| dc.description.abstract | Lean Six Sigma has become a
well-known tool to improve operational
excellence in manufacturing as well as
service organisations. Lean Six Sigma
generates a significant positive
contribution to an organisation’s
performance in improving processes by
reducing cycle time and waste in the
process. This study is focused on real
practical scenario of Hela Intimates (Pvt)
Ltd, Narammala which is having lengthier
time periods for the Acceptable Quality
Level (AQL) Audit procedure than the
Standard Operating Procedure time
periods. This is a qualitative and
quantitative research in nature. The main
research objective of this study is to
improve the process quality by reducing
the current cycle time using Lean Six Sigma
of the Acceptable Quality Level audit
process of the sample checking process at
Hela Clothing Ltd Narrmmala. Both
primary and secondary data are used to
reach the study objectives. Two thousand
three hundred and twenty-six AQL audits
in the month of June are considered for the
sample. Cluster sampling method under
Probability sampling method is used to
draw the sample and the direct observation
method is used to gather AQL audit cycle
time. In addition to that, three auditors are
interviewed in order to identify the waste
types in the AQL process. To analyse the
data, Lean Methodology and DMAIC
methodology which is used under Six
Sigma is used. Under this methodology
Process control chart, Non-value-added
activities calculations, descriptive statistics
and Perato chart are considered to analyse
the data. To analyse the interview data, the
contents and pattern matching method is
used. The results of the analysis revealed
that the present AQL Audit process is stable
and yet the process can be improved
further. Based on its AQL audit procedure,
cycle time is reduced to 35 minutes from 45
minutes and it is a 22% process
improvement from the current process by
using Lean Six Sigma methodology.
Therefore, it clearly evident that Lean Six
Sigma can be used as a process
improvement tool for apparel sector in
order to meet customers’ requirements. | en_US |
