Title: A Review of Six Sigma and the Shared Relationship with Knowledge Management (KM) Discipline Authors: U-Dominic, Chukwuebuka Martinjoe; Godwin, Harold Chukwuemeka Abstract: Six Sigma and KM are two distinct disciplines that support each other, and subsequently, create a strong foundation for learning when used concurrently in an organizational context. Although, six sigma objectives tend towards process improvement while KM objective is all about the right flow of information and knowledge, however, there is a very powerful intersection and synergy between the two disciplines that promote process performance. The reported cases on failed six sigma projects have been on the rise, due to organization's inability to create a learning environment, fit enough to engage employee's capabilities in solving quality related problems such that knowledge of the process is retained and not lost after the six sigma project. Recently, very few organizations are now acquainting themselves with these two notable improvement strategies in quest of becoming more ambidextrous to positively frame process problem as an opportunity for improvement. This paper explored the potentials of these two disciplines, by taking a narrative review both from the academic and in the practitioner's point of view to bring to limelight their level of synergy and appreciation both in scholarly and in organizational domain. This study has underscored the level of awareness and poor utilization of these two disciplines in improving organizational performance among manufacturing firms. The paper further expounds on the need for organizations to focus in building an organic knowledge structure that will favourably sustain newly-stabilized processes, and also suggest for more integration of both disciplines since there is no standardized model(s) of integration of six sigma-DMAIC and KM to widely capture knowledge on other integration tactics Description: Scholarly work

Title: Application of Lean and Quality Management in AB Brewery Authors: Ujam, Chinedu James; Godwin, Harold Chukwuemeka Abstract: The Introduction of new product brands into the Nigerian market as a strategy to attract new customers has had breweries’ struggling to meet product demands with the available capacity. In order to increase production output and satisfy customers, operational efficiency is a topmost priority. Production analysis reveals that the brewery is underutilizing her available production capacity due to high machine breakdown, external and planned downtimes coupled with huge amount of waste generation within the system. These led to a comprehensive analysis of production problems of line 1 for 13 weeks, with the application of Correlation Analysis, Pareto Analysis, quality Analysis and Toyota’s problem solving framework. The result of correlation analysis of running time against production volume was 0.8, which is a positive trend and an indication of worthiness of production volume positive relationship with running time, hence the need to reduce downtime to increase running time. The result of Pareto Analysis shows that the External downtime was 46% of total downtime, while Empty Bottle Inspector (EBI) and Washer were 12% and 10% respectively. The Un-packer has the lowest downtime of 2%. In Quality Analysis, quality of raw material input affect machine operation and increase waste generation. In Filler, when bad crowner hooked at the rectifier, production automatically stopped, delay of 2 minutes will result in high reject of filled bottles to avoid foreign gas introduction to the beer. Stoppage at Filler and Labeler mostly affect production flow. 50% of total wastes were generated at the Filler and Washer while Labeler recorded high reworks and rejects. Description: Scholarly work

Title: Comprehensive Analysis of Thatch Grass from Southeastern Nigeria for Sustainable Particleboard Production Authors: Godwin, Harold Chukwuemeka; Chukwu, Hillary Ejike Abstract: This study presents an investigation into the viability of thatch grass as a sustainable raw material for particleboard production. The transition from traditional thatch to modern roofing materials has resulted in environmental challenges, including increased wildfire risks. The key objectives of the study was to investigate the suitability of hyparrhenia grass for sustainable particleboard production. Proximate analysis, following ASTM standards, was employed to assess moisture, ash, volatile matter, and fixed carbon content. Density was determined using a Pycnometer. The study encompassed samples from five Southeastern Nigerian states, employing triplicate analyses for each parameter. The study contributes to regional industrial development and aligns with sustainable development goals; while emphasizing ecological and economic benefits. The methodology involves proximate analysis and density assessment, employing standardized protocols for moisture, ash, volatile matter, and fixed carbon content determination. Moisture content falls within ASTM E871-82(2019) standards, validating suitability for particleboard production. Ash content ranges from 2.238% to 2.837%, indicating potential compatibility with particleboard production standards. Volatile matter content (75.565% to 77.761%) aligns with biomass material standards, supporting suitability. Fixed carbon content falls within the range of 16.338% to 18.305%, meeting ASTM D3172-13 (2021)e1 standards. Bulk density ranges from 0.820 g/ml to 0.848 g/ml, complying with ASTM E873-82 (2019) standards for biomass materials. Results indicate that hyparrhenia meets ASTM standards for particleboard raw materials, showcasing promising characteristics. The findings advocate for the ecological and economic benefits of hyparrhenia-based particleboard, addressing environmental threats and contributing to regional industrial development. Collectively, these findings underscore the potential of thatch grass as a promising and sustainable resource for particleboard production. The alignment with established standards in key properties, coupled with its regional abundance, positions thatch grass as a viable and environmentally friendly alternative for particleboard production. Further exploration and development in this direction could contribute to the expansion of biomass resources in the particleboard industry, fostering economic and ecological sustainabilit Description: scholarly works

Title: Cost-Benefit Analysis of IoT-Enhanced Maintenance: A Quantitative Assessment for Large-Format Printing Machine Authors: Ono, Chukwuma Godfrey; Godwin, Harold Chukwuemeka; Mgbemena, Chika Edith Abstract: This paper presents a comprehensive cost-benefit analysis of implementing Internet of Things (IoT)-enhanced maintenance strategies for large-format printing machines, with a focus on the Yinghe 6-feet printing machine at Chuxog Prints Limited, Awka, Nigeria. The study compares data before the implementation of IoT (referred to as pre-IoT) and after the deployment of IoT devices (referred to as post-IoT). By analyzing pre-IoT data (before IoT implementation) and postimplementation data, the study demonstrates significant reductions in maintenance frequency, technician labor costs, and machine component replacement expenses. Notably, the IoT system aided in minimizing wasted flex material and improved ink efficiency. Key findings include a 49.4% reduction in average monthly technician labor costs, a 93.9% reduction in average monthly machine component replacement costs, and an 87.6% reduction in wasted flex material. These findings have profound implications for industries relying on large-format printing machines, showcasing the potential for cost savings, increased efficiency, and extended equipment lifespan through IoT adoption. The paper concludes with a strong recommendation for organizations to consider IoT-enhanced maintenance strategies based on the observed empirical evidence, contributing invaluable insights to the optimization of maintenance practices in industrial settings.
