Demystifying the eighth lean waste: a knowledge waste scale

Abstract

PurposeSince few studies have explored and advanced on the development of measures of knowledge waste, the purpose of this paper is to develop and validate a scale for measuring the waste of knowledge.Design/methodology/approachA research was carried out in Higher Education Institutions (HEIs) divided into five distinct stages, three qualitative and two quantitative. For the quantitative steps, a sample of 223 responses was obtained for the exploratory part and another sample of 614 responses for the confirmatory part of the study. Data analysis procedures involved Exploratory and Confirmatory Factor Analysis to test and validate the proposed scale.FindingsA fifteen-item scale divided into four constructs was obtained after refinement of the proposed scale and validation procedures (convergent and discriminant validity). The scale also has satisfactory levels of reliability.Research limitations/implicationsThe resulting scale was validated in a single institutional culture environment (HEIs in Southern Brazil). So it still should be tested in different organizational contexts and cross-culturally in different countries. The scale may be useful for decision-making improvement about knowledge management and waste reduction.Practical implicationsA scale with a practical and quick application is provided. Additionally, a classification of the waste of knowledge level was developed and it could be easily applied in different sectors or organizations.Originality/valueThe literature on waste of knowledge is limited and often confused with knowledge loss. This study provides a clear distinction between these topics, and it advances on the explanation and definition of knowledge waste. Also, it is the first study to offer a scale to measure the elements of knowledge waste.
