objectives are achieved.
• Designed to inform, advise and enthuse teachers, students
and the general public about the BLOODHOUND SSC Project.
Above all “MAKE IT FUN” to learn.
• BLOODHOUND SSC STEM Ambassadors are all registered
STEMNET Ambassadors and DBS (CRB) “cleared”.
• Ambassador assignments include explaining the technology
behind BLOODHOUND SSC, the Design, Manufacturing,
Testing and Trials processes and progress leading up to the
Land Speed Record attempts.

BLOODHOUND SSC - Mission Statement
To create a national surge in
the popularity of Science,
Technology, Engineering and
Mathematics - (STEM) subjects

The Problem UK Faces:
100,000 STEM graduates are needed per
year from now until 2020.
Just 64,000 actually go into a STEM field.
We need to cover the shortfall or risk losing
our place as an engineering and innovation
leader in the world.

The Challenge
22nd January 2015

The Bloodhound Definition
The Bloodhound Programme Ltd is
an unreasonable
and disruptive aerospace
and education company
dedicated to innovation
and financed by sponsorship
and public donation revenues.

The man with a problem

The Hi-Q Sigma Challenge
To maximise the delivery schedule through
best utilisation of available resource and
identify opportunities to accelerate the
programme through scenario modelling using
a fully resourced schedule.
Resourcing would be people only, cost would
be considered separately.

4 Scenarios to be considered
1. South Africa date achievable with current
resources
2. Resource required to achieve South Africa
in 2014 weather window
3. Resource required to achieve South Africa
in 2015 weather window
4. Impact of a Media Jet Test 2013/14

Benefits ID
Benefits Identification
• Assist the building of a one team ethos
• Provide focus for the team on end delivery
• Demonstrate to each individual team member
how important their contribution will be.
• Provide assurance to existing sponsors of the
projects delivery timescales
• Provide the Bloodhound team with the ability to
demonstrate to new sponsors an achievable plan.

The Approach to Boodhound

Development of Schedule
• Car broken down to 15 Major Assemblies (PBS)
O1 Lower Chassis
O2 Monocoque
O3 Intake Duct
O4 Front Susp
O5 Rear Susp
O6 APU - Intake
O7 Internal Ducting/Pipework Connections
O8 Upper Chassis
O9 Airbrake Doors
O10 Front Structure
O11 Fin
O12 Fin Fairing
O13 Fin Strake
O14 Support Kit
O15 Assembly Jigs & Fixtures
• Containing 100 Sub Assemblies

Complex Design

Development of Schedule (WBS)
• Major & Sub assembly life cycles identified
1. Concept Design
2. Analysis
3. Detail Design
4. Manufacture
5. Assembly
6. Installation / Test

Complex Construction
The BLOODHOUND Build Team trial fit one of the carbon fibre
'cheek' pieces to the jet and rocket powered car. These run
from the Monocoque forward over the cooling ice tanks, front
subassembly and front suspension

Complex Multiple Power Plant
BLOODHOUND SSC engineers test fitting the
EJ 200 to the car’s chassis ready for
connection of all the engine’s services and
alignment checks, the engine weighs 991 Kg

Complex Multiple Power Plant Pt 2
• BLOODHOUND's rocket partner, Nammo, successfully fired the new hybrid
rocket. This firing lasted for a predefined 16 seconds, producing a
maximum thrust of 30 kN (or 3 tonnes). The temperature in the rocket
reached 2,500°C and 1,400°C in the plume.
• The rocket started instantly after ignition and the firing was terminated in
a controlled manner by closing the main oxidiser valve.
• BLOODHOUND will use one rocket for high speed testing 2015 and a
cluster of three rockets to reach 1,000mph in 2016.

Development of Schedule
• Predecessor and successor identified for each
sub assembly and linked in schedule
• For each sub assembly activity an estimated
duration and existing available resource
allocated.
• Major Assemblies given priority order for design,
manufacture & assembly.
• Major Assemblies for Media Jet Test identified
and prioritised

Initial Logic and Critical Path Analysis
• Sanity check of activity scheduling to ensure logic correct and 1st
critical path identified to be front structure.
• Resource levelling applied with existing team allocated, identified
delivery to S Africa Q1 2017.

INITIAL CRITICAL PATH CHECK - LOGIC LINKED, CURRENT RESOURCE APPLIED, LEVELLED

Scenario 1 – Date with Current Resources
Refining the Schedule
• To ensure the resource levelling did not influence activity
scheduling, priorities were applied to all sub assemblies.
• The full schedule was then reviewed by the team to identify
potential conflicts. This addressed a significant number of
improvements both in dependencies and resource allocation.
• The activity durations were revisited by the team to drive out any
over pessimistic estimates and whilst some durations were
revised down they did not lie on the critical path and failed to
reduce the overall duration.
• The resource graphs were analysed to ensure maximum
utilisation of resource and some smoothing of resource was
achieved through reprioritisation of activities.

