&D: 0% contingency on items that have been completed, or for acquisitions funded by an R&D account. • M 2 – Multiple Quotes/Travel: 10‐ 15% contingency on items that have already been purchased within the past year or for which there is a recent (within 1 year) catalog price or firm quote and for with more than one potential vendor. • M 3 – Single Vendor Quote: 15‐ 25% contingency on items that have been purchased at least once within the past two years or for which there is a recent catalog price or firm quote but for which there is only one likely vendor • M 4 – Preliminary Design: 25‐ 40% contingency on: items that can be readily estimated from a reasonably detailed but not completed design; items adapted from existing designs but with minor modifications, produced within the previous two years, with documented costs. A recent vendor survey based on a preliminary design belongs here. • M 5 – Conceptual Design: 40‐ 60% contingency on: items with a detailed conceptual level of design; items adapted from existing designs but with extensive modifications • M 6 – Novel Fabrication: 50‐ 70% contingency on items with unproven fabrication yields or e. g. a special‐order item or a single preferred vendor). • M 7 – Pre-conceptual Design: 70‐ 100% contingency on items that do not yet have a detailed conceptual design.

Required Float vs Confidence H. Heetderks 09/09/2014 DESI CD-1 Review BO 4. 1 40
Scope Contingency • Reduce number of spectrographs manufactured • Number of positioners is also proportionally reduced • Can be done anytime, but after CD-3 with proportionate diminishing returns • Can meet threshold KPP’s with as few as 6 spectrographs • Can be reversed if funding situation improves • Can recover up to $5 M of cost and 6 months of schedule — Maximum cost savings requires decision to be made by CD-3 H.

Major Procurements We have completed a design well past conceptual level which has allowed us to fully understand our major procurements • • • • • Corrector Glass Corrector lens grinding and polishing Corrector lens AR coating Cage, Barrel, and Ring fabrication Hexapod manufacture Focal plate structure manufacture (petals and ring) Fibre view camera and lens assembly Guider CCD detectors Robotic fibre positioners Optical Fibre Spectrograph camera assemblies Spectrograph bench and integration Spectrograph cryostat mechanical fabrication Spectrograph pulse tube coolers Spectrograph CCD detectors Instrument Control System computer equipment Science data disk storage H. Heetderks 09/09/2014 DESI CD-1 Review BO 4. 1 52
Major Procurements • Corrector glass boule procurement — High priority long lead -- Contracts for C 1, C 2, C 3, C 4, in place using foundation funds — Required to initiate the critical path corrector fabrication • Corrector lens grinding and polishing — High priority long lead -- Contract for C 2, C 3 in place; we are in negotiations with the apparent awardee on C 1, C 4 — Occurs coincident with boule procurement to allow development of fixturing for grind & polish • Corrector lens AR coating — In the corrector critical path — Lengthy (3 -4 mo) process; may have to be re-done • Cage, Barrel, and Ring fabrication — Needed to complete corrector assembly and alignment — Requires careful selection of vendors -- similar parts on DES had to be remade to meet tolerance specifications H. Heetderks 09/09/2014 DESI CD-1 Review BO 4. 1 53
Major Procurements • Hexapod manufacture — This was a 2 year procurement on DES because of time needed for vendor to complete the design — Time can be saved if we build an identical unit with same vendor • Focal plate structure manufacture (petals and ring) (foreign inkind procurement) — This has been the subject of substantial R&D related to choice of material, and identification of vendors who can meet tolerances — Prototype manufacture complete • Fibre view camera and lens assembly — A fully operational prototype of this system has been developed and extensively tested — A production unit will be procured to enable software upgrades to be developed and tested without impacting science data collection • Guider CCD detectors — This is a room temperature operation device with sufficiently good specifications to provide tracking for telescope — Cost of the detectors is a substantial fraction of the total guider cost H. Heetderks 09/09/2014 DESI CD-1 Review BO 4. 1 54
Major Procurements • Robotic fibre positioners (DOE with substantial university and foreign contribution) — Will cost $4 M — DOE with substantial in-kind contribution from U. Mich, UAM/CSIC (Spain), and EPFL (Switzerland) • Optical Fibre (foreign in-kind procurement) — This market is dominated by a single supplier (Polymicro) — DESI throughput is optimized by using a custom diameter (107 microns) • Spectrograph camera assemblies — PO for Prototype cameras is in place at vendor — Company is a strong candidate for the production cameras • Spectrograph bench and integration — In final negotiations with vendor to perform development of prototype H.

