SARASWATI, D.; SARI, E.  and  SEKARWARDHANI, G.. Development of a sustainable lean competitive strategy in a water pump company. S. Afr. J. Ind. Eng. [online]. 2024, vol.35, n.1, pp.152-167. ISSN 2224-7890.  http://dx.doi.org/10.7166/35-1-2910.

The manufacturing industry is currently experiencing a shift towards sustainability-driven practices and principles. Company X is one of those who want to improve their competitiveness in the manufacturing industry by implementing sustainability. However, this company experiences obstacles in its production process because production targets still need to be achieved owing to product defects that average 8.97%. This study used the sustainable lean manufacturing approach to help the company to achieve more competitive goals by reducing waste and pollution and creating more efficient production processes. The tools used in this research were process activity mapping (PAM), sustainable value stream mapping (SVSM), and the sustainability index (SI). Based on calculations with sustainability indicators, the company's SI results amounted to 183%. The proposed improvements were given to improve the company's efficiency and to reduce its SI. After repairs had been made, the SI value was reduced to 118%. With the improvement in that value, production efficiency has also improved: the process cycle efficiency (PCE) value has become 90.49%, which means that the company's production process has become more efficient.
