Towards digitalisation of quality management: conceptual framework and case study of auto-component manufacturer

Purpose

Industry 4.0-driven digitalisation is said to offer a way to redesign traditional compliance-oriented quality management (QM) models. However, despite a rising academic and practitioner interest, it is still unclear how companies transform their current QM models to meet the real-time needs of the new manufacturing paradigm. The purpose of this study is to explore practices for the digitalisation of QM and to uncover the digitalisation journey.

Design/methodology/approach

An exploratory research approach of an embedded case study of a multinational auto-component manufacturer was adopted to achieve the research aim.

Findings

A guiding framework called the “Quality 4.0 transition framework” was developed based on literature and expert knowledge. The framework is made up of three building blocks, i.e. the foundation of “as-is” digitalisation maturity assessment; pillars representing horizontally and vertically integrated QM processes, and roof signifying reinforcement of total quality management (TQM) principles at all levels.

Originality/value

The study provides empirical evidence of the case company's digitalisation journey to avert product recall due to field failure issues. The study contributes to theory and practice in many ways. First, the study uses empirical data from a real-world case to understand how digitalisation affects QM processes. Next, the guiding framework for the Quality 4.0 transition adds to the existing literature on the digitalisation of business processes.

Board gender diversity: implications for environment, social, and governance (ESG) performance of Indian firms

Purpose

The purpose of this article is to explore the phenomena of board gender diversity and its consequences for sustainability performance, as measured by the environment, social and governance (ESG) disclosure score, in the Indian context.

Design/methodology/approach

The positivist paradigm influenced the research design for this study. The relationship between firm's ESG performance and female participation on the corporate boards was explored using panel data regression with a fixed effect approach. A total of 712 data points covering the Nifty 100 companies of the National Stock Exchange (NSE) were included in the data set. To add robustness to the findings and to overcome endogeneity bias, authors employed the Dynamic Generalized Method of Moments (GMM).

Findings

The results showed that, a relatively small, percentage of women directors has little impact on ESG performance, but when at least three women directors are in place, these relationships become more favourable. Despite the fact that Indian firms trail behind many developed and developing countries in promoting board gender equality, authors conclude that critical mass theory partially applies in the Indian context.

Originality/value

This study contributes to the field of corporate governance in the twenty-first century by investigating the subject of women's participation on boards in the context of a rising market and its potential influence on sustainability performance. The use of critical mass theory adds a fresh perspective to the literature.

State and citizen responsiveness in fighting a pandemic crisis: A systems thinking perspective

Management scholars have recognized organizational responsiveness among the essential capabilities of social organizations. It becomes essential for a social change to occur during a crisis, where the uncertainty or environmental dynamism is high. However, a social change cannot be successful unless constituent subsystems of a social organization exhibit responsiveness. Using systems theory, we conceptualize 'nation' as a social system and examine its responsiveness towards environmental uncertainly, taking an example of the COVID-19 pandemic. How can state and citizen community responsiveness help fight a pandemic crisis? We test these direct and moderating effects on data representing 14 countries. We perform a hierarchical regression analysis on the restructured, balanced country-wise panel data. Our findings highlight the importance of state and community interaction effects in controlling pandemic growth. Accordingly, we claim that only a collaborative approach by citizen communities with the respective governments will enable handling an uncertain situation.

Supply chain sustainability drivers for fast-moving consumer goods (FMCG) sector: an Indian perspective

Purpose

: Sustainability in fast-moving consumer goods (FMCG) supply chains (SC) is receiving greater than ever attention due to the increasing awareness of sustainability challenges such as climate change and labor rights. A definite solution is to integrate sustainable supply chain management (SSCM) practices all through the upstream and downstream entities of SC. This study identified and compared the drivers for the implementation of SSCM practices in Indian FMCG sector.

Design/methodology/approach

A methodology based on Grey-Decision Making Trial and Evaluation Laboratory (DEMATEL), a hybrid multiple-criteria decision making (MCDM) technique and sensitivity analysis was used to envisage the complex causal relationships among the identified SSCM drivers and to identify the critical ones.

Findings

The results showed that regulatory and legislative pressure, competition pressure and innovativeness dominantly drive the implementation of SSCM practices in the upstream and downstream SC of the FMCG sector.

