This paper sets out to investigate the nature of projects conducted in fast changing environments. Examples and theory are used to illustrate the nature and challenges of this category. Suitable management approaches are identiﬁed under the following headings: Planning, Experimentation, Lifecycle, Controls, Culture, Communication, and Leadership style.

The dynamic project category. The paper closes with recommendations for further research. In this paper, control is taken to mean the mechanisms through which resources are managed to achieve objectives , and is diﬀerent to the PMBOK ‘technique’  which is strictly focused on bringing activities in line with a plan . The term dynamic is taken to mean characterised by constant change . In the project management context dynamism is taken to be a dimension of a project that represents the extent to which a project is inﬂuenced by changes in the environment in which it is conducted.
This paper argues that this is a non-binary dimension that applies in varying degrees to all projects, so strictly any given project is neither ‘dynamic’ nor ‘not dynamic’. All projects have some degree of dynamism, so the dimension is not dichotomic. Therefore, the ideas in this paper may be applied in varying degrees to any project as deemed appropriate. For the sake of simplicity though, for the remainder of this paper, a dynamic project is taken to be one that is necessarily subject to higher than normal levels of change due to the environment in which it is conducted.
The business environment is changing at an increasing pace [5–7]. Rothwell and Zegveld  went so far as to say we are in the midst of a technology explosion. They argued that 90% of our technical knowledge has been generated in the last 55 years, and that technical knowledge will continue to increase exponentially. Perrino and Tipping  reported ‘‘the pace of technology is accelerating, raising the stakes and risks for managing innovation, and requiring early warning and shorter response time”.
Change, in all forms of technology and business processes, can be regarded as increasingly pervasive and providing challenges even where
high technology is not a core business, such as in mining . Consider how the Australian Submarine project was challenged by developments in the IT industry between the 1980s design phase, and sea trials decades later . This paper will now investigate dynamic projects from a theoretical point of view. Gray and Larson  argued that
Pich, Loch and De Meyer  describe a type of project that encounters unknown unknowns and how it is best suited to what they called a ‘learning’ strategy which involves scanning, problem solving and ﬂexibility. They argue that this is distinct from projects conducted in well understood environments which are suited to ‘instructionism’, and distinct from ‘selectionism’ where the most fruitful initiative is chosen after a pool of trials. Turner and Cochran  espouse the ‘goals and methods matrix’ that describes four diﬀerent types of project according to how well deﬁned the methods and goals are.
Projects can have poorly deﬁned goals (‘ﬁre’) or poorly deﬁned methods (‘water’), or both (‘air’). Shenhar and Wideman  describe a type of project
that involves high levels of uncertainty, using technologies together for the ﬁrst time. They call these ‘high tech’ . They also describe a type of project that actually creates new technologies, called ‘super high tech’. Shenhar  describes how ‘low technology’ projects are typically performed in construction, production and utilities, and high technology projects in the computer, aerospace and electronics industries. He oﬀers building and bridge construction as examples of low technology projects.
The key diﬀerence to Shenhar is the level of development work involved, in that low technology projects have little, and
high technology projects have considerable levels and usually require prototyping. Shenhar and Wideman  argue that another key diﬀerence is the number of design cycles. In low technology projects they say there is typically only one cycle with a freeze before development, and with high technology there are at least two, typically three cycles.
Operational work Cioﬃ  suggests that ‘projects’ be placed on a spectrum of ‘newness’ from operational to project. The idea has been adapted in Fig. 1 to illustrate the sliding scale of unknowns that applies to projects. Unknowns in this sense refer to any aspect of the project, including the methods to achieve it, the objective, and the environment it has to operate in.
The guide to the project management body of knowledge (PMBOK)  describes ‘progressive elaboration’, where planning is developed in greater detail as the project progresses. Using progressive elaboration to ﬁll knowledge gaps, it might be possible to move a project to the left in Fig. 1, thereby achieving the objective in a more predictable fashion.
However, rapid changes in the environment, including tools and methods, and attempts to innovate, act to push the project to the right, increasing unknowns. The two forces of exploration and change act against each other continuously throughout the project. The challenge is
to conduct exploration at a greater rate than the emergence of environmental change. It is also important to ensure that the amount of change created by the exploration and implementation is not counterproductive overall. An example of Project A in Fig. 1 might be a production line where there only variable is the colour required.
The intention here is to review literature to provide a broad overview of approaches that might be used to better deal with dynamic environments. Approaches were broken
down as follows:
