In Week 6, your project sponsor informed you t

  In Week 6, your project sponsor informed you that you have to deliver your project much sooner than anticipated. When you break the news to your team, they are not happy with the decision; they are concerned that the project will now fail. Using the information from the readings,  what can you do as a leader to reassure your project team that this is the right thing to do? What will you do to motivate them? Remember that they are professionals and that threats or traditional carrots may not work.

Preface to the eighth edition

Once, some time ago, my fellow day-release management students and I were invited to write a 5000-word assignment as part of our fist-year course work. Most of my colleagues spent many hours and late nights diligently researching this or that aspect of industry, marketing or economics for their material. Always keen to save time and effort, however, I chose to describe my own job. I think the result received an 'A-minus' but, more importantly, it seeded the first (1968) edition of this book. Now, after many subsequent years as a manager, I teach project management to MBA and MSc students. So a book originally written by a management student has been developed and improved through my management years and is now written very much with the needs of students in mind.

Project management is well supported in the literature. Excellent texts appear regularly in new editions that combine comprehensive theory with practical advice and case studies. Sometimes one or more of these admirable works are used alongside this book as recommended course texts. I am always pleased when students tell me that they prefer my book because they find it particularly approachable and easy to read. Of course, when the warm glow of satisfaction has subsided, I try to analyse the reasons and build on them. My abhorrence of unnecessary jargon and 'management speak' must be one reason. A writer must always seek to inform using plain language rather than set out to impress with words that compel the reader to have the book in one hand and a dictionary in other. So writing style is obviously important. But the text must also be easy to navigate. Readers, especially time-starved students on intensive courses, must be able to find or revisit any topic quickly. Some otherwise excellent books fall down in this respect. The chapters have to be organized in a logical sequence and, most important, everything must be comprehensively indexed.

My sequence of chapters has always been intended to track the logical progression of a project through its active life cycle from concept to closedown. There might be one or two anomalies in this respect because I have generally held back from significant restructuring that could cause inconvenience and rework for universities and other academic establishments where this book forms part of the recommended reading and where their course notes refer to particular chapters. It

u Project mnnagement

was necessary, however, to rearrange the chapters in Part VI to some extent to accommodate a new chapter on risk management. The total number of chapters has increased from 24 to 25.

Reproduction of very complex illustrations (large network diagrams, for instance) is not very practicable on a book page so, once again, I have reviewed every figure to ensure that it is designed and drawn for optimum clarity. The seventh edition introduced a few images captured from my computer screen that lost some definition in the printing process. All computer screen images have therefore been replaced in this edition by faithful simulations, prepared using a drawing program.

Text revisions are too numerous to list in detail, so I shall outline just a few of the more significant changes. These begin in Chapter 1, which has been extended to give more emphasis to the views of stakeholders beyond the project owner and project manager. The more mature view recognizes that the perceived success or failure of a project often depends on more than the three primary factors of time, money and quality.

Chapter 3 has been restructured to present its material in a more logical sequence.

The section on insurance that was previously placed in Chapter 6 has been updated (for which I am indebted once again to Robert Pow) and transferred to become part of Chapter 24, the completely new chapter dealing with project risk management. A new financial appraisal example, improved treatment of feasibility analysis and a short section on sensitivity analysis now strengthen the remainder of Chapter 6.

Some manual procedures, especially in the planning and resource scheduling chapters, have been removed because they are now well out of date and almost always performed using computers. While arrow networks can still play a valuable part in preliminary planning sessions and are therefore retained in Part 111, the last computer program known to me that could process these networks has recently been changed to a precedence-only capability. I have therefore updated all the examples in Part IV accordingly.

Following the format of previous editions, each part of this book ends with a short list of references and further reading. These have all been checked and, where appropriate, revised. For this eighth edition I have decided to add a general bibliography of books on project management.

