Human beings have been executing projects from ancient times (Kwak, 2003). From relocating a tribe to constructing enormous buildings such as the pyramids, projects were a dominant element of history. Not long ago, those involved in projects understood that they needed methods and processes to help them manage these projects more efficiently. To meet this need, scientists and practitioners worked together to form a new concept which was called «project management». According to the PMBOK's definition "project management is the application of knowledge, skills, tools and techniques to project activities to meet project requirements". (A Guide to Project Management Body of Knowledge, 2004). There are many different views in the literature concerning the birth of project management. Maylor (2005) mentions that "project management in the way that we would understand it today did not exist until the 1950s" and Wideman (2001) tracks the first use of project management in the UK's Institution of Civil Engineers report on UK post war national development first published in 1944.
Since then, there have been a lot of changes. "The hard systems approach, which treated the project as a mechanical activity, has been shown to be flawed" (Maylor, 2005). The soft skills of project management are getting more attention because it is now clear that "the ability to apply these skills effectively throughout the life cycle of a project will enhance the success of a project exponentially" (Belzer). In spite of the perfect understanding of planning, scheduling and controlling, projects have still a high rate of failure. Belzer points out that "more often they fail because of a project manager's inability to communicate effectively, work within the organization's culture, motivate the project team, manage stakeholder expectations, understand the business objectives, solve problems effectively, and make clear and knowledgeable decisions". To address these problems in the 21st century, a project team needs to develop a series of soft skills such as "communication, team building, flexibility and creativity, leadership and the ability to manage stress and conflict". (Sukhoo et. al, 2005).
In addition, project management requires a stronger strategy orientation. "More than 80 per cent of all problems at the project level are caused by failures at a board level in firms to provide clear policy and priorities" (Maylor, 2001). The approach that Maylor suggests is very different from the traditional link between strategy and projects, as he proposes a "coherent, co-ordinated, focused, strategic competence in project management which eventually provides source of competitive advantage". This two-way methodology that relates organisational and project strategy is illustrated in figure 1. To better understand the project's strategy, there is also a need to analyse "the experiences from past activities, politics during the pre-project phases, parallel courses of events happening during project execution and ideas about the post-project future" (Mats Engwall, 2002).
Moreover, Maylor highlights a change in project's success criteria, from conformance to performance. In 1960s project managers seek to comply only with the documented specifications of the project, while current projects require real performance. In other words, the success criteria of the 21st century as indicated by Maylor have changed to as short time as possible, as cheaply as possible and towards a maximum customer delight. Other academics imply nowadays a much simpler view of success criteria which is focused only in keeping the client happy (Ferguson, 2005) in contrast with the 90s view of just finishing the project on time and on budget.
Changes in risk management are also one of the hot topics of project management in the new century. Ward (2003) propose the term «uncertainty management» and recommends that a "focus on «uncertainty» rather than risk could enhance project risk management". Adams has an interesting view of risk as he describes it as "a reflexive phenomenon - we respond to perceived probabilities and magnitudes, thereby altering them", a definition that differs from the traditional quantitive analysis of risk. Green broads even more the scope of risk management and includes the clients. He thinks that "the process of risk management only becomes meaningful through the active participation of the client's project stakeholders". In his point of view there is a new way of assessing risk management that "depends less upon probabilistic forecasting and more upon the need to maintain a viable political consistency within the client organisation".
The conventional theory of project management consists of a narrow focus on projects as unique and totally separated units of work. But current projects tend to be integrated smoothly in the general context of organizations in order to "develop the «management of project portfolios» and «programme management» which are more strategically orientated towards «doing the right projects»" (Winter & Smith, 2005).
It is common ground in the literature that the theory of project management needs more research. Koskela and Howell (2002) suggest that the theoretical base "has been implicit and it rests on a faulty understanding of the nature of work in projects, and deficient definitions of planning, execution and control". From their point of view, enrichment of project management with new methods and techniques cannot be done with any stable theoretical background. As a result, there is a trend of putting more effort in research and rethinking the way which «bodies of knowledge» is written so that complex projects' actions will be better documented.
As a conclusion, we could use the words of D.T. Jones (2005) who writes that "project management is no longer about managing the sequence of steps required to complete the project on time". He adds that "it is about systematically incorporating the voice of the customer, creating a disciplined way of prioritising effort and resolving trade-offs, working concurrently on all aspects of the projects in multi-functional teams".
