Planning & Control van Research & Development projecten
Mission Impossible? Ir Hans Minnee
2
Wat gaan we doen vandaag (en voortaan ?)
Stellingen Wat is project planning & control 3 Cases R&D projecten Wat leren we ervan Wat doe je ermee in je eigen project
3
Stellingen The beauty of NOT planning is……
that failure comes as a total surprise, instead of being preceeded by weeks of worrying and agony!
4
Stellingen R & D is een ontdekkingsreis: Je weet niet waar je uitkomt
Je weet niet hoe lang het duurt Het heeft dus geen zin om dat te plannen!
5
Stellingen Failure to Plan = Plan to Fail! Beter een vaag plan
dan helemaal geen plan
6
Wat is Planning van een project
Een meetbaar resultaat van het project doel (Scope) omschrijven en vertalen & opdelen naar concrete activiteiten (Work Breakdown Structure) en + leveringen (Deliverables) die naar het doel leiden. Logische activiteiten volgorde in WBS aangeven en in de tijd zetten (van laatste naar eerste) en in een ”netwerk” (parallele en serieele verbanden) Aan activiteiten kosten en uren toewijzen (budget) Een team formeren met juiste capaciteiten (kwalitatief + kwantitatief) en koppelen aan activiteiten (Organisation Breakdown Structure) Afspraken maken / bevestigen met klant, team en leveranciers + overige belanghebbenden Identificeer risico´s en heb daarvoor alternatieven
7
Wat is Control van een project
Regelmatig activiteiten meten qua voortgang zowel op tijd en op budget (naast performance) Vraag je als team af: gaan we zo de eindstreep halen qua performance, tijd en geld en wat zijn de bottlenecks (Kritieke Pad) in netwerk en de risico’s Analyseer oorzaak van vertraging en budgetoverschrijding ….en leer er van! Stuur bij door andere oplossingen en nieuwe / betere afspraken te maken / bevestigen met klant, team en leveranciers + overige belanghebbenden.

Fokker Thermoplastics R&D, Technology status, 1998
Press-forming: in production status Resistance Welding: proven on a demonstrator part, ready for industrialization Consolidation technology: R&D phase Next step forward: full assembly on a series application customer: British Aerospace, A /600
12
Results of the first meeting with Airbus (AUK / BAe)
potential for a business case: Airbus / British Aerospace design Fokker production technology Ten Cate material good chemistry between people involved new team leader at Airbus, willing to pick up a challenge agreement on a phased study with: a 1:1 prototype calculations to support a business case
13
Business case J-nose thermosets -$ thermoplastics -w $ aluminum weight
14
QUESTION What should AUK bear in mind when considering a thermoplastic J-Nose rather than the prior (proven) metal version?
15
Weight savings (20%) offset against:
ANSWER: Weight savings (20%) offset against: costs per component basis and for installation, on a per-aircraft basis investments in design modifications, material specs, co-operation with Fokker risks: what if it doesn’t work or Fokker is late?
16
PHASING Demonstrate feasibility of application / Prototyping Submit and negotiate proposal Full scale development
17
Development of the Business Case: Feasibility Study
AUK wants to reduce risks: agrees with Fokker that a demonstrator should be developed and built Is prepared to pay for a demonstrator (Phase 2 of feasibility study)
18
The prototype: 1.5 metres in length simplified prismatic cross-section
Skin sheet, ‘consolidated’ in an oven mould 1.5 metres in length simplified prismatic cross-section with prototype tools Ribs, welded onto skin sheet mould Pressed ribs and stiffeners mould
19
Problem definition: Delivery time
It is mid January. Phase 2 will not be complete till the end of May. Main reason: duration of tooling AUK ‘NEED DATE’ PROTO JAN FEB MAR APR MAY PHASE 1 PHASE 2: demonstrator GO/NO-GO tools production For AUK, however, the go/no-go decision point is at the end of April, 1 month earlier. The proto absolutely has to be in Filton by then QUESTION: How to solve this?
20
Answer: Analyse Critical Path => tooling and process development
Start on proto tools at own expense, a month before finalisation of phase 1 Set up an exact planning and check/act continuously Make all resources available, including a full free hand for the best specialist within the company Have a dedicated Team in 1 place
21
A340-600 ‘J-nose’ prototype (1998)
AUK: ‘sounds like metal, must be good’ operators: repair friendly
22
PHASING Demonstrate feasibility of application / Prototyping Submit and negotiate proposal Full scale development
23
Fokker Proposal to AUK : basic input
Technical description: Design & fabrication concept Calculation of costs: Recurring costs (RC): per product, with learning effect and inflation Non-recurring costs (NRC): design, tools (moulds), work preparation Completion time Planning: Best guess, based on previous projects
24
QUESTION: What should Fokker Management take into account in the quotation to AUK?
25
ANSWER: part of a PLAN! what is the ‘cost vs. price’? (price = cost + profit) what total price is the customer (AUK) prepared to pay? do we have the money to amortize the non-recurring costs & capital investments? can government provide assistance (development and financing credit)? over how many aircraft to we do that (business case analysis)? what risks does Fokker incur and what bottlenecks are there and what are the solutions? how familiar are we with the technology and how much development is needed? do we have the specialist people needed or can we train new people in time? what is the likelihood of quality problems and too late delivery (penalties and loss of reputation)? is our materials partner (TCAC) reliable regarding their share?
26
Risks, J-nose development
tight schedule new customer new technology data Airbus/BAe not on time, loads late
27
Why then the J-nose development?
Entry ticket to A380 => much bigger volume
28
PHASING Demonstrate feasibility of application / Prototyping Submit and negotiate proposal Full scale development
29
Plan=>Do=>Check: Problem: material does not satisfy requirements
During the design phase (the end of 1998) after Ten Cate tests: the glass/PPS composite material proved not to satisfy the strength requirements after prolonged exposure to moisture and extremes of temperatures These test were never concluded in the pre-study phase, owing to a number of different circumstances
30
How to cope with a great project setback?
QUESTION: How to cope with a great project setback?
31
ANSWER: Plan=>Do=>Check=>ACT: Crisis management!
Inform client quickly and discuss route forward: creates commitment and confidence to work together in finding a solution Form crisis team made up of one’s own experts + client + externals (including TU’s) analysis cause / effect brainstorm solutions + selection actions definition / allocation 2x /week progress monitoring/co-ordination with parties: Keep own management well informed
32
Problem: material does not satisfy requirements
Technical solution: Quickly weigh up different alternatives: A different fibre: the more costly but stronger S-glass instead of E-glass. Not feasible in the short time that was available Different ‘sizing’ (type of bonding agent) between the fibre and the resin. Improvements to strength proved feasible but drawbacks in processability later emerged

