40.1 Cost
Management:
It is widely used in business today and is the process whereby
companies use cost accounting to
report or control various costs of doing business. Cost
Management generally describes
approach and activities of managers in short range and long
range planning and cost decisions
that incorporate value for customer and lower costs of product
and services.
Manager make decisions on amount and kind of material used,
changes of plant processes,
changes in product designs and information from accounting
system helps managers make such
decisions, but information and accounting system not “cost
management” project cost
management broad focus includes continuous control of costs.
Planning and cost is usually
linked with revenue and profit planning.
In the context of project:
Cost management involves overall planning, co-ordination, and
control and reporting of all
cost-related aspects from “project initiation” to “operation and
maintenance”.
Process of identifying all costs associated with investment,
making informed choices about
options that will deliver best “value for money” and managing
those costs throughout life of
project. Techniques (value management) help to improve value and
reduce costs.
40.2 Cost Control:
Cost control is equally important to all companies, regardless
of size. Small companies
generally have tighter monetary controls, mainly because of the
risk with the failure of as little
as one project, but with less sophisticated control techniques.
Large companies may have the
luxury to spread project losses over several projects, whereas
the small company may have few
projects.
Cost control is not only "monitoring" of costs and recording
perhaps massive quantities of data,
but also analyzing of the data in order to take corrective
action before it is too late. Cost control
should be performed by all personnel who incur costs, not merely
the project office. Cost
control implies good cost management, which must include:
- Cost estimating
- Cost accounting
- Project cash
flow
- Company cash
flow
- Direct labor
costing
- Overhead rate
costing
- Others, such as
incentives, penalties, and profit-sharing
40.3 Management Cost and Control System (MCCS):
Cost control is actually a subsystem of the
Management Cost and Control System
(MCCS)
rather than a complete system per se. This is shown in Figure
40.1,
where the Management Cost
and Control System (MCCS) is represented as a two cycle process:
a planning cycle and an
operating cycle. The operating cycle is what is commonly
referred to as the cost control system.
Failure of a cost control system to accurately describe the true
status of a project does not
necessarily imply that the cost control system is at fault. Any
cost control system is only as
good as the original plan against which performance will be
measured. It is more common for
the plan to be at fault than the control system.
Figure 40.1:
Phases of a Management Cost and Control System
Therefore, the designing of a company's planning system must
take into account the cost control
system as well.
For this reason, it is common for the planning cycle to be referred to as
planning and control, whereas the operating cycle is referred to
as cost and control.
Note that the planning and control system selected must be able
to satisfy management's needs
and requirements in order that they can accurately project the
status toward objective
completion. The purpose of any management cost and control
system is to establish policies,
procedures, and techniques that can be used in the day-to-day
management and control of
projects and programs. The planning and control system must,
therefore, provide information
that:
Gives a picture
of true work progress
Will relate
cost and schedule performance
Identifies
potential problems with respect to their sources.
Provides
information to project managers with a practical level of summarization
Demonstrates
that the milestones are valid, timely, and auditable
The planning and control system, in addition to being a tool by
which objectives can be defined
that is
hierarchy of objectives and
organization accountability,
exists as a tool to develop
planning, measure progress, and control change. As a tool for
planning, the system must be able
to:
Plan and
schedule work
Identify those
indicators that will be used for measurement
Establish
direct labor budgets
Establish
overhead budgets
Identify
management reserve
The project budget that is the final result of the planning
cycle of the MCCS must be
reasonable, attainable, and based on contractually negotiated
costs and the statement of work.
The basis for the budget is historical cost, best estimates, or
industrial engineering standards.
310
The budget must identify planned manpower requirements,
contract-allocated funds, and
management reserve. Establishing budgets requires that the
planner fully understand the
meaning of standards.
We should know that there are two categories of standards.
Performance results standards are
quantitative measurements and include such items as quality of
work, quantity of work, cost of
work, and time-to-complete. Process standards are qualitative,
including personnel, functional,
and physical factors relationships.
Standards are advantageous in that they provide a means for
unity, a basis for effective control,
and an incentive for others. The disadvantage of standards is
that performance is often frozen,
and employees are quite often unable to adjust to the
differences. As a tool for measuring
progress and controlling change, the systems must be able to:
- Measure
resources consumed
- Measure status
and accomplishments
- Compare
measurements to projections and standards
- Provide the
basis for diagnosis and re-planning
In using the Management Cost and Control System (MCCS), the
following guidelines
usually apply:
• The level of
detail is specified by the project manager with approval by top management.
• Centralized
authority and control over each project are the responsibility of the project
management division.
