Project
management is the discipline of planning, organizing, securing, managing,
leading, and controlling resources to achieve specific goals. A project is a
temporary endeavor with a defined beginning and end (usually time-constrained,
and often constrained by funding or deliverables), undertaken to meet unique
goals and objectives, typically to bring about beneficial change or added
value. The temporary nature of projects stands in contrast with business as
usual (or operations), which are repetitive, permanent, or semi-permanent
functional activities to produce products or services. In practice, the
management of these two systems is often quite different, and as such requires
the development of distinct technical skills and management strategies.
The
primary challenge of project management is to achieve all of the project goals
and objectives while honoring the preconceived constraints. The primary
constraints are scope, time, quality and budget. The secondary and more
ambitious challenge is to optimize the allocation of necessary inputs and
integrate them to meet pre-defined objectives.
History
Until
1900 civil engineering projects were generally managed by creative architects,
engineers, and master builders themselves, for example Vitruvius (first century
BC), Christopher Wren (1632–1723), Thomas Telford (1757–1834) and Isambard
Kingdom Brunel (1806–1859). It was in the 1950s that organizations started to
systematically apply project management tools and techniques to complex
engineering projects.
Henry
Gantt (1861–1919), the father of planning and control techniques
As
a discipline, project management developed from several fields of application
including civil construction, engineering, and heavy defense activity. Two
forefathers of project management are Henry Gantt, called the father of
planning and control techniques, who is famous for his use of the Gantt chart
as a project management tool (alternatively Harmonogram first proposed by Karol
Adamiecki; and Henri Fayol for his creation of the five management functions
that form the foundation of the body of knowledge associated with project and program
management. Both Gantt and Fayol were students of Frederick Winslow Taylor's
theories of scientific management. His work is the forerunner to modern project
management tools including work breakdown structure (WBS) and resource
allocation.

The
1950s marked the beginning of the modern project management era where core
engineering fields come together to work as one. Project management became
recognized as a distinct discipline arising from the management discipline with
engineering model. In the United States, prior to the 1950s, projects were
managed on an ad-hoc basis, using mostly Gantt charts and informal techniques
and tools. At that time, two mathematical project-scheduling models were
developed. The "Critical Path Method" (CPM) was developed as a joint
venture between DuPont Corporation and Remington Rand Corporation for managing
plant maintenance projects. And the "Program Evaluation and Review
Technique" or PERT, was developed by Booz Allen Hamilton as part of the
United States Navy's (in conjunction with the Lockheed Corporation) Polaris
missile submarine program; These mathematical techniques quickly spread into
many private enterprises.
At
the same time, as project-scheduling models were being developed, technology
for project cost estimating, cost management, and engineering economics was
evolving, with pioneering work by Hans Lang and others. In 1956, the American
Association of Cost Engineers (now AACE International; the Association for the
Advancement of Cost Engineering) was formed by early practitioners of project
management and the associated specialties of planning and scheduling, cost
estimating, and cost/schedule control (project control). AACE continued its
pioneering work and in 2006 released the first integrated process for portfolio,
program and project management (Total Cost Management Framework).
The
International Project Management Association (IPMA) was founded in Europe in
1967, as a federation of several national project management associations. IPMA
maintains its federal structure today and now includes member associations on
every continent except Antarctica. IPMA offers a Four Level Certification
program based on the IPMA Competence Baseline (ICB). The ICB covers technical,
contextual, and behavioral competencies.
In
1969, the Project Management Institute (PMI) was formed in the USA.PMI
publishes A Guide to the Project Management Body of Knowledge (PMBOK Guide),
which describes project management practices that are common to "most
projects, most of the time." PMI also offers multiple certifications.
Approaches
There
are a number of approaches to managing project activities including lean,
iterative, incremental, and phased approaches.
Regardless
of the methodology employed, careful consideration must be given to the overall
project objectives, timeline, and cost, as well as the roles and
responsibilities of all participants and stakeholders.