Case 2 : DUT 2004 Race Car Design & Build & Race
Ultra light weight design principle Highest effort in body design & production and Engine tuning, OK Plan=>Do=>Check: Machined parts designed and ordered too late! No capacity anymore at suppliers. Threat: Too late assembly, no time to test Question: What should we do now???
49
ANSWER: Plan=>Do=>Check=>ACT: Crisis management!
Analyse the Critical Path => Turning & Milling of relative simple alu parts Form crisis team of own + externals (Fokker coaches) brainstorm solutions + selection: BUY Lathe and Milling machine and train DUT team members! actions definition / allocation frequent progress monitoring RESULT : car ready just in time for tests and race!

CVO Technology development project ‘thermoplastic control surfaces’ 2003 - 2009
Design studies: dimensioning, certification, materials&processes Skins: co-consolidation New material Assembly: welding Spars: co-consolidation Ribs: press forming
53
Problem erupted: first product not OK
Late design because of late customer inputs Bad Welds Contour not OK Plan=>Do=>Check: Root Cause : Tooling too weak, long lead time Threat: Too late assembly, & delivery Question: What should we do now???
54
ANSWER: Plan=>Do=>Check=>ACT: IMPROVISE and BRUTE FORCE
Analyse the Critical Path => Tooling needs to be upgraded Form crisis team brainstorm solutions + selection: Re-inforce tooling by temporary stiffeners switch to 24/7 production with frequent checks actions definition / allocation frequent progress monitoring RESULT : First shipsets just in time for static tests and first flight!

Wat leren we hier van Elk project kan niet zonder een projectplan JUIST voor R&D omdat dat nieuw is: Breek je SCOPE op in meetbare DELIVERABLES Zet duidelijk je MILESTONES neer, met speling op het eind Plan je ACTIVITEITEN qua logica en samen met Murphy: zorg ook voor plan B voor elk risico Gebruik ervaring voor inschatting van duur en haalbaarheid Doe het samen (Visual Plan) en check het Kritieke Pad (er is er altijd 1!) Control hoort er altijd bij; PLAN>DO>CHECK>ACT (elke week / dag), en wees voorbereid op Crisis Management Blijf er voor gaan als TEAM, help elkaar en schakel!