Scenario 1 – Date with Current Resources
• The output from further resource levelling resulted in a delivery
to S Africa end Q3 2016
Jul-13 Mar-17
SCEN 1 - CURRENT RESOURCE APPLIED, LEVELLED

Scenario 2 - South Africa 2014
• To understand the level of resource required to achieve a SA 2014
date the ‘maximum availability’ of current resources was
increased to 1000%
• The schedule was then levelled to provide a date in Q4
2014…..HOWEVER…..
Jul-13 Mar-17
SCEN 2 – 2014, UNCONSTRAINED
RESOURCE

This scenario proved unachievable due to the requirement for :
• 75 additional designers immediately
• 31 additional stress engineers immediately
• 5 additional assembly engineers
• Unlimited availability of parallel manufacturing facilities

• The achievement of a 2014 date, even provided with
unlimited funds and the immediate recruitment of a huge
amount of additional resource, is impossible due to:
– The number of resources physically able to gain access to the
assembly
– The loss of valuable existing resource utilisation whilst
providing oversight and mentoring to new resource, i.e.
current resources become full time managers.

Scenario 3 ‘What Ifs’

WHAT IF 1 – TWO ADDITIONAL ASSEMBLY ENGINEERS ADDED
WHAT IF 2 – THIRD ADDITIONAL ASSEMBLY ENGINEER ADDED
BASELINE – CURRENT RESOURCE APPLIED, LEVELLED
8 Months Saved

Commence Desert Running - TARGET
No further saving
WHAT IF 3 – ONE ADDITIONAL DESIGN ENGINEER ADDED 3 Months Saved
This is the point at which the Critical Path is no longer driven by
resource constraints, but by task durations

Scenario 3 – South Africa 2015
The team then concentrated on developing a REALISTIC and
ACHIEVEABLE schedule based upon the recruitment of a limited
number of additional resources, to be allocated to critical activities
This resulted in a date in Q2 2015, a 15 month saving
compared to Scenario 1

Designer Support Kit Design Aug-13 Feb-15 7
Assembly Fin Assembly Feb-14 Sep-14 7

Scenario 3 - Critical Path

• Total average cost per month of additional
resource would be £30k, peaking at £65k
• However, the project completing 15 Months
earlier results in a saving of £380k*
• Mechanisms for increasing resource -
– Recruit additional premium rate (£65/hr) resources
(included in Scenario 3 schedule)

• Prerequisite for bringing in premium resource
– Uncapped overtime at an enhanced rate for current
resources (not included in schedule – contingency for
risk mitigation)
– Estimated monthly cost £20k

Scenario 4 – Media Jet Test
Jul-13 Mar-17
SCEN 3 - ADDITIONAL RESOURCE APPLIED, LEVELLED
SCEN 4 – MEDIA JET TEST

Scenario 4 – Media Jet Test
• Initial planning process indicates that a media Jet Test could
occur during Q4 2014
• This will inevitably have an adverse impact on the SA date,
this is estimated at 10 weeks
• Further detailed planning is required to fully understand the
schedule for the Jet Test and the remaining activities post Jet
Test

The inevitable over optimism

Task Dependant Critical Path
Next Steps;
Re-assess logic and durations of critical activities
Investigate ‘outsourcing’ some of this work
Decide whether Aux Intake Cassette Assembly is required

Progress Metrics

Bloodhound Laid Out

The lessons
• Invariably most plans are optimistic.
• Over optimism is inherent in most people and difficult to
overcome
• Even the best constructed plans can only be realised by people
and there is your biggest problem!
• Understanding the personalities of key personnel is essential
• You will never capture all the activities required for the ultimate
schedule.
• Be prepared for the schedule to increase in size and complexity as
it matures before you can simplify and reduce working complexity
• The analysis of data and its presentation needs to be tailored to
your customer.
• Some like lots and the decision making is paralysed
• Others like to keep it simple and make effective decisions
• Know and understand your customer, help them to help
themselves

Maintaining a Realistic View
• Optimistic durations
• Changes to timings
• Believe in the plan

Summary
• Produced a detailed schedule
• Greater control of the project
• Inform and align the team
• Clearly present the information
• Ensure it remains up to date

Are the benefits being Realised?
• Assist the building of a one team ethos – There are
visible signs in both behaviours, project knowledge and
respect of others contribution which demonstrate greater
cohesion and ownership of the project across the whole
team
• Provide focus for the team on end delivery – Whilst
some pessimism remains among a few the vast majority
are showing real commitment to achieving the 2015 South
Africa milestone
• Demonstrate to each individual team member how
important their contribution will be – The bloodhound
technical centre rest room is plastered with the latest
delivery schedules and are a constant source of information
used by the team

Are the benefits being Realised?
• Provide assurance to existing sponsors of the
projects delivery timescales – The Castrol PR lady and
the world cup
• Provide the Bloodhound team with the ability to
demonstrate to new sponsors an achievable plan -
Jaguar now a major sponsor