Originality/value

The study examined levers of sustainability in FMCG supply chains in an emerging market with most of the extant research limited to automotive and electronic supply chains.

Quality management in industry 4.0 environment: a morphological analysis and research agenda

Purpose

Digitalised and interconnected production systems in the era of fourth industrial revolution or Industry 4.0 (I4.0) have triggered the need of reshaping the traditional Quality Management (QM) models and roles of quality professionals. The purpose of this paper is to review the body of literature on QM in the I4.0 environment (also termed as “Quality 4.0”) and identify future research possibilities.

Design/methodology/approach

The morphological analysis (MA) framework is used to identify research gaps in a systematic manner. We present the MA framework based on a literature review of 51 papers on the Australian Business Deans Council (ABDC) list identified using systematic review protocol.

Findings

The MA framework, built on six relevant dimensions, namely, production and operations function, scope of QM activities, enabling technologies, latent capabilities of digitalisation, performance metrics and QM principles, and 41 associated variants, reveals 367 research gaps as an upper bound of opportunities for future research.

Originality/value

This paper is possibly the first to use MA for reviewing the QM literature, presenting important contributions. The MA framework acts as a ready reckoner on the QM in I4.0 literature. It documents research gaps through the construction of a cross-consistency matrix.

Moderating effects on sustainability reporting and firm performance relationships: a meta-analytical review

Purpose

The past sustainability literature on the effects of nonfinancial disclosures on a firm's performance is highly fragmented. Thus, the authors raise the following research questions to test potential differences: Is sustainability reporting (SR) based on the Global Reporting Initiative (GRI) or other systematic reporting framework associated with firm performance? Does quality or level of SR impact firm performance? Do firm-, industry- and country-level factors moderate the effect of SR on firm performance? Does the presence of publication bias affect this relationship?

Design/methodology/approach

Meta-analysis technique suggested by Hedges & Olkin (1985) was used to analyze a sample of 98 effect sizes reported in 60 studies published between 2010 and 2020 studying SR–performance associations. Meta-regression and subgroup analyses were used to investigate the moderating variables accounting for this heterogeneity in the relationship.

Findings

Results reveal that level and quality of SR influence the market-, accounting- and operational-based measures of firm performance. Meta-regression results depict that for large, matured firms, or the ones with institutional investors as board members or the ones that actively participate SR quality awards, SR translates better into firm performance. Subgroup analyses demonstrate that the SR–firm performance relationship is moderated by the corporate governance (CG) system of the country and the firm's affiliation to environmentally sensitive industries.

Originality/value

These findings extend theoretical and practical understanding on effects of corporate sustainability communications on performance.

Quality management for high-contact professional service firms: a multiple-case evidence from Indian law firms

Purpose

This paper presents an exploratory study to understand the distinctive quality dimensions of high-contact Professional Service Firms (PSFs) and develop a conceptual model for Quality Management (QM). The paper is based on empirical evidences from multiple cases in leading Indian law firms.

Design/methodology/approach

The paper adopted an exploratory, multiple, embedded and comparative case study design. The empirical evidence from multiple case studies in 10 law firms (data includes 42 individual interviews, archival records, field notes) was used to explore the QM dimensions for PSFs.

Findings

The results showed that QM in PSFs is a multifaceted and continuous process rather than a straightforward and episodic one. The findings reveal three distinctive dimensions of QM for PSFs: managing the firm's image; managing the client-firm interaction and support processes and; managing the perceived value of service outcome. Further, the results showed a significant variation in the design of QM practices in a relatively homogenous group of PSFs (law firms). This reflected the influence of personnel and organizational characteristics on the QM.

Research limitations/implications

The research is based on evidences collected from 10 Indian law firms and the research design is exploratory in nature. The future research is suggested in terms of extending the scope and research design.

Practical implications

The insights obtained from the paper have implications for managers working on the design of service operations and particularly service quality in high-contact PSFs similar to law firms. While the study does not prescribe a standard design of QM systems for PSFs, it seeks to foster the thinking of managers by helping them conceptualize the broad quality-control checkpoints and quality attributes specific to PSF settings

Originality/value

The academic research in the management of professional service quality is dominated by conceptual/theoretical models for customer evaluation of service provider's performance and the issue of operationalization of QM in PSFs is still needs further investigation. This paper contributes to the theory of service operations management (SOM) by focusing on the structure of QM systems in PSFs.