• For large
projects, the project manager may be supported by a project team for utilization
of
the Management Cost and Control System (MCCS).
Almost all project planning and control systems have
identifiable design requirements.
These include:
- A common
framework from which to integrate time, cost, and technical performance
- Ability to
track progress of significant parameters
- Quick response
- Capability for
end-value prediction
- Accurate and
appropriate data for decision making by each level of management
- Full exception
reporting with problem analysis capability
- Immediate
quantitative evaluation of alternative solutions
Management Cost and Control System (MCCS) planning activities
include:
Contract
receipt (if applicable)
Work
authorization for project planning
Work breakdown
structure (WBS)
Subdivided work
description
Schedules
Planning charts
Budgets
Management Cost and Control System (MCCS) planning charts are
worksheets used to create
the budget. These charts include planned labor in hours and
material dollars. Management Cost
and Control System (MCCS) planning is accomplished in one of
these ways:
One level below
the lowest level of the Work Breakdown Structure (WBS)
At the lowest
management level
By cost element
or cost account
311
Even with a fully developed planning and control system, there
are numerous benefits and costs.
The appropriate system must consider a cost-benefit analysis,
and include such items as:
• Project
benefits:
o Planning and
control techniques facilitate:
— Derivation of output specifications (project objectives)
— Delineation of required activities (work)
— Coordination and communication between organizational units
— Determination of type, amount, and timing of necessary
resources
— Recognition of high-risk elements and assessment of
uncertainties
— Suggestions of alternative courses of action
— Realization of effect of resource level changes on schedule
and output
performance
— Measurement and reporting of genuine progress
— Identification of potential problems
— Basis for problem solving, decision making, and corrective
action
— Assurance of coupling between planning and control
• Project cost:
o Planning and
control techniques require:
— New forms (new systems) of information from additional sources
and
incremental processing (managerial time, computer expense, etc.)
— Additional personnel or smaller span of control to free
managerial time for
planning and control tasks (increased overhead)
— Training in use of techniques (time and materials)
A well-disciplined Management Cost and Control System (MCCS)
will produce the
- following results:
- Policies and
procedures that will minimize the ability to distort reporting
- Strong
management emphasis on meeting commitments
- Weekly team
meetings with a formalized agenda, action items, and minutes.
- Top-management
periodic review of the technical and financial status
- Simplified
internal audit for checking compliance with procedures
Furthermore, for Management Cost and Control System (MCCS) to be
effective, both the
scheduling and budgeting systems must be disciplines and formal
in order to prevent
inadvertent or arbitrary budget or schedule changes. This does
not
mean that the baseline budget
and schedule, once established, is static or inflexible. Rather,
it means that changes must be
controlled and result only from deliberate management actions.
Disciplined use of Management Cost and Control System (MCCS) is
designed to put pressure
on the project manager to perform exceptionally good project
planning so that changes will be
minimized. As an example, government subcontractors may not:
- Make
retroactive changes to budgets or costs for work that has been completed.
- Re-budget
work-in-progress activities
- Transfer work
or budget independently of each other
- Reopen closed
work packages
In some industries, the Management Cost and Control System
(MCCS) must be used on all
contracts of $2 million or more, including firm fixed-price
efforts. The fundamental test of
whether to use the MCCS is to determine whether the contracts
have established end-item
deliverables, either hardware or computer software, that must be
accomplished through
measurable efforts.
312
Currently, two new programs are being used by the government and
industry in conjunction
with the Management Cost and Control System (MCCS) as an attempt
to improve effectiveness
in cost control. The zero-base budgeting program was established
to provide better estimating
techniques for the verification portion of control. The
design-to-cost program assists the
decision-making part of the control process by identifying a
decision-making framework from
which re-planning can take place.
40.4 Understanding Control:
Effective management of a program during the operating cycle
requires that a well-organized
cost and control system be designed, developed, and implemented
so that immediate feedback
can be obtained, whereby the up-to-date usage or resources can
be compared to target objectives
established during the planning cycle. The requirements for an
effective control system (for
- both cost and schedule/performance) should include:
- Thorough
planning of the work to be performed to complete the project
- Good estimating
of time, labor, and costs
- Clear
communication of the scope of required tasks
- A disciplined
budget and authorization of expenditures
- Timely
accounting of physical progress and cost expenditures
- Periodic
re-estimation of time and cost to complete remaining work
- Frequent,
periodic comparison of actual progress and expenditures to schedules and
budgets, both at the time of comparison and at project
completion
It is essential that the management must compare the time, cost,
and performance of the
program to the budgeted time, cost, and performance, not
independently but in an integrated
manner. Being within one's budget at the proper time serves no
useful purpose if performance is
only 75 percent. Likewise, having a production line turn out
exactly 200 items, when planned,
loses its significance if a 50 percent cost overrun is incurred.
