Pencil and paper: the simple solution to getting the numbers you need to effectively manage your practice

Once you have mastered the basics by going through the monitoring exercise once or twice, you will find it takes little time and effort to start finding out just where your practice stands. You only solve a problem after you have found out that there is one and you might find that this simple monitoring exercise shows you areas of your practice where a little attention from you will pay big dividends. Monitoring is like a fine wine: it improves with age. As you begin to compile more and more months of data, you will be able to start comparing this month's performance with last month's, or this quarter with last quarter, this year with last year. One of the most useful things monitoring will do for you is to allow you to compare your practice's performance with that of other practices. Averages, norms, and performance survey results are to be found in a range of practice management publications. Using your monitoring information in this comparative way helps you to identify those areas in your practice management that are holding you back from achieving your true potential. This lets you focus your management time and effort on the truly important issues, which, when solved, will help you turn your practice into a less stressful, more enjoyable, and more profitable place to work.

Delay Mitigation in the Malaysian Construction Industry

This paper describes the importance of applying proper management in dealing with delays in construction for a growing economy. The main objective of this paper is to identify the management tools that are practiced in the local construction industry in mitigating delay. It also aims to identify the main factors that lead to project delays and to suggest recommendations on how to overcome or mitigate effects of the problem. Data is gathered from responses from questionnaire survey and interviews with those involved in construction project. The surveys and research findings indicate that delay incidents occur mainly during the construction phase of a project and one or more parties usually contribute to delay. This paper highlights the importance of having more experienced and capable construction managers as well as skilled laborers to enable the industry to develop at a faster rate either nationally or internationally.     

Greenhouse gases and the metallurgical process industry

The Kyoto Protocol of December 1997 highlighted the importance of greenhouse gas emissions. The metallurgical process industry is a contributor to these emissions and would be seriously affected by measures curtailing them. The present lecture offers a brief review of the greenhouse effect, the sources of greenhouse gases, the potential effect of these gases on global warming, the response of the international community, and the probable cost of national compliance. The specific emissions of the metallurgical process industry, particularly those of the steel and aluminum sectors, are then examined. The potential applications of life-cycle assessments and of an input-output model in programs of emissions’ abatement are investigated, and, finally, a few remarks on some implications for education are presented. Thank you for the honor and the pleasure of addressing you today. I am indeed grateful. I have chosen to speak on greenhouse gases and the metallurgical process industry, because I believe the issue is topical and I hope you will find it of interest. A comprehensive analysis of such a vast subject is clearly beyond the scope of this lecture. I have chosen instead to give you a brief overview of the situation and to examine a few particular points. As you are well aware, in the last three decades, the metallurgical industry has been faced with an explosion of environmental laws and regulations. Greenhouse gases and global warming appear to represent the next threat. That threat generates a wide spectrum of reactions, from concerned interest to indignant incredulity. I propose to start with a quick review of the greenhouse effect, the sources of greenhouse gases, the potential effect of these gases on global warming, the response of the international community, and the probable cost of national compliance. I shall then focus on the metallurgical process industry (mostly the steel and aluminum industries), and investigate the possible usage of life-cycle assessments as well as the potential of an input-output model for the analysis of various alternatives. I will also make a few remarks on certain implications for education.

Lawyerization of the Engineering and Construction Industry

Lawyerization has become more and more prevalent in the engineering and construction industry. Some would argue the merits of firms’ retaining lawyers on staff as providing cost savings on projects through averting potential litigation. Others view lawyers as increasing project costs due to increased overhead. Therefore, it is important to understand the pros and cons of lawyerization as viewed by the contractor, designer, owner, manufacturer, and supplier. This paper discusses the current role of lawyers in the engineering and construction industry and examines the factors that contribute to the lawyerization of the industry.