Adopting Six Sigma DMAIC for environmental considerations in process industry environment

Purpose

The aim of the study is to develop and apply a continuous improvement (CI) framework by introducing environmental considerations into the Six Sigma DMAIC (define–measure–analyze–improve–control) cycle for a continuous identification, evaluation and implementation of promising opportunities of enhancing environmental sustainability of process-based industries.

Design/methodology/approach

Action research approach within the research design of a single case study was used for illustrating the application of the proposed DMAIC framework for improving operational and environmental performance in the process-industry environment of a pharmaceutical manufacturing company.

Findings

The case study illustrated the implementation of DMAIC cycle for optimizing the energy consumption of pharmaceutical plants producing bulk drugs for medication. After improving the energy distribution in the cooling tower (CTW), chilled brine (CHB) and chilled water (CHW) system, the pharmaceutical plant was able to achieve an annual economic benefit of US$97,047 and environmental benefits of mitigating CO2 emissions of 807.44 t (CO2) by reducing the electricity and furnace oil consumption.

Originality/value

The framework may be adopted for environmental considerations specific to process-based industry such as chemical plant, fertilizer units, thermal power plant and food processing industry.

Modeling enablers of supply chain quality risk management: a grey-DEMATEL approach

Purpose

The purpose of this paper is to recognize and model the enablers of supply chain quality risk management (SCQRM) through an empirical study in the Indian automotive companies.

Design/methodology/approach

A systematic literature review was conducted to extract the key enablers of quality management (QM) and risk management in the context of manufacturing supply chains. A grey-based DEMATEL method was employed to identify and model the key enablers of SCQRM.

Findings

The results of empirical study showed that the effectiveness of QM and risk management systems for automotive supply chain is driven by a set of common enablers that could be employed for developing dedicated SCQRM systems. The common causal factors in the model such as the involvement of top leaders, inter-firm communication and strategic-level alignment between supply chain members on both these issues clearly state that there is a need for a broader policy at an early stage.

Practical implications

It is crucial for the automotive companies to develop and implement structured systems for SCQRM keeping in view the impact of any unaddressed quality risk on missed production targets, vehicle recalls and safety hazards.

Originality/value

This study ascertains the key enablers of SCQRM with emblematic focus on automotive industry and identifies if there are commonalities in these enablers.

Assessment of pattern and outcomes of pesticides poisoning in a tertiary care hospital

OBJECTIVES

To assess the socio-demographic profile, pattern and treatment outcomes of pesticides poisoning.

METHODS

A prospective observational study was conducted at the department of emergency medicine of a South Indian tertiary care hospital for 1.5 years to study the pattern and outcomes of poisoning cases due to pesticides. Level of significance (P) <0.05 was considered as statistically significant.

RESULTS

A total of 375 poisoning victims with intentional/accidental exposure to pesticides were followed up and documented. The male-female ratio was 1:0.32; mean age was 31.65 ± 13.10 years. 72% of cases were rural residents. Organophosphorus compounds were the most implicated pesticides. Mean Glasgow Comatose Score (GCS) of the patients was 12.22 ± 3.86. 80.3% of patients recovered while 6.4% died. About 13.3% patients were lost to follow-up as they were discharged against medical advice (DAMA).

CONCLUSION

There was a statistical significance seen in the implication of pesticides for intentional poisoning with age, route of administration, area of residence and occupation of the victims. However, there was a strong association of the outcomes of poisoning with the toxic agent implicated for the poisoning.

Integration of Taguchi and Shainin DOE for Six Sigma improvement: an Indian case

Purpose

The purpose of this paper is to demonstrate the application of Six Sigma/design of experiments (DOE) hybrid framework for improving damping force (DF) generation process in a shock absorber assembly unit.

Design/methodology/approach

The study adopted a case study research method with single case (holistic) design. This research design was found to be appropriate for testing the projected framework for integrating DOE approaches within Six Sigma define-measure-analyze-improve-control (DMAIC) cycle. In the proposed framework, Shainin’s component search technique (CST) was deployed at the “analysis” phase of DMAIC for the first stage filtering of process parameters, followed by the use of Taguchi orthogonal arrays (OA) at the “improve” phase for identifying the optimal setting of the parameters.