All three resource parameters (time, cost, and performance) must
be analyzed as a group, or else
we might ''win the battle but lose the war." The use of the
expression "management cost and
control system" is vague in that the implication is made that
only costs are controlled. This is
not true— an effective control system monitors schedule and
performance as well as costs by
setting budgets, measuring expenditures against budgets and
identifying variances, assuring that
the expenditures are proper, and taking corrective action when
required.
Previously, we defined the Work Breakdown Structure (WBS) as the
element that acts as the
source from which all costs and controls must emanate. The Work
Breakdown Structure (WBS)
is the total project broken down into successively lower levels
until the desired control levels
are established. The Work Breakdown Structure (WBS) therefore
serves as the tool from which
performance can be subdivided into objectives and
sub-objectives. As work progresses, the
WBS provides the framework on which costs, time, and
schedule/performance can be compared
against the budget for each level of the WBS.
The first purpose of control therefore becomes a verification
process accomplished by the
comparison of actual performance to date with the predetermined
plans and standards set forth
in the planning phase. The comparison serves to verify that:
• The objectives
have been successfully translated into performance standards.
• The performance
standards are, in fact, a reliable representation of program activities and
events.
• Meaningful
budgets have been established such that actual versus planned comparisons can
be made.
313
In other words, the comparison verifies that the correct
standards were selected, and that they
are properly used. The second purpose of control is that of
decision making. Three useful
reports are required by management in order to make effective
and timely decisions:
• The project
plan, schedule, and budget prepared during the planning phase.
• A detailed
comparison between resources expended to data and those predetermined. This
includes an estimate of the work remaining and the impact on
activity completion.
• A projection of
resources to be expended through program completion.
Afterwards, these reports are then supplied to both the managers
and the doers. Three useful
results arise through the use of these three reports, generated
during a thorough decision-making
stage of control:
• Feedback to
management, the planners, and the doers.
• Identification
of any major deviations from the current program plan, schedule, or budget.
• The opportunity
to initiate contingency planning early enough that cost, performance, and
time requirements can undergo corrected action without loss of
resources.
• These reports,
if properly prepared, provide management with the opportunity to minimize
downstream changes by making proper corrections here and now. As
shown in Figures 40.2
and 40.3, possible cost reductions are usually available more
readily in the early project
phases, but are reduced as we go further into the project
life-cycle phases. Downstream the
cost for changes could easily exceed the original cost of the
project. This is an example of
the "iceberg" syndrome, where problems become evident too late
in the project to be solved
easily, resulting in a very high cost to correct them.

40.5 Operating Cycle:
The Management Cost and Control System (MCCS) takes on paramount
importance during the
operating cycle of the project. The operating cycle is composed
of four phases:
- Work
authorization and release (phase II)
- Cost data
collection and reporting (phase III)
- Cost analysis
(phase IV)
- Reporting:
customer and management (phase V)
These four phases, when combined with the planning cycle
(phase I),
constitute a closed system
network that forms the basis for the management cost and control
system.
Phase II is
considered as work release. After planning is completed and a contract is
received,
work is authorized via a work description document. The work
description, or project work
authorization form, is a contract that contains the narrative
description, organization, and time
frame for each
Work Breakdown Structure
(WBS) level. This multipurpose form is used to
release the contract, authorize planning, record detail
description of the work outlined in the
Work Breakdown Structure (WBS), and release work to the
functional departments.
Note that the contract services may require a work description
form to release the contract. The
contractual work description form sets forth general contractual
requirements and authorizes
program management to proceed.
Program management may then issue a subdivided work description
form to the functional units
so that work can begin. The subdivided work description may also
be issued through the
combined efforts of the project team, and may be revised or
amended when either the scope of
time frame changes. The subdivided work description generally is
not used for efforts longer
than ninety days and must be "tracked" as if a project in
itself. This subdivided work description
form sets forth contractual requirements and planning guidelines
for the applicable performing
organizations.
Also, the subdivided work description package established during
the proposal and updated
after negotiations by the program team is incrementally released
by program management to the
work control centers in manufacturing engineering, publications,
and program management as
the authority for release of work orders to the performing
organizations. The subdivided work
description specifies how contractual requirements are to be
accomplished, the functional
organizations involved, and their specific responsibilities, and
authorizes the expenditure of
resources within a particular time frame.
