Applications of lean thinking: a briefing document

This report has been put together by the Health and Care Infrastructure Research and Innovation Centre (HaCIRIC) at the University of Salford for the Department of Health. The need for the report grew out of two main simple questions, o Is Lean applicable in sectors other than manufacturing? o Can the service delivery sector learn from the success of lean in manufacturing and realise the benefits of its implementation?The aim of the report is to list together examples of lean thinking as it is evidenced in the public and private service sector. Following a review of various sources a catalogue of evidence is put together in an organised manner which demonstrates that Lean principles and techniques, when applied rigorously and throughout an entire organization/unit, they can have a positive impact on productivity, cost, quality, and timely delivery of services

Software development: A paradigm for the future

A new paradigm for software development that treats software development as an experimental activity is presented. It provides built-in mechanisms for learning how to develop software better and reusing previous experience in the forms of knowledge, processes, and products. It uses models and measures to aid in the tasks of characterization, evaluation and motivation. An organization scheme is proposed for separating the project-specific focus from the organization's learning and reuse focuses of software development. The implications of this approach for corporations, research and education are discussed and some research activities currently underway at the University of Maryland that support this approach are presented

An assembly oriented design framework for product structure engineering and assembly sequence planning

The paper describes a novel framework for an assembly-oriented design (AOD) approach as a new functional product lifecycle management (PLM) strategy, by considering product design and assembly sequence planning phases concurrently. Integration issues of product life cycle into the product development process have received much attention over the last two decades, especially at the detailed design stage. The main objective of the research is to define assembly sequence into preliminary design stages by introducing and applying assembly process knowledge in order to provide an assembly context knowledge to support life-oriented product development process, particularly for product structuring. The proposed framework highlights a novel algorithm based on a mathematical model integrating boundary conditions related to DFA rules, engineering decisions for assembly sequence and the product structure definition. This framework has been implemented in a new system called PEGASUS considered as an AOD module for a PLM system. A case study of applying the framework to a catalytic-converter and diesel particulate filter sub-system, belonging to an exhaust system from an industrial automotive supplier, is introduced to illustrate the efficiency of the proposed AOD methodology

A modern approach on modeling the cost behavior by ABC/ABM method

The article intend to prove that the traditional methods of cost calculation do not correspond anymore to the actual principles imposed by the global economical competition which is focused more likely on the structure expenses, the conception period, the information sources and the value. The ABC method, the most popularized of all administration methods, presents the advantage of identifying the places where is found the origin of the waste, which are the activities with a low added value, where are located the unused capacities and how the costs are constituted. Adapted to the requirements of the Romanian economy, the ABC method can be applied in two stages, which are presented in the paper. There were identified the activities, the processes and the products and inside them, we proceeded to the modeling of the cost behavior, modeling which includes the EAD and APD concepts. The peculiarity of the method applied in the Romanian enterprise is that through the processing information, there can be determined the production cost for every line production, every activity, every floor, on the time unit (minute or hour) and on the product, as it is mentioned. By studying the specialty literature, we noticed some opinions regarding the possibility of integrating the ABC method with EVA, an aspect which is not possible, for now, to be applied to the studied enterprise. EVA remains an indicator for presenting financial performances through a new perspective, being useful especially for firms that perceive the capital as a source of funds without any costs and where the financial results are measured just through some profit indicators. The conclusion is that the utility of the method in taking strategic decisions regarding the selling cost and the best fabrication quantities remains uncertain because there can not be attached the principles of determining the breakeven point or the marginal contribution as long as the method does not allow the grouping of fixed and variable expenses. The solution could consist on developing a mixed alternative method which takes into consideration the activities behavior through which could be identified the cost of some specific activities that can allow determining the profitability of each product.cost, value, activities, process, performance, Romanian enterprise

Extending the enterprise: An evaluation of ERP and EAI technologies within a Case Study organisation

It is widely understood that both Information Technology (IT) and Information Systems (IS), provide great benefits in improving the visibility of supply and value chains within and across organisational boundaries. Those enterprises which can realise the benefits of extending their core business processes outwards to clients and trading partners, will be able to create unique supply chain-dependent products and solutions. Thus, such business infrastructures have enabled organisations to expand and improve the effectiveness of their enterprise. One method to achieve this, has been to integrate Enterprise Resource Planning (ERP) systems with web-based and other IS systems, using Enterprise Application Integration (EAI) technologies. This paper seeks to investigate those factors which contributed to a case organisation’s extended enterprise experiences, by using extant ERP and EAI implementation IS evaluation criteria; and by placing the research results within the context of applicable IS research techniques in the area

