6.01 PROJECT CONTROL
Project Control is a process for controlling the investment of resources in an asset. In TCM,
project control is the recursive process cycle that is nested within the "do" step of the strategic
asset management process cycle. A project is a temporary endeavor an enterprise undertakes to
create, modify, maintain, or retire a unique asset. Being a temporary and therefore unique
endeavor, projects are by nature uncertain and that element of risk puts a premium on control and
discipline.
Project Controls can be defined as - Management action, either preplanned to achieve the desired
result or taken as a corrective measure prompted by the monitoring process.
The project control team analyzes, measures, evaluates and controls project's revenue and cost.
Fundamental to our business efficiency, they monitor progress against schedule, cost, details of
contract and clients expectations. The team implement corrective measures when necessary and
manage of all types of risk.
6.02 FUNDAMENTAL OBJECTIVES OF CONTROL
The fundamental purposes / objectives of control is,
 to maximize the use of scarce resources
 to achieve purposeful behaviour of organization members.
 to visualize whether resources are utilized
 to find out deviations between planned performance and actual performance
 to suggest corrective actions where necessary and finally.
 to complete the whole sequence of management process.

 to regulate of results through the attention of activities.
 to steward of organization assets.
6.03 TYPES OF CONTROL SYSTEM
Project control is not simply waiting for things to go wrong and then fixing it. It is chiefly to have
systems to identify problems before they manifest themselves. There are three basic types of
control mechanisms- cybernetic, go/no-go, and post-performance.
1. Cybernetic Control: This is the most common kind of control mechanism. A project has
inputs and outputs. The outputs can be in the form of milestones that have to be met. Cybernetic
controls focus on the outputs. If these milestones or outputs do not measure up to the set
standards, then the situation is investigated to see if there is a sufficient cause to change patterns
of activity.
2. Go/No-go Control: Go/no-go control takes the form of testing to make sure that certain
preconditions are met before a task is undertaken. This type of control can be used for a specific
part of the project too. Go/no-go controls are linked to the actual plans and are not independently
set on a calendar.
3. Post-performance Control: Post-performance controls are applied after the completion of the
project or the task, The focus here is not on altering what has already happened but in making
sure that good and bad practices are recorded for being of help in future projects. The post-
performance controls include a set of recommendations on how to improve future projects.
Explain in brief, the three main types of control system.

6.04 VARIANCE ANALYSIS APPROACH
In project management, variance analysis helps maintain control over a project's expenses by
monitoring planned versus actual costs. Effective variance analysis can help a company spot
trends, issues, opportunities and threats to short-term or long-term success.
1. Budget vs. Actual Costs: Variance analysis is important to assist with managing budgets by
controlling budgeted versus actual costs. In program and project management, for example,
financial data are generally assessed at key intervals or milestones. For instance, a monthly
closing report might provide quantitative data about expenses, revenue and remaining
inventory levels. Variances between planned and actual costs might lead to adjusting business
goals, objectives or strategies.
2. Materiality: A materiality threshold is the level of statistical variance deemed meaningful, or
worth noting. This will vary from company to company. For example, a sales target variance
of Tk.100,000 will be more material to a small business retailer than to a national retailer

