A generic framework of testing and development efficiency has
been presented, covering two distinct methods, namely the four
lever approach and the system optimisation approach.
• The 4 lever approach has been applied multiple times and has been
proven to provide significant gains in test field effectiveness.
• System optimisation – Achieving the optimal balance between the
engineering test requirement and testing capability is a powerful

A generic framework of testing and development efficiency has
been presented, covering two distinct methods, namely the four
lever approach and the system optimisation approach.
• The 4 lever approach has been applied multiple times and has been
proven to provide significant gains in test field effectiveness.
• System optimisation – Achieving the optimal balance between the
engineering test requirement and testing capability is a powerful
concept which can be used to improve test field effectiveness.
• A circular work flow phenomenon has been presented which originates
from a mismatch between engineering requirements and test
capabilities. This mismatch is often explored in an iterative timeconsuming
way. System optimisation is proposed to be a suitable
remedy.
• The full potential of investment in facility cannot be realised
without commensurate attention to development process, organisational
change, training and communication between test and
engineering.
• The philosophies presented can be used to justify expenditure on
test facility upgrades with a specifically targeted benefit to the
development process. Visa mindre

The paper documents some of the findings from a joint JLR and AVL project which was conducted at the JLR Gaydon test facility in the UK. A testing and development efficiency concept is presented and test data quality is identified as a key factor. In support of this methods are proposed to correctly measure and set targets for data quality with high confidence. An illustrative example is presented involving a Diesel passenger car calibration process which requires response surface models (RSMs)… Visa mer

The paper documents some of the findings from a joint JLR and AVL project which was conducted at the JLR Gaydon test facility in the UK. A testing and development efficiency concept is presented and test data quality is identified as a key factor. In support of this methods are proposed to correctly measure and set targets for data quality with high confidence. An illustrative example is presented involving a Diesel passenger car calibration process which requires response surface models (RSMs) of key engine measured quantities e.g. engine-out emissions and fuel consumption. Methods are proposed that attempt to quantify the relationships between RSM statistical model quality metrics, test data variability measures and design of experiment
(DOE) formulation. The methods are tested using simulated and real test data. Visa mindre

This report is investigating at how “improving customer performance” is used as a business model innovation approach throughout different industries. As a methodology, case studies and their structured evaluation for commonalities and differences were chosen.

This report is investigating at how “improving customer performance” is used as a business model innovation approach throughout different industries. As a methodology, case studies and their structured evaluation for commonalities and differences were chosen. Typically “improving customer performance” is established as a new business model which replaces the old ways of doing business. As it is providing better perceived value for the customer it always leads to differentiation of a certain supplier. This is always ONE of the strategic goals. Others can be market entry for a supplier accompanied by shaping a new business or situations driven by the customer, e.g. to outsource a part of the value chain in order to increase profitability or flexibility. Often stronger customer retention is a feature of the new model. A complete survey including conclusions for different markets is provided. Visa mindre

Ford Powertrain Test & Development together with AVL implemented
a 12 month Efficiency Pilot study. Three test rooms were converted
to high efficiency capability yielding an approximately doubling
in test productivity. This was achieved through a combination of
change in Process, Tools and Attitude / Skills of People.

Ford Powertrain Test & Development together with AVL implemented
a 12 month Efficiency Pilot study. Three test rooms were converted
to high efficiency capability yielding an approximately doubling
in test productivity. This was achieved through a combination of
change in Process, Tools and Attitude / Skills of People.
Following problem definition and a needs assessment study three
development tasks were selected:
(1) Gasoline Calibration mapping.
(2) Diesel Emissions calibration.
(3) Gasoline Thermodynamic development.
A limited infrastructure update was completed to achieve required
test room standards and control and automation tools were then
installed. Quick change pallet capability was introduced into two
rooms together with a palletisation preparation area.
The largest opportunity for increased utilization was to harness time
when the test room was previously shut down. Increased utilization
was achieved by running during unattended periods under automated
control. Pallet exchange capability for engine running-to-running with full
parameterization update is consistently within the 20 minutes target
and ex- change in under 7 minutes proven.
The pilot directly supported Calibration program delivery for two
Powertrain applications – a gasoline Boosted Direct injection with
VVT unit and a diesel HPCR unit with VNT application. With enablers in place utilization doubled. Data Quality measure of
data points First Time through substantially improved with less than
6% repeats required. This paper highlights a cultural change that been has been started
within Powertrain testing and development activities to meet current
and future Powertrain development program requirements both
increasing the speed and flexibility in testing and hence program
delivery. Visa mindre

In my career as Ph.D. Student, Univ.Doz., Asst. Prof. and Senior Scientist I published 150+ Papers and Book Chapters - mainly on science and technology of organic semiconductors