![]() |
| Typical development phases of an engineering project |
The
traditional approach
A
traditional phased approach identifies a sequence of steps to be completed. In
the "traditional approach", five developmental components of a
project can be distinguished (four stages plus control):
Typical
development phases of an engineering project
1. initiation
2. planning and design
3. execution and construction
4. monitoring and controlling systems
5. completion
Not
all projects will have every stage, as projects can be terminated before they
reach completion. Some projects do not follow a structured planning and/or
monitoring process. And some projects will go through steps 2, 3 and 4 multiple
times.
Many
industries use variations of these project stages. For example, when working on
a brick-and-mortar design and construction, projects will typically progress
through stages like pre-planning, conceptual design, schematic design, design
development, construction drawings (or contract documents), and construction
administration. In software development, this approach is often known as the
waterfall model, i.e., one series of tasks after another in linear sequence. In
software development many organizations have adapted the Rational Unified
Process (RUP) to fit this methodology, although RUP does not require or
explicitly recommend this practice. Waterfall development works well for small,
well defined projects, but often fails in larger projects of undefined and
ambiguous nature. The Cone of Uncertainty explains some of this as the planning
made on the initial phase of the project suffers from a high degree of
uncertainty. This becomes especially true as software development is often the realization
of a new or novel product. In projects where requirements have not been
finalized and can change, requirements management is used to develop an
accurate and complete definition of the behavior of software that can serve as
the basis for software development. While the terms may differ from industry to
industry, the actual stages typically follow common steps to problem
solving"defining the problem, weighing options, choosing a path,
implementation and evaluation."
PRINCE2
![]() |
| The PRINCE2 process model |
PRINCE2
is a structured approach to project management, released in 1996 as a generic
project management method. It combined the original PROMPT methodology (which
evolved into the PRINCE methodology) with IBM's MITP (managing the
implementation of the total project) methodology. PRINCE2 provides a method for
managing projects within a clearly defined framework. PRINCE2 describes
procedures to coordinate people and activities in a project, how to design and
supervise the project, and what to do if the project has to be adjusted if it
does not develop as planned.
In
the method, each process is specified with its key inputs and outputs and with
specific goals and activities to be carried out. This allows for automatic
control of any deviations from the plan. Divided into manageable stages, the
method enables an efficient control of resources. On the basis of close
monitoring, the project can be carried out in a controlled and organized way.
PRINCE2
provides a common language for all participants in the project. The various
management roles and responsibilities involved in a project are fully described
and are adaptable to suit the complexity of the project and skills of the
organization.
PRiSM
(Projects integrating Sustainable Methods)
PRiSM
is a structured project management method developed to align organizational
sustainability initiatives with project delivery. By design, PRiSM is a
repeatable, practical and proactive methodology that ensures project success
while decreasing an organization's negative environmental impact.
The
methodology encompasses the management, control and organization of a project
with consideration and emphasis beyond the project life-cycle and on the five
aspects of sustainability. PRiSM is also used to refer to the training and
accreditation of authorized practitioners of the methodology who must undertake
accredited qualifications based on competency to obtain the GPM certification.
Critical
chain project management
Critical
chain project management (CCPM) is a method of planning and managing project
execution designed to deal with uncertainties inherent in managing projects,
while taking into consideration limited availability of resources (physical,
human skills, as well as management & support capacity) needed to execute
projects.
CCPM
is an application of the Theory of Constraints (TOC) to projects. The goal is
to increase the flow of projects in an organization (throughput). Applying the
first three of the five focusing steps of TOC, the system constraint for all
projects is identified as are the resources. To exploit the constraint, tasks
on the critical chain are given priority over all other activities. Finally,
projects are planned and managed to ensure that the resources are ready when
the critical chain tasks must start, subordinating all other resources to the
critical chain.
The
project plan should typically undergo resource leveling, and the longest
sequence of resource-constrained tasks should be identified as the critical
chain. In some cases, such as managing contracted sub-projects, it is advisable
to use a simplified approach without resource leveling.