Findings

The application of Shanin CST facilitated in ascertaining that assembly component (piston with rebound stopper) was causing the variation and not the assembly process. Further, the use of Taguchi OA at the improve phase allowed the collection of necessary data to determine the significant piston parameters with minimum experimentation (eight experimental runs in this case as opposed to the expected 64) and analysis of variance on the collected data facilitated the selection of parameter settings to optimize the “critical to quality”, i.e. rebound DF.

Originality/value

This study provided a stimulus for wider application of integrated DOE approaches by the engineering community in the problem solving and the identification of parameters responsible for poor performance of the process.

Redesigning an assembly line through Lean-Kaizen: an Indian case

Purpose

– The purpose of this paper is to address the adoption of Lean-Kaizen approach to process improvement by the largest manufacturer of steering systems for passenger car and utility vehicle market in India. The company was facing severe liquidity crunch due to falling customer demand (25 percent lower than forecasted), rising cost of raw material and bank borrowing rates. In order to survive in such stiff scenario, the company systematically deployed Kaizen events and drastically improved their internal efficiency.

Design/methodology/approach

– The study categorically illustrates the employment of value stream mapping (VSM) to target the areas for Kaizen improvement events. Current state VSM was developed to display the non-value-added activities in the existing assembly process. Future state VSM was proposed. After identifying root cause of wastes using 5 Why, three Kaizen events were proposed.

Findings

– The current state VSM revealed cumulative inventory of 61 days in the entire process, long distances travelled by subassembly for final assembly (294 meters) and a high defect rate (879 parts per million). After modifying the assembly line using lean strategies, the company reduced its inventory levels by 66 percent, defect rate reduced by 32 percent and achieved other benefits such as reduced equipment, production staff and storage space. These reductions helped the company in saving the working capital and also contributed significantly to its profitability.

Originality/value

– The study exhibits implementation of Lean-Kaizen approach for redesigning assembly line in an auto component manufacturing unit. The proposed lean strategies are considered to be highly valuable for manufacturer of steering for passenger cars and utility vehicles market.

Measurement of intraocular pressure (IOP) in chickens using a rebound tonometer: quantitative evaluation of variance due to position inaccuracies

Intraocular pressure (IOP), an important risk factor for glaucoma, is a continuous trait determined by a complex set of genetic and environmental factors that are largely unknown. Genetic studies in laboratory animals may facilitate the identification of genes that affect IOP. We examined the use of the rebound tonometer for measuring IOP in non-anaesthetised birds, along with the device's robustness to alignment errors. Calibration curves were obtained by measuring the IOP of cannulated chicken eyes with the rebound tonometer over a range of pressures. To simulate different types of alignment errors that might be expected with measurement of IOP in alert chickens, for some calibrations the tonometer was positioned (1) at various distances from the cornea, (2) laterally displaced from the visual axis, or (3) angled away from the visual axis. In vivo measurements were taken on three-week-old alert chickens from a layer line, a broiler line, and a layer-broiler "advanced intercross line" (AIL) designed to facilitate QTL mapping. The rebound tonometer showed excellent linearity (R2=0.95-0.99) during calibration, as well as robustness to variation in the probe-to-cornea distance over the range 3-5mm and to lateral displacement over the range 0-2mm. However, the tonometer appeared less robust to off-axis misalignment over the range 0-20 degrees (P<0.05). Also, the slope of calibration curves sometimes differed between eyes (P<0.001), presumably reflecting differences in ocular structure. The IOP measured in non-anaesthetised three-week-old AIL chickens was 17.51+/-0.13 mmHg (mean+/-S.E.; N=105 birds). IOP was significantly associated with corneal thickness (P<0.05) and body weight (P<0.001) in a regression model. Replicate measurements were necessary in order to gauge IOP accurately in individual birds; a series of seven tonometry sessions over a 12-h period during the light phase of the light/dark cycle permitted IOP to be measured with a 95% CI of +/-0.7 mmHg. IOP did not differ significantly between the broiler and layer chicken lines which served as the progenitor lines for the AIL. In conclusion, the rebound tonometer permits rapid estimation of IOP in chickens and is well tolerated. The small alignment errors that are expected when taking measurements in non-anaesthetised animals are unlikely to affect accuracy. Since high IOP is a major risk factor for glaucoma, identifying QTL controlling IOP may offer future health benefits. However, our preliminary findings highlight several obstacles to mapping such QTL using the chicken advanced intercross line evaluated here.

