Chapter 7 Managing risk and quality
Learning objectives • discuss the importance of risk in a project and how it can be managed • explain the processes of risk planning, risk assessment and risk control • describe tools used in risk management and how to use them effectively • explain the process of contingency planning in project management
Learning objectives (continued) • discuss the importance of quality to project management • explain three important quality management processes • outline key contributions to quality management by Deming, Juran and Crosby • explain how to determine the total cost of quality • describe simple tools used in statistical process control and how to use them effectively
Risk and risk management • A project risk is often described as: • any event with an undesirable outcome for the project that may happen sometime in the future. • The 2000 edition of the Guide to the Project Management Body of Knowledge (PMI, 2000) states that a project risk is: • an uncertain event or condition that, if it occurs, has a positive or negative effect on a project outcome.
The two categories of risk • Speculative risk - meaning a chance of a loss or chance of a profit • Pure risk - meaning only a chance of a loss
The risk management plan will take account of risks arising from 3 principal sources: • Factors under project control • Factors in the wider external environment which are only controllable by decision makers elsewhere • Factors that are essentially uncontrollable
Project risks are characterised by the fact that: • they are usually at least partially unknown • they change with time • they are manageable, in the sense that action may be taken to change their impact • they exist only in the future tense – there are no past risks, only actual occurrences • they exist in all projects.
Risk management is about balancing the harmful effects of risk against potential project benefits.
Risk management can be divided into two types of activities: • Risk assessment activities • Risk control activities
Risk assessment • The following activities are associated with risk assessment: • Risk identification • Risk analysis • Risk prioritisation
Identification of risks • The process of risk identification should: • examine all areas of a project in a systematic manner • be proactive rather than reactive • use information from all available sources. For example: • previous lessons learned files and other historical information about the project and its context • all planning outputs to date including work breakdown structures, schedule and cost plans • the project charter, industry-wide and organisation-wide risk checklists • feasibility reports
Risk analysis • About establishing the probability of occurrence and the impact of occurrence of all identified project risks • Once these two variables have been determined, the risk exposure of the project to each risk can be calculated using the equation: • Risk exposure = probability of risk x impact of risk
Risk prioritisation • This method should consider the following three factors: • Probability of the risk occurring • Impact of the risk – which can be broken down further, for example, into: • impact on schedule • impact on cost • impact on performance • Cost and resources required to mitigate the risk
Tolerability of risk (ToR) • A ToR framework defines three bands of risk: intolerable, tolerable and negligible
Risk response planning • Purpose is simply to bring organised, purposeful thought to the subject of: • eliminating risk wherever possible • isolating and minimising risk • developing alternative courses of action • establishing time and money reserves to cover risks that cannot be avoided • The output of this process is a risk response plan • There are six types of response to risk: • Avoidance 4. Transfer • Mitigation 5. Absorption or pooling • Acceptance 6. Knowledge and research
Contingency planning - if all else fails… • A contingency plan should identify: • alternative resources and/or processes for completing mission critical tasks (for example using manual labour for a task that has been automated) • resources needed to launch and maintain such processes • lead time for the substitute processes to become functional • trigger point that causes a contingency plan to be activated
Quality management About managing the quality of the products, services and processes associated with a project
International Organisation for Standardisation (ISO) • The ISO standards specify the requirements which determine what elements a quality system has to contain - but do not specify how a specific company should implement them • The basic approach to quality management used in a project should be compatible with ISO and with approaches to quality management such as those recommended by Deming, Juran and Crosby

Crosby • Best known in relation to concepts of ‘do it right first time’ and ‘zero defects’ • Based on four absolutes of quality management: • Quality is defined as conformance to requirements, not as ‘goodness’ or ‘elegance’ • The system for causing quality is prevention, not appraisal • The performance standard must be zero defects, not ‘that’s close enough’ • The measurement of quality is the price of nonconformance, not indices
The cost of quality • There are three elements to the cost of quality: • Prevention costs • Appraisal costs • Failure costs • The total cost of quality is the sum of all three. Total cost = Failure + Appraisal + Prevention of quality costs costs costs
Quality control tools • Are helpful to identify, quantify and then reduce the costs of quality • Primary aim is to assure satisfactory quality in all processes • Designed to be easy-to-use tools for quality control, which can be used by anyone involved in a project
