Using simulation to assess the introduction of technology in a continuous operations process

Purpose – To investigate the role of simulation in the introduction of technology in a continuous operations process. Design/methodology/approach – A case-based research method was chosen with the aim to provide an exemplar of practice and test the proposition that the use of simulation can improve the implementation and running of conveyor systems in continuous process facilities. Findings – The research determines the optimum rate of re-introduction of inventory to a conveyor system generated during a breakdown event. Research limitations/implications – More case studies are required demonstrating the operational and strategic benefits that can be gained by using simulation to assess technology in organisations. Practical implications – A practical outcome of the study was the implementation of a policy for the manual re-introduction of inventory on a conveyor line after a breakdown event had occurred. Originality/value – The paper presents a novel example of the use of simulation to estimate the re-introduction rate of inventory after a breakdown event on a conveyor line. The paper highlights how by addressing this operational issue, ahead of implementation, the likelihood of the success of the strategic decision to acquire the technology can be improved.

Professionals, discretion and public sector reform in the UK:re-visiting Lipsky

Purpose – Seeks to examine how far Michael Lipsky's theory of discretion as it relates to public sector professionals as “street-level bureaucrats” is still applicable in the light of public sector reform and in particular the introduction of increased managerial control over professionals. Design/methodology/approach – The main thesis in Lipsky's work, Street-Level Bureaucracy, that street-level bureaucrats devise their own rules and procedures to deal with the dilemmas of policy implementation is linked to public sector reform over the past 25 years or so. The article differentiates between three forms of discretion, rule, task and value and assesses the extent to which these different forms of discretion have been compromised by reform. Examples are drawn principally from the literature on school teachers and social workers Findings – The findings suggest that the rule-making (hence bureaucratic) capacity of professionals at street-level is much less influential than before although it is questionable whether or not the greater accountability of professionals to management and clarity of the targets and objectives of organisations delivering public policy has liberated them from the dilemmas of street-level bureaucracy. Research limitations/implications – The work has focussed on the UK and in particular on two professions. However, it may be applied to any country which has undergone public sector reform and in particular where “new public management” processes and procedures have been implemented. There is scope for in-depth studies of a range of occupations, professional and otherwise in the UK and elsewhere. Practical implications – Policy makers and managers should consider how far the positive aspects of facilitating discretion in the workplace by reducing the need for “rule-making” to cope with dilemmas have been outweighed by increased levels of bureaucracy and the “de-skilling” of professionals. Originality/value – Lipsky's much cited and influential work is evaluated in the light of public sector reform some 25 years since it was published. The three forms of discretion identified offer the scope for their systematic application to the workplace.

Introduction to the special issue : reframing German Federalism

In recent years, Germany’s federal system has been subject to a number of pressures for change. A constitutional debate on ‘disentangling’ the legislative roles of federal and Länder institutions which stuttered through the 1990s and into the 2000s finally led to a re-allocation of competences in 2006. These reforms shifted some areas of legislative responsibility from the federal to the Länder level and relaxed rules which had earlier justified a federal override when both levels held legislative responsibilities concurrently. At the very least, these constitutional adjustments increased the potential for policy outputs to diverge from one Land to another and give expression to territorial differences in priority and preference.