An approach to reconcile the agile and CMMI contexts in product line development

Software product line approaches produce reusable platforms and architectures for products set developed by specific companies. These approaches are strategic in nature requiring coordination, discipline, commonality and communication. The Capability Maturity Model (CMM) contains important guidelines for process improvement, and specifies "what" we must have into account to achieve the disciplined processes (among others things). On the other hand, the agile context is playing an increasingly important role in current software engineering practices, specifying "how" the software practices must be addressed to obtain agile processes. In this paper, we carry out a preliminary analysis for reconciling agility and maturity models in software product line domain, taking advantage of both.Postprint (published version

Diagnosing performance management and performance budgeting systems: A case study of the U.S. Navy

We present here a case study of an organization within the U.S. Navy that created a new organizational construct and performance management system. We explore the issues faced by naval leaders as they attempt to use their performance information to make resource allocation decisions at the sub-organization level, and base budgets at the organization and service (navy) level. We attempt to diagnose many of the practical problems a government organization encounters when implementing a performance management system, to include trying to inform budgets, and make recommendations on actions that would improve the strength of the performance system. We find in the organization a good conceptual framework, organizational enthusiasm, and reasonable attempts to link disparate information systems into a coherent whole. The good intentions are hindered, however, by inadequate accounting systems, a lack of understanding of cost accounting methods, weak use of terminology and longstanding institutional attitudes. This case confirms challenges associated with both performance management systems and performance budgeting found in the literature, and we offer recommendations for public officials considering such endeavors

A Preliminary Study of Applying Lean Six Sigma Methods to Machine Tool Measurement

Many manufacturers aim to increase their levels of high-quality production in order to improve their market competitiveness. Continuous improvement of maintenance strategies is a key factor to be capable of delivering high quality products and services on-time with minimal operating costs. However, the cost of maintaining quality is often perceived as a non-added-value task. Improving the efficiency and effectiveness of the measurement procedures necessary to guarantee accuracy of production is a more complex task than many other maintenance functions and so deserves particular analysis. This paper investigates the feasibility of producing a concise yet effective framework that will provide a preliminary approach for integrating Lean and Six Sigma philosophies to the specific goal of reducing unnecessary downtime on manufacturing machines while maintaining its ability to machine to the required tolerance. The purpose of this study is to show how a Six Sigma infrastructure is used to investigate the root causes of complication occurring during the machine tool measurement. This work recognises issues of the uncertainty of data, and the measurement procedures in parallel with the main tools of Six Sigma’s Define-Measure-Analyse-Improve-Control (DMAIC). The significance of this work is that machine tool accuracy is critical for high value manufacturing. Over-measuring the machine to ensure accuracy potentially reduces production volume. However, not measuring them or ignoring accuracy aspects possibly lead to production waste. This piece of work aims to present a lean guidance to lessen measurement uncertainties and optimise the machine tool benchmarking procedures, while adopting the DMAIC strategy to reduce unnecessary downtime

Life cycle assessment (LCA) applied to the process industry: a review

Purpose : Life cycle assessment (LCA) methodology is a well-established analytical method to quantify environmental impacts, which has been mainly applied to products. However, recent literature would suggest that it has also the potential as an analysis and design tool for processes, and stresses that one of the biggest challenges of this decade in the field of process systems engineering (PSE) is the development of tools for environmental considerations. Method : This article attempts to give an overview of the integration of LCA methodology in the context of industrial ecology, and focuses on the use of this methodology for environmental considerations concerning process design and optimization. Results : The review identifies that LCA is often used as a multi-objective optimization of processes: practitioners use LCA to obtain the inventory and inject the results into the optimization model. It also shows that most of the LCA studies undertaken on process analysis consider the unit processes as black boxes and build the inventory analysis on fixed operating conditions. Conclusions : The article highlights the interest to better assimilate PSE tools with LCA methodology, in order to produce a more detailed analysis. This will allow optimizing the influence of process operating conditions on environmental impacts and including detailed environmental results into process industry