In
multi-project environments, resource leveling should be performed across
projects. However, it is often enough to identify (or simply select) a single
"drum". The drum can be a resource that acts as a constraint across
projects, which are staggered based on the availability of that single
resource.
One
can also use a "virtual drum" by selecting a task or group of tasks
(typically integration points) and limiting the number of projects in execution
at that stage.
Event
chain methodology
Event
chain methodology is another method that complements critical path method and
critical chain project management methodologies.
Event
chain methodology is an uncertainty modeling and schedule network analysis
technique that is focused on identifying and managing events and event chains
that affect project schedules. Event chain methodology helps to mitigate the
negative impact of psychological heuristics and biases, as well as to allow for
easy modeling of uncertainties in the project schedules. Event chain
methodology is based on the following principles.
Probabilistic
moment of risk: An activity (task) in most real-life processes is not a
continuous uniform process. Tasks are affected by external events, which can
occur at some point in the middle of the task.
Event
chains: Events can cause other events, which will create event chains. These
event chains can significantly affect the course of the project. Quantitative
analysis is used to determine a cumulative effect of these event chains on the
project schedule.
Critical
events or event chains: The single events or the event chains that have the
most potential to affect the projects are the “critical events” or “critical
chains of events.” They can be determined by the analysis.
Project
tracking with events: Even if a project is partially completed and data about
the project duration, cost, and events occurred is available, it is still
possible to refine information about future potential events and helps to
forecast future project performance.
Event
chain visualization: Events and event chains can be visualized using event
chain diagrams on a Gantt chart.
Process-based
management
Also
furthering the concept of project control is the incorporation of process-based
management. This area has been driven by the use of Maturity models such as the
CMMI (capability maturity model integration; see this example of a predecessor)
and ISO/IEC15504 (SPICE – software process improvement and capability
estimation).
Agile
project management
![]() |
| The iteration cycle in Agile project management |
Agile
project management approaches based on the principles of human interaction
management are founded on a process view of human collaboration. It is
"most typically used in software, website, technology, creative and
marketing industries." This contrasts sharply with the traditional
approach. In the agile software development or flexible product development
approach, the project is seen as a series of relatively small tasks conceived
and executed as the situation demands in an adaptive manner, rather than as a
completely pre-planned process.
Lean
project management
Lean
project management combines principles from lean manufacturing with agile
project management, to focus on delivering more value with less waste.
Extreme
project management
In
critical studies of project management it has been noted that several PERT
based models are not well suited for the multi-project company environment of
today.[citation needed] Most of them are aimed at very large-scale, one-time,
non-routine projects, and currently all kinds of management are expressed in
terms of projects.
![]() |
| Planning and feedback loops in Extreme programming (XP) with the time frames of the multiple loops |
Using
complex models for "projects" (or rather "tasks") spanning
a few weeks has been proven to cause unnecessary costs and low maneuverability
in several cases[citation needed]. Instead, project management experts try to
identify different "lightweight" models, such as Extreme Programming
and Scrum.
The
generalization of Extreme Programming to other kinds of projects is extreme
project management, which may be used in combination with the process modeling
and management principles of human interaction management.
Benefits
realisation management
Benefits
realization management (BRM) enhances normal project management techniques
through a focus on agreeing what outcomes should change (the benefits) during
the project, and then measuring to see if that is happening to help keep a
project on track. This can help to reduce the risk of a completed project being
a failure as instead of attempting to deliver agreed requirements the aim is to
deliver the benefit of those requirements.
An
example of delivering a project to requirements could be agreeing on a project
to deliver a computer system to process staff data with the requirement to
manage payroll, holiday and staff personnel records. Under BRM the agreement
would be to use the suppliers suggested staff data system to see an agreed
reduction in staff hours processing and maintaining staff data (benefit reduce
HR headcount).