Heetderks 09/09/2014 Prob. DESI CD-1 Review BO 4. 1 Mitigation/Response 58
Risk: DOE Funding Stretched Out • A 3 month continuing resolution has been assumed for each FY • If the proposed funding profile is delayed beyond this, we will make up the shortfall by the use of contingency • If this is insufficient, we will reduce scope towards the threshold KPP’s H. Heetderks 09/09/2014 DESI CD-1 Review BO 4. 1
Risk: Loss of Foreign Funding • DESI project objective KPPs can be reached only if foreign Collaboration funding as currently understood comes to pass • The DESI IPT is closely monitoring and being responsive to the needs of these relationships to maximize these foreign contributions • The DESI project will ask to have the foreign MOU’s agreed to at the highest governmental level possible • If this funding does not develop, the DESI project has established threshold KPPs that would still be achievable • Additionally, cost contingency could replace some portion of foreign contributions • If this is not adequate we will reduce cost and hence scope by reducing the number of spectrographs and positioners built H. Heetderks 09/09/2014 DESI CD-1 Review BO 4. 1
Risk: Polishing Takes Longer • Vendors from whom we have quotes express high confidence in their schedule estimates but experience on other projects suggests a 6 to 12 month slip is not unlikely • This risk is being managed by careful procurement, including development of detailed specifications, rigorous source selection, and close performance management • We have further mitigated this risk by including additional schedule float in the corrector lens fabrication over and above that applied to the overall project • Delay of lens delivery will not materially affect other WBS elements H. Heetderks 09/09/2014 DESI CD-1 Review BO 4. 1
Risk: Barrel alignment needs large CMM • Risk arises because current plan for aligning lens cells in barrel involves use of a Coordinate Measuring Machine (CMM) at FNAL which was used on the DES barrel alignment and was thought to be too small • This risk will be retired by either 1) Procuring a larger CMM (~$600 K) at FNAL using capital equipment funds, or 2) Subcontracting with a machine shop which has a CMM of the needed size H. Heetderks 09/09/2014 DESI CD-1 Review BO 4. 1
Risk: Inadequate production rate for positioner fibre assembly • Risk arises because Durham University does not have sufficient laboratory technician staff to support needed rate of polishing of fibres to be installed into positioners • This risk will be retired by either 1) Hiring needed staff and additional polishing equipment, or 2) Using a cleaving technique which avoids the polishing operation — Testing and evaluation of the cleaving process is underway H. Heetderks 09/09/2014 DESI CD-1 Review BO 4. 1
Risk: Grating Efficiency/Wavefront does not meet specification • Our backup grating vendor has stated that they cannot meet DESI requirements on the grating • Primary vendor can meet requirements, but other higher priority jobs may take presidence • We may have to accept lower throughput (~ 2% hit), or accommodate a schedule slip H. Heetderks 09/09/2014 DESI CD-1 Review BO 4. 1
Risk: Damage to Lens • As with the corrector lens polishing risk, this risk is being managed by careful procurement, including development of detailed specifications, rigorous source selection, and close performance management • We will mitigate this risk by employing carefully developed procedures and QA practice to the lens handling activities, review of vendor procedures, and minimizing the handling and transportation of the optical components • We have allowed sufficient float in the lens manufacturing schedule to accommodate the re-manufacture of one lens provided there are not additional schedule delays H.
