Establishing standard allowed minutes and sewing efficiency for the garment industry in Tanzania

Abstract

Purpose The garment factories focus on improving their production systems by involving innovative and advanced production methods and/or techniques to cope with fast-changing trends. Accordingly, this study aims to establish the standard allowed minutes (SAMs) and sewing efficiencies for Tanzania’s sewing industry, thus improving the production processes. Design/methodology/approach The research deployed a quantitative method. A stopwatch measured each operation for shirts and trousers to compute SAMs and efficiency. The shirt manufacturing processes involved 40 operations. Ten measurements were taken from different SL and LL industries operators for each operation. The trouser comprised 42 operations with 10 measurements taken from a different operator at the same garment factories for each operation. Findings SAMs for shirts at SL and LL factories were 29 and 31 min, respectively, while trousers were 30 and 34 min. The sewing efficiencies for shirts at both SL and LL factories were 83.98% and 81.93%, respectively. Similarly, the sewing efficiencies for trousers at both SL and LL factories were 81.25% and 80.95%, respectively. Research limitations/implications Since SAMs results are not established through literature rather a quantitative approach, the findings thus place crucial information for similar factories to benchmark from. Such information are crucial as factories could increase productivity and operational efficiency, reduce costs and non-value adding activities and estimate lead times. Notwithstanding the findings gathered, the study only established SAMs for two garments. Originality/value Although the garment industry has been developing over the years, this study was probably among the first studies in Tanzania that established SAMs. Theoretical underpinnings indicate that the factories use the experience to assemble garments, thus the need for this study.

A Mathematical Algorithm Approach for Estimating Water-Based Paint Requirements for a Given Wall

“…This includes wall measurements, the quantity of paint, and the wall applicator (brush or roller) issue. Achieving data reliability and viability provided the research's quality (Nchalala et al, 2022).…”

Assessing the digitalisation level of the Tanzanian apparel industry: Industry 4.0 perspectives

“…There are limited theoretical underpinnings regarding Industry 4.0 for several sectors, which is the case for the T&A industry. The most explored part of the T&A includes the sector’s general understanding, which seems to be the case due to the sector’s decline for a prolonged period (Taifa and Lushaju, 2020; Mwasubila et al , 2022; Nchalala et al , 2022). Thus, this study assesses the digitalisation level of the Tanzanian apparel industry through the Industry 4.0 viewpoints.…”