Processes
![]() |
| The project development stages |
Traditionally,
project management includes a number of elements: four to five process groups,
and a control system. Regardless of the methodology or terminology used, the
same basic project management processes will be used. Major process groups
generally include:
1. initiation
2. planning or development
3. production or execution
4. monitoring and controlling
5. closing
In
project environments with a significant exploratory element (e.g., research and
development), these stages may be supplemented with decision points (go/no go
decisions) at which the project's continuation is debated and decided. An
example is the Phase–gate model.
Initiating
![]() |
| Initiating process group processes |
The
initiating processes determine the nature and scope of the project. If this
stage is not performed well, it is unlikely that the project will be successful
in meeting the business’ needs. The key project controls needed here are an
understanding of the business environment and making sure that all necessary
controls are incorporated into the project. Any deficiencies should be reported
and a recommendation should be made to fix them.
The
initiating stage should include a plan that encompasses the following areas:
* analyzing the business needs/requirements in
measurable goals
* reviewing of the current operations
* financial analysis of the costs and benefits
including a budget
* stakeholder analysis, including users, and
support personnel for the project
* project charter including costs, tasks,
deliverables, and schedule
Planning
and design
After
the initiation stage, the project is planned to an appropriate level of detail
(see example of a flow-chart). The main purpose is to plan time, cost and
resources adequately to estimate the work needed and to effectively manage risk
during project execution. As with the Initiation process group, a failure to
adequately plan greatly reduces the project's chances of successfully
accomplishing its goals.
Project
planning generally consists of
* determining how to plan (e.g. by level of
detail or rolling wave);
* developing the scope statement;
* selecting the planning team;
* identifying deliverables and creating the
work breakdown structure;
* identifying the activities needed to complete
those deliverables and networking the activities in their logical sequence;
* estimating the resource requirements for the
activities;
* estimating time and cost for activities;
* developing the schedule;
* developing the budget;
* risk planning;
* gaining formal approval to begin work.
Additional
processes, such as planning for communications and for scope management,
identifying roles and responsibilities, determining what to purchase for the
project and holding a kick-off meeting are also generally advisable.
For
new product development projects, conceptual design of the operation of the
final product may be performed concurrent with the project planning activities,
and may help to inform the planning team when identifying deliverables and
planning activities.
Executing
![]() |
| Executing process group processes |
Executing
consists of the processes used to complete the work defined in the project plan
to accomplish the project's requirements. Execution process involves
coordinating people and resources, as well as integrating and performing the
activities of the project in accordance with the project management plan. The
deliverables are produced as outputs from the processes performed as defined in
the project management plan and other frameworks that might be applicable to
the type of project at hand.
Monitoring
and controlling
![]() |
| Monitoring and controlling process group processes |
Monitoring
and controlling consists of those processes performed to observe project
execution so that potential problems can be identified in a timely manner and
corrective action can be taken, when necessary, to control the execution of the
project. The key benefit is that project performance is observed and measured
regularly to identify variances from the project management plan.
Monitoring
and controlling includes:
* Measuring the ongoing project activities
('where we are');
* Monitoring the project variables (cost,
effort, scope, etc.) against the project management plan and the project
performance baseline (where we should be);
* Identify corrective actions to address issues
and risks properly (How can we get on track again);
* Influencing the factors that could circumvent
integrated change control so only approved changes are implemented.
In
multi-phase projects, the monitoring and control process also provides feedback
between project phases, in order to implement corrective or preventive actions
to bring the project into compliance with the project management plan.
Project
maintenance is an ongoing process, and it includes:
* Continuing support of end-users
* Correction of errors
* Updates of the software over time
Monitoring
and controlling cycle
![]() |
Monitoring
& controlling cycle
|
In
this stage, auditors should pay attention to how effectively and quickly user
problems are resolved.
Over
the course of any construction project, the work scope may change. Change is a
normal and expected part of the construction process. Changes can be the result
of necessary design modifications, differing site conditions, material
availability, contractor-requested changes, value engineering and impacts from
third parties, to name a few. Beyond executing the change in the field, the
change normally needs to be documented to show what was actually constructed.
