The term mind mapping was devised by Tony Buzan for the representation of such things as ideas, notes and information, in radial tree diagrams â€” sometimes also called spider diagrams. These are now very widely used â€” try a web search on â€˜Buzanâ€™, â€˜mind mapâ€™ or â€˜concept mapâ€™.

â€˜The whole is more than the sum of its partsâ€™ is a good place to start thinking about systems. A car is more than its individual components. We can think of a football team as being more than a collection of individual players or a family being more than a group of people who share the same name.

Each of these examples â€“ the car, the football team and the family â€“ can be seen as systems. Individual parts of a system are connected together in some way for a purpose.

1. The diagram is a useful expositional or presentational device. When you are presenting an analysis or proposal, the diagram will enable you to describe (and distinguish between) the reasons for a change. It will enable you to do the same for the reasons why a change may be resisted.

2. The diagram will be an explicit prompt for exploring the restraining forces. The more a manager finds out about these, and the earlier, the better placed the manag

The results of the evaluation reflect the scores that are awarded to each option and the weightings that are attached to the different criteria. A change in one or the other (or in both) will lead to a change in the results. Accordingly, when you construct a matrix of this kind be sure to think hard about the scores and weightings. A matrix like this can be used in many ways, for example, when interviewing applicants as part of a selection process.

The scales that are used determine the look of the graph. For example, if the horizontal distance between â€˜Year 1â€™ and â€˜Year 6â€™ shown in Figure 2 were doubled, the line would be stretched to double its present length. If the horizontal distance were halved,

Arguments against the use of social marketing can be based on the following:

• Cost â€“ Social marketing programmes can cost considerable amounts of money. Criticisms of these expenditures are heightened as they are often financed by public money in times of resource constraints and therefore have a high opportunity cost. A related issue is that of the problems involved in assessing the success of these programmes. The long term nature of behavi

In a financial context, risk is a synonym for uncertainty â€“ the possibility that the actual outcome will differ from the mean expected outcome. It is therefore a neutral rather than a negative concept. Investors are risk-averse in the sense that they require more return for taking on more risk. Risk itself is measured by the standard deviation of actual returns around the mean expectation. In the real world, investment risk is created by a number of different factors that affect the certain

Our first question was: what is the mean expected total return for next year? We calculate this by taking each of the possible returns and weighting it by its relative probability. As our table is so simple and symmetrical, it is not difficult to see that the weighted mean return is 7% per annum.

Our second question was: what is the degree of risk or uncertainty in this mean figure? In other words, how widely dispersed are the possible outcomes around the mean expected outcome? The most

The person managing the project is not necessarily the best one to prepare the estimates, although they should be closely involved, both as a source of information and because they need a clear understanding of what the estimates mean and what the estimators assume about outputs, inputs and the transformation process. If there are others who have more experience or more knowledge about some of the areas of work, these people may be the best ones to make estimates for the project or parts of i

Scheduling is about deciding the time that each task will take to do and the sequence in which the tasks will be carried out. There are a number of approaches to estimating the time and effort (and, therefore, cost) required to complete a project. Some estimates may be based on past experience but, because each project is essentially unique, this alone may not be sufficient. A clearer picture can be obtained by measuring each task in terms of the content of the work, the effort required to ca

One of the most difficult aspects of planning a project is estimating how long it will take to complete each key stage. An estimate might be based on:

• the size of the tasks and the effort required to complete them;

• the number of days that are not available for working on the project;

• historical data from other projects, including the experience of colleagues.

Where a project has a fixed end-date (for

At the end of this unit you should be able to:

• develop plans with relevant people to achieve the project's goals;

• break work down into tasks and determine handover procedures;

• identify links and dependencies, and schedule to achieve deliverables;

• estimate and cost the human and physical resources required, and make plans to obtain the necessary resources;

• allocate roles with clear lines of responsibility and accountabil

Online bookshops and some of the major search engines offer â€˜Alertsâ€™ services. These work by allowing you to set up a profile once you have registered on their site, and when there are items meeting your criteria you receive an email. The good thing about alerts is that you donâ€™t have to do anything once you have set up your profile. The downside, particularly with alerts services from the search engines, is that given the extent to which internet traffic is on the increase whether new

By presentation, we mean, the way in which the information is communicated. You might want to ask yourself:

• Is the language clear and easy to understand?

• Is the information clearly laid out so that it is easy to read?

• Are the fonts large enough and clear?

• Are the colours effective? (e.g. white or yellow on black can be difficult to read)

• If there are graphics or photos, do they help

Before searching it is always a good idea to check what the source you have chosen covers to make sure it will unearth information that matches your search need (you will notice that all the resources weâ€™ve covered in this guide have short descriptions to enable you to decide which to use). Some of the decision makers, depending on the context of your search might be:

• Does it have full text?

• Does it cover the right subject?

At a basic level, a database is a collection of information which can be searched. It is a way of storing, indexing, organising and retrieving information. You may have created one yourself to keep track of your references â€“ or your friends' names and addresses. They are useful for finding articles on a topic, and can be used to search for many different types of information.

You may find some of the following databases useful for your topic. They contain different types of informatio
