Abstract

Purpose

The purpose of this paper is to compare the well-known value stream mapping (VSM) with a recent tool named waste identification diagram (WID), regarding the capacity of information representation and easiness of interpretation.

Design/methodology/approach

The work begins with a brief literature review comparing the main tools for representation of production units, with special emphasis on VSM and WID, in terms of ability to identify several types of waste. Then, the authors developed the VSM and the WID of a specific production unit and after that several groups composed by students of Industrial Engineering (IE) and/or professionals from industry were asked to analyse/interpret only one of these diagrams. Finally, a questionnaire with closed and open questions was applied to the groups to evaluate the analysed tool.

Findings

In general, the results revealed that WID is more effective than VSM and participants recognized that most of the WID elements are relevant. Specifically, a measure coined overall effectiveness was applied (based on the response time and percentage of correct interpretations), indicating a clear advantage of WID (22 per cent of correct interpretations per minute) compared to VSM (9 per cent of correct interpretations per minute). The main drawback pointed to the WID is the lack of representation of the information flow.

Originality/value

This work contributes to the IE field by revealing WID as a new promising graphical tool for representation of production units, especially in terms of identification/quantification of wastes. The tool was quantitative and qualitatively evaluated by persons both from academia and industry.

Abstract

Purpose

This paper aims to assess the needs for a lean continuous improvement professional certificate and/or lean leadership cognate for a Doctorate of Education in leadership focused in three main research questions: “What do organizational leaders need from a Lean graduate programming?”; “What are the preferable methods of delivery for Lean teaching/learning?” and “What are the main learner outcomes and do how these impact organizational and continuous improvement outcomes?”

Design/methodology/approach

A survey to 37 organizational leaders in a North-American state was conducted via telephone and email that were returned to the researcher. The survey was designed to target a solid cross-section of organizational decision makers in regard to the need for and type of lean training desired, if at all, for employees. Using a mixed methods approach, the survey was designed to collect both qualitative and quantitative information.

Findings

Respondents indicated that lean continuous improvement thinking and lean process-project management were most the desirable content options. The method of delivery was not as clear with on-ground and online relying on job-embedded, project-based methods as most desirable approaches. Learner outcomes of mastery of lean content along with the ability to impact organizational and continuous improvement outcomes were favored.

Originality/value

Lean leadership education is valued learning by organizational leaders. As so, higher education institutions must be aware of matching better organizational needs with learning experiences. This paper presents a survey that intended to do this in an original way.
