Costs: Short Run and Long Run


In the short run costs are fixed; in the long run they become variable. This is the fundamental difference between long run and short run. The distinction is a matter of degree. The longer the run contemplated, the greater the range of costs regarded as variable rather than fixed.

Consider a manufacturing firm. Toward the variable cost end are the expenses of inputs like electric power, supplies of material, and ordinary labor services; toward the fixed end are costs associated of supplies or breakdown of machinery calls for a very short, say an hour’s, reduction of output. Some electric power would be saved in the slowdown, and there would be reduced usage of materials, but little else could or would be changed. If output were to be cut back over a period as long as a day, some labor might also be laid off. Over a period like a month a large function of the labor force might be furloughed (their wages would become a variable cost), and perhaps some leased equipment like trucks would be dispensed with. Finally, for a permanent reduction in output the firm will sell off machinery and scale down its real-estate commitments.

Bases for Market Segmentation


Two broad types of variables are commonly used for market segmentation. Socioeconomic characteristics of consumers, such as gender, age, occupation, income, family life cycle, education, and geographic location make up one type. The other type consists of behavioral variables, including benefits sought from products and services, usage behavior, lifestyle, and attitudes. For industrial buyers, socioeconomic characteristics may include company size and location, and industry or customers served. Behavioral variables may include purchasing objectives and practices as well as product and service benefits. The appropriateness of any one or combination of variables in a specific situation will depend on whether or not a variable relates to purchasing, use, or consumption behavior and responsiveness to marketing programs.

The choice of variables to use to segment a market often depends on insights into buyer behavior, provided by creative research. Even people with similar usage needs often have differing lifestyles representing various value sets. For example, some people have an active lifestyles in which sports and fitness play an important role, while for others arts, fashion and trends may be very important.

Erosion Measures


Erosion measures refer to natural remnants of some individual’s or group’s activity that has selectively worn down certain objects. For example, if you are working in a nursing home, you might determine what the most popular activity in that home is by observing where the rugs are most worn. It might be in front of the television set or in front of the windows where people spend time looking out at the street. This could give you a possible measure for evaluating changes in the group’s activities.

 Other erosion measures might include decay and breakage. Active or aggressive physical activity can be inferred from the number of broken items (for example, windows) in a school or ward. The frequency of repair, replacement, or cleaning of certain objects in a setting may be used as an indicator of frequency of usage.

 When using erosion measures be sure that unrelated factors are not the reasons for observed changes. For example, a new junior’s zeal in cleaning may be responsible for changes in the patterns of use as detected by wear and tear on the floor. Similarly, it would help to know the amount of ordinary wear and tear on objects so that any excessive erosion or wear and tear can be related to target behaviors with more assurance.

 The second category of physical traces is accretion measures. These are objects deposited by clients in a given setting or the ordinary debris left by client interaction with or consumption of material. Thus, many of the behavior produces described earlier could be considered as accretion measures. Accretion measures also often focus on analysis of remains or even rubbish.

 Reliability and validity concerns are as important when using physical traces as they are with other measures, and these concerns are especially important when physical traces are being used to make inferences about behaviors.

Project Management


A project is any group of activities with a common goal, for which we try to control costs, resource usage, completion time, and quality of the output. However, large (one-time or multiple) projects in the range of millions to hundreds of millions of dollars are more common and undoubtedly have a larger total economic impact. Examples include new plants, schools, office buildings, research programs, some types of electronic research and development, bridges, and highways. Projects in the thousands to one million dollar range are even more numerous and include building houses, remodeling offices, modernizing wiring and plumbing, establishing a small PC cluster, and so on. Small and very small projects are too numerous to try to catalog. For example, getting to work in the morning can be considered a project, with such activities as shower, brush teeth, put on shoes, dry hair, and so on.

 Project management is a broad multi-level activity which involves strategic planning, middle- and short-term planning, scheduling, and control. We will first give a broad introduction to project management at all levels from strategic planning to control. Next we present the foundation of project scheduling without considering resource constraints. Then we consider the case of project scheduling with resource constraints from several points of view. Finally we discuss broader issues surrounding scheduling such as project design and strategic project control.

 Most of the formal work in project management has focused on large one-time projects. Project management tends to be a very involved process, requiring the careful coordination of experts in a number of areas. It is important that the individual parts of the process be carefully organized. It requires developing and manipulating a great deal of data and reports. The scheduling and control portion of project management have benefited greatly from the PC revolution.