This is referred to as change management. Hence, the owner usually requires a
final record to show all changes or, more specifically, any change that
modifies the tangible portions of the finished work. The record is made on the
contract documents – usually, but not necessarily limited to, the design
drawings. The end product of this effort is what the industry terms as-built
drawings, or more simply, “as built.” The requirement for providing them is a
norm in construction contracts.
When
changes are introduced to the project, the viability of the project has to be
re-assessed. It is important not to lose sight of the initial goals and targets
of the projects. When the changes accumulate, the forecasted result may not
justify the original proposed investment in the project.
Closing
![]() |
| Closing process group processes. |
Closing includes the formal acceptance of the project and the ending thereof. Administrative activities include the archiving of the files and documenting lessons learned.
This phase consists of:
* Project close: Finalize all activities across
all of the process groups to formally close the project or a project phase
* Contract closure: Complete and settle each
contract (including the resolution of any open items) and close each contract
applicable to the project or project phase.
Project
controlling and project control systems
Project
controlling should be established as an independent function in project
management. It implements verification and controlling function during the
processing of a project in order to reinforce the defined performance and
formal goals. The tasks of project controlling are also:
* the creation of infrastructure for the supply
of the right information and its update
* the establishment of a way to communicate
disparities of project parameters
* the development of project information
technology based on an intranet or the determination of a project key
performance index system (KPI)
* divergence analyses and generation of
proposals for potential project regulations
* the establishment of methods to accomplish an
appropriate the project structure, project workflow organization, project
control and governance
* creation of transparency among the project
parameters
Fulfillment
and implementation of these tasks can be achieved by applying specific methods
and instruments of project controlling. The following methods of project
controlling can be applied:
* investment analysis
* cost–benefit analyses
* value benefit Analysis
* expert surveys
* simulation calculations
* risk-profile analyses
* surcharge calculations
* milestone trend analysis
* cost trend analysis
* target/actual-comparison
Project
control is that element of a project that keeps it on-track, on-time and within
budget. Project control begins early in the project with planning and ends late
in the project with post-implementation review, having a thorough involvement
of each step in the process. Each project should be assessed for the
appropriate level of control needed: too much control is too time consuming,
too little control is very risky. If project control is not implemented
correctly, the cost to the business should be clarified in terms of errors,
fixes, and additional audit fees.
Control
systems are needed for cost, risk, quality, communication, time, change,
procurement, and human resources. In addition, auditors should consider how
important the projects are to the financial statements, how reliant the
stakeholders are on controls, and how many controls exist. Auditors should
review the development process and procedures for how they are implemented. The
process of development and the quality of the final product may also be
assessed if needed or requested. A business may want the auditing firm to be
involved throughout the process to catch problems earlier on so that they can
be fixed more easily. An auditor can serve as a controls consultant as part of
the development team or as an independent auditor as part of an audit.
Businesses
sometimes use formal systems development processes. These help assure that
systems are developed successfully. A formal process is more effective in
creating strong controls, and auditors should review this process to confirm
that it is well designed and is followed in practice. A good formal systems
development plan outlines:
* A strategy to align development with the
organization’s broader objectives
* Standards for new systems
* Project management policies for timing and
budgeting
* Procedures describing the process
* Evaluation of quality of change
Topics
Project
managers
A
project manager is a professional in the field of project management. Project
managers can have the responsibility of the planning, execution, and closing of
any project, typically relating to construction industry, engineering,
architecture, computing, and telecommunications. Many other fields in the
production engineering and design engineering and heavy industrial have project
managers.
A
project manager is the person accountable for accomplishing the stated project
objectives. Key project management responsibilities include creating clear and
attainable project objectives, building the project requirements, and managing
the triple constraint for projects, which is cost, time, and scope.
A
project manager is often a client representative and has to determine and
implement the exact needs of the client, based on knowledge of the firm they
are representing. The ability to adapt to the various internal procedures of
the contracting party, and to form close links with the nominated
representatives, is essential in ensuring that the key issues of cost, time,
quality and above all, client satisfaction, can be realized.