Preface to the eighth edition xxi

Although an author might write with a particular readership in mind, he or she has no control over who buys and uses their work. Early editions of this book were intended for students and fellow industrial managers who might appreciate a practical and holistic guide to project management. Experience has since revealed a readership that extends to professional people with no apparent connection to industry or projects, demonstrating that project management has grown into a core management skill, to be practised in any organization and by any professional person undertaking a programme of change.

The nature and organization of

project management

The nature and purpose of project management

Project management as we know it today has evolved in order to plan, coordinate and control the complex and diverse activities of modern industrial, commercial and management change projects.

Clearly, man-made projects are not new; monuments surviving from the earliest civilizations testify to the incredible achievements of our forebears and still evoke our wonder and admiration. Modern projects, for all their technological sophistication, are not necessarily greater in scale than some of those early mammoth works. But economic pressures of the industrialized world, military defence needs, competition between rival companies, and greater regard for the value and well-being (and hence the employment costs) of working people have all led to the development of new ideas and techniques for managing projects.

All projects share one common characteristic – the projection of ideas and activities into new endeavours. The ever-present element of risk and uncertainty means that the events and tasks leading to completion can never be foretold with absolute accuracy. For some very complex or advanced projects even the possibility of successful completion might be in serious doubt.

The purpose of project management is to foresee or predict as many of the dangers and problems as possible and to plan, organize and control activities so that projects are completed as successfully as possible in spite of all the risks. This process starts before any resource is committed, and must continue until all work is finished. The primary aim of the project manager is for the final result to satisfy the project sponsor or purchaser, within the promised timescale and without using more money and other resources than those that were originally set aside or budgeted.

Much of the development in project management methods took place in the second half of the twentieth century, spurred by impatient project purchasers (who wanted their projects finished quickly so that their investments could be put to profitable use as soon as possible). Competition between nations for supremacy in weapons and defence systems played a significant role in the development of project management techniques, and the process has been accelerated by the widespread availability of powerful, reliable and cheap computers. Project

management is more effective when it makes appropriate use of these sophisticated techniques and facilities and, in this sense, is a highly specialized branch of management.

Planning and control must, of course, be exercised over all the activities and resources involved in a project. The project manager therefore needs to understand how all the various participants operate, and to appreciate (at least in outline) their particular skills, working methods, problems and weaknesses. This demands a fairly wide degree of general experience so that, in this practical sense, project management is akin to general management.

A software house once advertised its wares with the claim: 'If you can move a mouse you can manage a project'. Most people realize, however, that there is far more to project management than the application of a few computer programs, no matter how sophisticated those programs might be. Successful project management involves a whole framework of logical and progressive planning and decisions, perceptiveness, the liberal application of common sense, proper organization, effective commercial and financial management, painstaking attention to documentation, good communication skills and a clear grasp of proven and long-established principles of management and leadership.

Projects

The principal identifying characteristic of a project is its novelty. It is a step into the unknown, fraught with risk and uncertainty. No two projects are ever exactly alike: even a repeated project will differ from its predecessor in one or more commercial, administrative or physical aspects.

I find it convenient to classify projects under four main headings.

1 Civil engineering, construction, petrochemical, mining and quarrying

Projects in this category are those which spring to mind most readily whenever industrial projects are mentioned. One common feature is that the fulfilment phase must be conducted on a site that is exposed to the elements, and usually remote from the contractor's head office.

These projects incur special risks and problems of organization. They often require massive capital investment, and they deserve (but do not always get) rigorous management of progress, finance and quality.

For very large industrial projects the funding and resources needed are often too great for one contractor to risk or even find. The organization and communications are therefore likely to be complicated by the participation of many different specialists and contractors, with the main players possibly acting together as a consortium or joint venture company.

2 Manufacturing projects

Manufacturing projects aim to produce a piece of equipment or machinery, ship, aircraft, land vehicle or some other item of specially designed hardware. The finished product might be purpose-built for a single customer, or the project could be generated and funded from within a company for the design and development of a new product intended for subsequent manufacture and sale in quantity.