accustomed to generating billions in annual revenues. Conversely, a 2 percent cost overrun
might be immaterial for a small business but translate into millions of dollars for a large
company.
3. Relationships: Relationships between pairs of variables might also be identified when
performing variance analysis. Positive and negative correlations are important in business
planning. As an example, variance analysis might reveal that when sales for widget A rise
there is a correlated rise in the sales for widget B. Improved safety features for one product
might result in sales increases. This information might be used to transfer this success to
other similar products.
4. Forecasting: An important type of prediction is business forecasting. It uses patterns of past
business data to construct a theory about future performance. Variance data are placed into
context that allows an analyst to identify factors such as holidays or seasonal changes as the
root cause of positive or negative variances. For example, the monthly pattern of sales of
television sets over five years might identify a positive sales trend leading up to the beginning
of the school year. As a result, forecasts for television sales over the next 12 months might
include increasing inventory by a certain percentage — based on historical sales patterns —
in the weeks before the start of local universities' fall term.
In conclusion we can say that variance analysis is the comparison of planned results and actual
results. The planned results may be found in the Project Management Plan and compared to work
performance information. The project manager should be certain that the data itself is
trustworthy, and then examine how much variance exists between planned and actual results.
Then, the potential impact and causes of any variance should be analyzed, along with determining
what action may be needed.
6.05 TOOLS USED BY PROJECT MANAGERS
A project manager cannot execute his/her job without a proper set of tools. These tools do not
have to be renowned software or something, but it can pretty well be simple and proven
techniques to manage project work. Having a solid set of project management tools always makes
project managers' work pleasurable and productive. Following are some of those tools used by
project managers in all domains:
1. Project Plan: All the projects that should be managed by a project manager should have a
project plan. The project plan details many aspects of the project to be executed.
2. Milestone Checklist: This is one of the best tools the project manager can use to determine
whether he or she is on track in terms of the project progress.
3. Gantt Chart: Gantt chart illustrates the project schedule and shows the project manager the
interdependencies of each activity. Gantt charts are universally used for any type of project
from construction to software development.
4. Project Management Softwares: With the introduction of computer technology, there have
been a number of software tools specifically developed for project management purpose. MS
Project is one such tool that has won the hearts of project managers all over the world.

5. Project Reviews: A comprehensive project review mechanism is a great tool for project
management. More mature companies tend to have more strict and comprehensive project
reviews as opposed to basic ones done by smaller organizations.
6. Delivery Reviews: Delivery reviews make sure that the deliveries made by the project team
meet the customer requirements and adhere to the general guidelines of quality.
7. Score Cards: When it comes to performance of the project team, a scorecard is the way of
tracking it. Every project manager is responsible of accessing the performance of the team
members and reporting it to the upper management and HR.
6.06 CHARACTERISTICS OF A GOOD CONTROL SYSTEM
Effective control systems have certain characteristics. For a control system to be effective, it must
be:
1. Accurate: Information on performance must be accurate. Evaluating the accuracy of the
information they receive is one of the most important control tasks that managers face.
2. Timely: Information must be collected, routed, and evaluated quickly if action is to be taken
in time to produce improvements.
3. Objective and Comprehensible: The information in a control system should be
understandable and be seen as objective by the individuals who use it. A difficult-to
understand control system will cause unnecessary mistakes and confusion or frustration
among employees.
4. Focused on Strategic Control Points: The control system should be focused on those areas
where deviations from the standards are most likely to take place or where deviations would
lead to the greatest harm.
5. Economically Realistic: The cost of implementing a control system should be less than, or at
most equal to, the benefits derived from the control system.
6. Organizational Realistic: The control system has to be compatible with organizational
realities and all standards for performance must be realistic.
7. Coordinated with the Organization's Work Flow: Control information needs to be
coordinated with the flow of work through the organization for two reasons: (1) each step in
the work process may affect the success or failure of the entire operation, (2) the control
information must get to all the people who need to receive it.
8. Flexible: Controls must have flexibility built into them so that the organizations can react
quickly to overcome adverse changes or to take advantage of new opportunities.
9. Prescriptive and Operational: Control systems ought to indicate, upon the detection of the
deviation from standards, what corrective action should be taken.
10. Accepted by Organization Members: For a control system to be accepted by organization
members, the controls must be related to meaningful and accepted goals.
These characteristics can be applied to controls at all levels of the organization.
6.07 CYBERNETIC CONTROL SYSTEM
What tools are available to the project manager to use in controlling a project?
BBA (Professional) 2014
Identify some characteristics of a good control system. BBA (Professional) 2014

The term cybernetics comes from the ancient Greek word kybernetikos (“good at
steering”), referring to the art of the helmsman. Cybernetics, control theory as it is
applied to complex systems. Cybernetics is associated with models in which a monitor
compares what is happening to a system at various sampling times with some standard of
what should be happening, and a controller adjusts the system’s behaviour accordingly.