Cytotoxicity of clove (Syzygium aromaticum) oil and its major components to human skin cells

The essential oil extracted from clove (Syzygium aromaticum) is used as a topical application to relieve pain and promote healing in herbal medicine and also finds use in the fragrance and flavouring industries. Clove oil has two major components, eugenol and beta-caryophyllene, which constitute 78% and 13% of the oil, respectively. Clove oil and these components are generally recognized as 'safe', but the in-vitro study here demonstrates cytotoxic properties of both the oil and eugenol, towards human fibroblasts and endothelial cells. Clove oil was found to be highly cytotoxic at concentrations as low as 0.03% (v/v) with up to 73% of this effect attributable to eugenol. beta-caryophyllene did not exhibit any cytotoxic activity, indicating that other cytotoxic components may also exist within the parent oil.

Cytotoxicity of lavender oil and its major components to human skin cells

Lavender (Lavandula angustifolia) oil, chiefly composed of linalyl acetate (51%) and linalool (35%), is considered to be one of the mildest of known plant essential oils and has a history in wound healing. Concerns are building about the potential for irritant or allergenic skin reactions with the use of lavender oil. This study has demonstrated that lavender oil is cytotoxic to human skin cells in vitro (endothelial cells and fibroblasts) at a concentration of 0.25% (v/v) in all cell types tested (HMEC-1, HNDF and 153BR). The major components of the oil, linalyl acetate and linalool, were also assayed under similar conditions for their cytotoxicity. The activity of linalool reflected that of the whole oil, indicating that linalool may be the active component of lavender oil. Linalyl acetate cytotoxicity was higher than that of the oil itself, suggesting suppression of its activity by an unknown factor in the oil. Membrane damage is proposed as the possible mechanism of action.

Urinary bladder dysfunction in the BB/W diabetic rat: effect of ganglioside treatment on functional and structural alterations

Urinary bladder dysfunction in the diabetic BB/W rat is characterized by infrequent irregular contractions of high amplitude. Initially these occur in the absence of detectable neuroanatomical lesions of sensory afferent and parasympathetic fibers of the pelvic nerve, which constitute the micturition reflex arc. Structural lesions consisting of progressive axonal atrophy of myelinated and unmyelinated fibers become detectable only after 4 months of diabetes. In the current study we evaluated the effect of ganglioside treatment (10 mg./kg. body weight) for one month. This drug regimen was initiated at 4 months of diabetes, when functional bladder abnormalities were well established, whereas structural lesions were yet to appear. Animals examined 1 or 3 months after termination of the one-month treatment protocol showed sustained normalization of the characteristic functional abnormalities, accompanied by prevention of the neuroanatomical lesions of sensory afferent and parasympathetic efferent myelinated fibers in the pelvic nerve. These data suggest that ganglioside treatment may be beneficial in delaying the progression of diabetic autonomic neuropathy in this experimental animal model.

Overt diabetic neuropathy: repair of axo-glial dysjunction and axonal atrophy by aldose reductase inhibition and its correlation to improvement in nerve conduction velocity

Clinically overt diabetic neuropathy is characterized by neuroanatomical changes of the node of Ranvier and myelinated axons, and by decreased nerve conduction velocity. Sural nerve biopsies were obtained from 16 neuropathic diabetic patients participating in a 12-month randomized, placebo-controlled, double-blind clinical trial of the aldose reductase inhibitor sorbinil. One sural nerve biopsy was obtained at baseline and a second biopsy at the termination of the trial. Ten sorbinil-treated patients showed significant improvement in axo-glial dysjunction, a characteristic lesion of the node of Ranvier. Axonal atrophy assessed by three independent morphometric techniques also exhibited significant recovery in the sorbinil-treated patients. No change was demonstrated in any of these structural parameters in six placebo-treated patients. The improvement in sural nerve conduction velocity in sorbinil-treated patients correlated with the product of the quantitative improvements in axo-glial dysjunction and axonal atrophy. We conclude that the activated polyol-pathway plays a sustaining role in nerve fibre damage in diabetic neuropathy, and that structural lesions such as axo-glial dysjunction and axonal atrophy which are reversible following intervention with an aldose reductase inhibitor, constitute the morphological basis for nerve conduction slowing in overt diabetic neuropathy.

