Balance Sheet

Balance Sheet Management

The management of all resources (particularly assets) to ensure the desired delivery outputs, especially where such delivery impacts the long term, sustained "wealth" of the organization (through an increase in assets or equity and/or a reduction of liabilities). Source: A4


An adopted measure of performance against which the relative performance of other similar, external systems, procedures or entities can be compared. Source: A1

A point of reference from which quality or excellence is measured. Source: M1


A systematic measurement of organizational performance over time and/or against other equivalent organizations or industry norms. Benchmarking comes in two types:

Output: here the measuring stick is what the organization delivers - lane miles of road recapped in a year, etc. It often is efficiency oriented, measuring the cost per unit of output.

Best Practice: An ongoing systematic process to search for and introduce international best practice into an organization, in such a way that all parts of the organization understand and achieve their full potential. The search may be for products, services, business practices and processes of competitors or those organizations recognized as leaders, in the industry or in the specific processes chosen. The benchmark used here is the range and level of best practices actually incorporated into the organization. Source: B2

Benefit-Cost Analysis (BCA)

A technique for the evaluation of projects where all benefits and costs, both direct and indirect, community-wide as well as organizational, are considered. Where possible, all benefits and costs should be quantified in financial terms. Where this is not possible the benefits and costs should be quantified in non-financial terms or described so as to identify the impact of the benefit or cost. Source: T2

Benefit-Cost Ratio (BCR)

The sum of the present values of all benefits including residual value if any, over the facility life cycle, divided by the sum of the present values of all costs. Simply, it is discounted benefits divided by discounted costs. The ratio needs to be 1 or greater for the project to proceed (meaning that the benefits exceed the costs). However, it is not an ideal decision support tool as the ratio may vary by treating costs as negative benefits, or vice versa. Source: T2

Best Appropriate Practice (BAP)

"Best Appropriate Practice" for an organization is that goal of excellence in Total Asset Management Planning the organization can realistically hope to achieve over time, bearing in mind existing and ongoing organizational resource constraints. This target differs from the concept of "world's best practice' in that "Best Appropriate Practice" is defined by analysis of costs and benefits achievable to the organization given its operating context.

Best Practice

The co-operative way in which firms and their employees undertake business activities in all key processes; leadership, planning, customers, suppliers, community relations, production and supply of products and services, and the use of benchmarking.

An outline of the priorities and plans for the coming year, expressed in terms of financial information and non-financial performance information. Governmental budgets serve three purposes: 1) to set public policy, 2) to act as a legislative control on taxing and spending by the executive branch, and 3) to serve as a financial planning tool. In most public sector organizations, budget appropriations have the force of law in governing the raising of revenues and the authorization to spend. Source: S3 (modified)
