Improving Design of Micro-business Systems via VSM and Constituent Orientation Analysis

This paper describes recent design research into prototypical ‘classes’ of designs for operational business systems for micro-businesses of 1-10 employees typical of traditional craft and contemporary information economies. Business process design is an increasingly important and relatively new sub-field of design and design research. Its increasing importance is driven by three factors made more potent by information technology: increasing ability for very small business units to contribute to local and national economies; potential for increased efficiency of micro-businesses via reduction in Coasian transaction costs; increasingly competitive business environments leading to pressure on micro-businesses to deeply cut costs; and increased potential for improved design of micro-business processes to create significant benefits for the micro-businesses themselves and to local and national economies. The analyses used in this paper combine Tellefsen's perspective on constituent orientation with Beerian Viable System analysis and Cashflow Quadrant analysis (Beer, 1972, 1988, 1989, 1995; Kiyosaki & Lechter, 2007; Tellefsen, 1995, 1999, 2001; Tellefsen & Love, 2003). These analyses are used to identify promising foci of design effort particularly with the intention of automating and systematizing business activities. The paper first describes the importance of developing improved guidelines for design of organisational structures and business processes in the micro-business arena. It then outlines the structural, humanistic, financial, business management and computerized automation considerations that need to be addressed. Design issues are illustrated via mini case studies of three characteristic micro-businesses in the areas of publishing, plumbing, and rental investment. The paper shows how improvements to the design of business processes can be viewed through how four constituent orientations: • Self employed • Business managers • Business owners • Investors The paper concludes by integrating the outcomes of the above analyses into a preliminary checklist for the design of effective and efficient automated and systematized business processes for micro-businesses and small business enterprises.

Use of satellite data and modeling to assess the influence of stratospheric processes on the troposphere

Over the past forty years, numerous linear stability studies have been performed in order to explain the origin and structure of observed waves in the atmosphere. Of these studies, only a small fraction have considered the stability of time-dependent, zonally varying flow or the influence of radiative-photochemical feedbacks on the stability of zonally uniform flow. The stability of such flows is described, and these flows may yield important information concerning the origin, structure, and transient time scales of free waves in the atmosphere. During the period 1990 to 1991, a beta-plane model that couples radiative transfer, ozone advection, and ozone photochemistry with the quasigeostrophic dynamical circulation was developed in order to study the diabatic effects of Newtonian cooling and ozone-dynamics interaction on the linear stability of free planetary waves in the atmosphere. The stability of a basic state consisting of a westward-moving wave and a zonal mean jet was examined using a linearized, nondivergent barotropic model on sphere. The sensitivity of the stability of the flow to the strength and structure of the zonal jet was emphasized. The current research is focused on the following problems: (1) examination of the finite amplitude interactions among radiation, ozone, and dynamics; and (2) examination of the role of seasonal forcing in short-term climate variability. The plans for next year are presented

Life cycles of transient planetary waves

In recent years there has been an increasing effort devoted to understanding the physical and dynamical processes that govern the global-scale circulation of the atmosphere. This effort has been motivated, in part, from: (1) a wealth of new satellite data; (2) an urgent need to assess the potential impact of chlorofluorocarbons on our climate; (3) an inadequate understanding of the interactions between the troposphere and stratosphere and the role that such interactions play in short and long-term climate variability; and (4) the realization that addressing changes in our global climate requires understanding the interactions among various components of the earth system. The research currently being carried out represents an effort to address some of these issues by carrying out studies that combine radiation, ozone, seasonal thermal forcing and dynamics. Satellite and ground-based data that is already available is being used to construct basic states for our analytical and numerical models. Significant accomplishments from 1991-1992 are presented and include the following: ozone-dynamics interaction; (2) periodic local forcing and low frequency variability; and (3) steady forcing and low frequency variability
