Where should management effort be directed? In controlling costs and ensuring proper engineering in live projects? - yes, of course, but true cost control comes by understanding, eliminating and minimising risk prior to a business committing any funds. This course studies the stages required for practical financial and business appraisals of projects and capital expenditure. This course has two primary objectives: To impart the knowledge and skills required to ensure as risk-free as possible expenditure of that scarce resource, cash - the investors', governments' or shareholders' money must not be squandered To improve the quality of the appraisal process in the widest sense - demonstrating how the process of project and capital expenditure appraisal can be used to dramatically improve cost control and deliver as risk-free as possible expenditure As a result of the course, participants will be able to: Understand the economics of appraisal Be in control of their projects from the start Understand the economics of their projects - and devise the most appropriate mode Carry out sensitivity analysis and identify risk Improve their methods of appraisal and approach Focus on the risk areas and take out risk and control costs before they over-run The benefits of attending this course will be demonstrable from day one. Thorough appraisals and risk assessment follow through to success in project management and detailed cost control and project management. 1 Introduction Why appraise? Taking risk out of investment The short- and long-term results of not appraising business expenditure 2 Developing an appraisal process The process - overall and stage-by-stage objectives Understand business and technical risks Manage resources and time Do you invest enough time and effort at this stage? Take out the risks - control costs before you are committed to contracts and action Checklists 3 Appraisal arithmetic Review of the arithmetic of appraisalThe time value of moneyThe effects of different interest or required ratesThe effects of inflation (or deflation) in prices and costs Understanding the economics of appraisal is essential 4 Appraisal measures Meaning and use of appraisal measures Identifying the most appropriate measures for your particular business Payback Discounted cash flow measures - NPV and IRR Other measures - FW, AW, Profitability Index The meaning of the measures and their application in practice 5 Cost benefit analysis The effect on decision-making of more intangible benefits Cost benefit analysis Ensuring costs are genuine Measuring intangible benefits Environmental issues Consideration of intangible benefits in the appraisal decision-making process 6 Developing appropriate models Developing models - examples of spreadsheet models and measures for many different situations Modelling investment opportunities - summarising outcomes Sensitivity analysis - identifying, quantifying and taking out risk 7 Developing an appraisal process The process - managing risk from the outset Using the process in risk management, negotiating and project management Take out risk by thoroughly knowing your project - developing your own process
