Abstract
Problem The aviation industry is a branch with extremely high quality
requirements on spare parts and belonging documents. These
documents, which assure that a part complies with authority
requirements, are scanned and electronically saved in the stock
receipt at Lufthansa Technik Logistik GmbH in Hamburg. The
quality level of scanned documents is to investigate and shall
provide useful information for the development of quality
improvement actions in this thesis.
Method A combination of a qualitative and a quantitative approach has
been chosen for this thesis. This is called triangulation. The
working methodology “Six Sigma DMAIC methodology”, which
contains the five phases define, measure, analyse, improve and

Problem The aviation industry is a branch with extremely high quality

quality level of scanned documents is to investigate and shall
provide useful information for the development of quality
improvement actions in this thesis.
Method A combination of a qualitative and a quantitative approach has
been chosen for this thesis. This is called triangulation. The
working methodology “Six Sigma DMAIC methodology”, which
contains the five phases define, measure, analyse, improve and
control, was used as a roadmap for a structured working
procedure. Random test and comparative studies were chosen as
techniques for data collection. The random test was performed on
scanned documents and the comparative studies in form of
benchmarking at an external company and internal at Lufthansa
Technik Logistik in Frankfurt. A Failure Mode and Effect
Analysis (FMEA) was used to objectively use the result of the
random test. This also enabled to take the severity of the effects
and the possibility of failure detection before processes or
customers are affected in consideration. The most critical failures
could thereby be identified.
Conclusions The random test revealed several failure types and also showed
that the average quality level is higher at Lufthansa Technik
Logistik in Frankfurt than in Hamburg. The FMEA and the random
test indicated that the solving of the following failures were to
prioritise:
· Black fields on “Airway bill”.
· Askewly scanned “Authorised release certificate” where data
is missing.
· “Authorized release certificate” is not automatically
recognised.
Development of a Quality Assurance System in the Stock Receipt
· Black lines along scanned documents.
The following solving suggestions have been developed to solve
the most critical quality problems:
· Procure a scanner, which is able to scan “Airway bills”.
· Procure a scanner and software, which can scan and process
documents larger than A4.
· Always scan “Certificates” with a solution of 300 dpi.
· Configure the software at all working stations so that the
image always appears on the monitor after a document has
been scanned.
· Work out co-worker guidelines, which describe how and when
to clean the document scanner and how to avoid askew
scanning.
· Work out a control document, which verifies performed
scanner cleaning and maintenance.
· Inform the co-workers about the importance of OCR-readable
”Authorised release certificates”.
· Perform an additional random test on not automatically
recognised ”Authorised release certificates” to identify the
main reasons for a non-successful automatic recognition.
· Increase the quality controls on “Airway bills” and certificates
until satisfying solutions have been implemented.
· Consider centralising the document scanning and to let expert
co-workers perform the document scanning with one or more
high performance scanners.
New random test shall be performed in the future to verify the
success of implemented actions. (Less)