The reproducibility and sensitivity of sural nerve morphometry in the assessment of diabetic peripheral polyneuropathy

The nerve fibre loss, atrophy and injury of diabetic peripheral polyneuropathy and their responses to metabolic intervention have been studied by morphometric analysis of sural nerve biopsies. The magnitudes and sources of intra- and inter-individual variation in these morphometric measures have not been investigated previously in a systematic manner. Morphometric parameters of nerve fibre damage were measured in four separate fascicles from bilateral sural nerve specimens obtained post-mortem from 13 diabetic and 13 non-diabetic subjects. Intra- and inter-individual coefficients of variation were computed and compared to the magnitude of the differences between normal and diabetic subjects. Several morphometric variables emerged as highly sensitive and reproducible measures of nerve fibre damage suitable for clinical studies of diabetic peripheral polyneuropathy. These observations provide a rational basis for the design of future clinical trials employing morphometric end-points.

Endoneurial microvessels in human diabetic neuropathy. Endothelial cell dysjunction and lack of treatment effect by aldose reductase inhibitor

Endoneurial microvascular abnormalities have been invoked in the pathogenesis of diabetic distal symmetric polyneuropathy. Detailed morphometric analysis of the endoneurial microvasculature was correlated with previously published data on nerve fiber morphometry and teased fiber analysis obtained from the same sural nerve biopsies. Biopsy specimens from neuropathic diabetic patients were obtained before and after 12 mo of aldose reductase inhibitor (ARI) treatment and compared to 15 carefully age-matched control subjects. Diabetic microvessels showed basement membrane thickening and loss of endothelial cell tight junctions. Microvascular density and the frequency of microvessels closed by endothelial cells increased with age in diabetic and control nerves and were unaffected by diabetes. The density of microvessels showing patent lumina did not differ between control and diabetic subjects and was not related to age or diabetes. Closed microvessels were composed of postcapillary venules that were otherwise devoid of ultrastructural abnormalities. We suggest that microvascular closure by endothelial cells may be a physiological condition and is unlikely to have any pathogenetic significance in diabetic neuropathy. Based on the current limited biopsy material, we conclude that 12 mo of ARI treatment that induced significant fiber repair and regeneration had no detectable effect on endoneurial microvascular abnormalities. These data suggest that endoneurial vascular pathology is not a rate-limiting factor in fiber damage or repair at this stage of diabetic neuropathy.

Preventive effect of long-term aldose reductase inhibition (ponalrestat) on nerve conduction and sural nerve structure in the spontaneously diabetic Bio-Breeding rat

To test the hypothesis that aldose reductase inhibition may prevent or delay the development of functional and structural neuropathy in the insulin-deficient diabetic Bio-Breeding rat (BB-rat), hyperglycemic rats were begun on the aldose reductase inhibitor (ARI) ponalrestat 25 mg/kg body wt soon after the onset of diabetes and followed for 4 or 6 mo. Ponalrestat treatment completely prevented the characteristic nerve conduction slowing and structural abnormalities of the node of Ranvier for 4 mo despite only partial preservation of axonal integrity. Ponalrestat treatment for 6 mo achieved a partial but significant prevention of nerve conduction slowing, axoglial dysjunction, and axonal degenerative changes. This incomplete but significant prevention of neuropathy by ponalrestat suggests that additional mechanisms besides polyol-pathway activation may be of importance in the pathogenesis of diabetic neuropathy. Alternatively, the dosage used in the present study may not have been sufficient to achieve a complete prevention. Despite the only partial protective effect of ARI treatment on degenerative peripheral nerve changes in hyperglycemic BB-rats, 6 mo of treatment resulted in a more than threefold increase in regenerating nerve fibers. These data suggest that prophylactic ARI treatment may be efficacious in delaying the development of diabetic neuropathy.
