Garment Measurement Standard

The World’s Most Accurate Standard Time Measurement System For The Garment Industry 


What Is GMS

GMS (Garment Measurement Standard) was established in 2010 as a consulting project to establish a computerised work measurement system that is:

1. Accurate
2. Reliable
3. Universally Named
4. Methods Description
5. Work Done Sequence
6. Easy-To-Learn
7. Fast-To-Apply
8. Based on MTM-2

The project consultant, C.H. Wong is a distinguished Certified MTM Instructor and Expert with more than 25 years’ experience and he has established all the required Motion Patterns of the sewing industry for manual, mechanical, man-machine and automatic template sewing lines.

The GMS system was found to be the most significant high speed motion pattern estimating system for the Sewing Industry and is able to set accurate and reliable standard at a faster speed than GSD.

In 1984, C.H. Wong met Jim Mercer, the founder of Methods Workshop and signed an agreement for the distribution of GAD (General Assembly Data) and got familiarized with GSD at that time. After being certified as an MTM Instructor, he set to work in developing a higher application system for the Sewing Industry which has evolved considerably since the invention of GSD.


How Is GMS Developed

GMS is based on industry standard system of MTM-2 which is the database of GMS. MTM-2 was chosen because it fundamentally meets the eight demands of International MTM Directorate in achieving a very high level of consistency for standard time development.

As the motion pattern of sewing operators’ exhibit some variation in distance as well as the motion type, it is therefore an acceptable practice to adopt MTM-2 as the most desirable database for the establishment of higher standard data for Garment Sewing operations.


GMS Special Classified Motion Pattern Data

GMS was developed from actual study of garment sewing operators’ motion patterns. After disallowing for unnecessary motions of the operators and based on Standard Work Methods, the following motion patterns were established:

a) Pick and Place Fabric
b) Pick and Place Part / Tool
c) Pick and Match Small Parts
d) Pick and Match Fabric
e) Place Part
f) Foot Match Assembly
g) Adjust Parts
h) Shape Forming
i) Machine Operation
j) Pick and Place Template
k) Open and Close Template
l) Tool Handling
m) Remove Material n) Get and Aside
o) Get Part and Lift
p) Get Part and Regrasp
q) Get Part and Press Light
r) Get Part and Press Hard
s) Get Part and Slide
t) Get Part and Push/Pull
u) Get Part and Pass to the Other Hand
v) Draw with Pencil
w) Eye Action Check
x) Weight Force Application
y) Body Motion Turn and Bend
z) Walk Steps

Selection of Motion Patterns

These are determined by:
a) Type of Motion Pattern
b) Motion Pattern Break Point
c) Method of Assembly
d) Degree of Difficulty
e) Distance
f) Weight Factor


What Operational Methods Are Covered By GMS

The GMS system can be customised for unique in-house process and this can be specially developed for the special application and can be included on the GMS Datacard. Almost all the Garment Industry’s operational methods are covered by GMS:

a) Washing of Garment
b) Drying of Garment
c) Mini-Pack to Packaging
d) Final Pack to Carton
e) Carton Box Making
f) Needle Detection
g) Inspection and Thread Trimming
h) Ironing
i) Sewing of Panels – Small
j) Sleeve, Collars
k) Front to Back Panels – Singlets, Shirts, Coats, etc.
l) Sub-assembly – Cuffs, Sleeves, Pockets, etc.
m) Botton Holes Making
n) Labelling and Hole Punching
o) Zip Sewing
p) Counting and Stamping
q) Fabric Cutting (Auto and Manual)
r) Bundling
s) Setup for Auto-Cutting
t) Embroidery Operations
u) Fabric Relaxation
v) Material Handling, etc.