Project
management triangle
The
project management triangle
Like
any human undertaking, projects need to be performed and delivered under
certain constraints. Traditionally, these constraints have been listed as
"scope," "time," and "cost". These are also
referred to as the "project management triangle", where each side
represents a constraint. One side of the triangle cannot be changed without
affecting the others. A further refinement of the constraints separates product
"quality" or "performance" from scope, and turns quality
into a fourth constraint.
The
time constraint refers to the amount of time available to complete a project.
The cost constraint refers to the budgeted amount available for the project.
The scope constraint refers to what must be done to produce the project's end
result. These three constraints are often competing constraints: increased
scope typically means increased time and increased cost, a tight time
constraint could mean increased costs and reduced scope, and a tight budget
could mean increased time and reduced scope.
The
discipline of project management is about providing the tools and techniques
that enable the project team (not just the project manager) to organize their
work to meet these constraints.
Work
breakdown structure
The
work breakdown structure (WBS) is a tree structure that shows a subdivision of
effort required to achieve an objective for example a program, project, and
contract. The WBS may be hardware-, product-, service-, or process-oriented
(see an example in a NASA reporting structure (2001)).
A
WBS(work break down) can be developed by starting with the end objective and
successively subdividing it into manageable components in terms of size,
duration, and responsibility (e.g., systems, subsystems, components, tasks,
sub-tasks, and work packages), which include all steps necessary to achieve the
objective.
The
work breakdown structure provides a common framework for the natural
development of the overall planning and control of a contract and is the basis
for dividing work into definable increments from which the statement of work
can be developed and technical, schedule, cost, and labor hour reporting can be
established.
Project
management framework
The
Program (Investment) life cycle integrates the project management and system
development life cycles with the activities directly associated with system
deployment and operation. By design, system operation management and related
activities occur after the project is complete and are not documented within
this guide (see an example of an IT project management framework).
For
example, see figure, in the US United States Department of Veterans Affairs
(VA) the program management life cycle is depicted and describe in the overall
VA IT PROJECT MANAGEMENT FRAMEwork to address the integration of OMB Exhibit
300 project (investment) management activities and the overall project
budgeting process. The VA IT Project Management Framework diagram illustrates
Milestone 4 which occurs following the deployment of a system and the closing
of the project. The project closing phase activities at the VA continues
through system deployment and into system operation for the purpose of
illustrating and describing the system activities the VA considers part of the
project. The figure illustrates the actions and associated artifacts of the VA
IT Project and Program Management process.
International
standards
There
have been several attempts to develop project management standards, such as:
* Capability Maturity Model from the Software
Engineering Institute.
* GAPPS, Global Alliance for Project
Performance Standards – an open source standard describing COMPETENCIES for
project and program managers.
* A Guide to the Project Management Body of
Knowledge from the Project Management Institute (PMI)
* HERMES method, Swiss general project
management method, selected for use in Luxembourg and international
organizations.
* The ISO standards ISO 9000, a family of
standards for quality management systems, and the ISO 10006:2003, for Quality
management systems and guidelines for quality management in projects.
* PRINCE2, PRojects IN Controlled Environments.
* Association for Project Management Body of
Knowledge[33]
* Team Software Process (TSP) from the Software
Engineering Institute.
* Total Cost Management Framework, AACE
International's Methodology for Integrated Portfolio, Program and Project
Management.
* V-Model, an original systems development
method.
* The Logical framework approach, which is
popular in international development organizations.
* IAPPM, The International Association of
Project & Program Management, guide to project auditing and rescuing
troubled projects.
Project
portfolio management
An
increasing number of organizations are using, what is referred to as, project
portfolio management (PPM) as a means of selecting the right projects and then
using project management techniques[34] as the means for delivering the
outcomes in the form of benefits to the performing private or not-for-profit
organization.