The work control center assigns a work order number to the
subdivided work description form,
if no additional instructions are required, and releases the
document to the performing
organizations. If additional instructions are required, the work
control center can prepare a more
detailed work release document (shop traveler, tool order, work
order release), assign the
applicable work order number, and release it to the performing
organization.
In addition to this, a work order number is required for all
in-house direct and indirect charging.
The work order number also serves as a cross-reference number
for automatic assignment of the
indentured work breakdown structure number to labor and material
data records in the
computer.
In case of small companies, they can avoid this additional
paperwork cost by going
directly from an awarded contract to a single work order, which
may be the only work
order needed for the entire contract.
40.6 Cost Account Codes:
It must be noted that since project managers control resources
through the line managers rather
than directly, project managers end up controlling direct labor
costs by opening and closing
work orders. Work orders define the charge numbers for each cost
account. By definition, a cost
account is an identified level at a natural intersection point
of the work breakdown structure and
the
Organizational Breakdown Structure (OBS)
at which functional responsibility for
the work
is assigned, and actual direct labor, material, and other direct
costs are compared with actual
work performed for management control purposes.
Cost accounts are the focal point of the Management Cost and
Control System (MCCS) and
may comprise several work packages, as shown in Figure 40.4.
Work packages are detailed
short –span job or material items identified for the
accomplishment of required work. To
illustrate this, consider the cost account code breakdown shown
in Figure 40.5 and the work
authorization form shown in Figure 40.6. The work authorization
form specifically identifies the
cost centers that are "open" for this charge number, the
man-hours available for each cost
center, and the operational time period for the charge number.
Because the exact dates of
operation are completely defined, the charge number can be
assigned perhaps as much as a year
in advance of the work-begin date. This can be shown
pictorially, as in Figure 40.7.
Figure 40.4:
Cost Account Intersection
If the man-hours are assigned to cost center 2400, then any 24xx
cost center can use this charge
number. If the work authorization form specifies cost center
2610, then any 261x cost center
can use the charge number.
However, if cost center 2623 is specified, then no lower cost
accounts exist, and this is the only
cost center that can use this work order charge number. In other
words, if a charge number is
opened up at the department level, then the department manager
has the right to subdivide the
assigned man-hours among the various sections and subsections.
Company policy usually identifies the permissible cost center
levels that can be assigned in the
work authorization form. These permissible levels are related to
the work breakdown structure
level. For example, cost center 5000 (i.e., divisional) can be
assigned at the project level of the
work breakdown structure, but only department, sectional, or
sub-sectional cost accounts can be
assigned at the task level of the work breakdown structure.
316
If a cost center needs additional time or additional man-hours,
then a cost account change notice
form must be initiated, usually by the requesting cost center,
and approved by the project office.
The following Figure 40.8 shows a typical cost account change
notice form.
317
Cost Account Change Notice (CACN)
Almost all large companies have computerized cost control and
reporting systems. Small
companies have manual or partially computerized systems. The
major difficulty in using the
cost account code breakdown and the work authorization form
(shown in Figures 40.5 and 40.6)
is related to whether the employees fill out time cards, and
frequency with which the time cards
are filled out.
Project-driven organizations fill out time cards at least once a
week, and the cards are inputted
to a computerized system. Non–project-driven organizations fill
out time cards on a monthly
basis, with computerization depending on the size of the
company.
Cost data collection and reporting constitute the second phase
of the operating cycle of the
Management Cost and Control System (MCCS).
Actual cost for work performed (ACWP)and
the budgeted
cost for work performed (BCWP)
for each contract or in-house project
are
accumulated in detailed cost accounts by cost center and cost
element, and reported in
accordance with the flow charts shown in Figure 40.9. These
detailed elements, for both actual
costs incurred and the budgeted cost for work performed, are
usually printed out monthly for all
levels of the work breakdown structure. In addition, weekly
supplemental direct labor reports
can be printed showing the actual labor charge incurred, and can
be compared to the predicted
efforts.
Figure 40.9:
Cost Data Collection and Reporting Flow Chart
The following Table 40.1 shows a typical weekly labor report.
The first column identifies the
Work Breakdown Structure (WBS) number. If more than one work
order were assigned to this
Work Breakdown Structure (WBS) element, then the work order
number would appear under
the WBS number. This procedure would be repeated for all work
orders under the same WBS
number. The second column contains the cost centers charging to
this WBS element (and
possibly work order numbers). Cost Center 41xx represents
department 41 and is a rollup of
Cost Centers 4110, 4115, and 4118. Cost Center 4xxx represents
the entire division and is a
318
rollup of all 4000-level departments. Cost Center xxxx
represents the total for all divisions
charging to this Work Breakdown Structure (WBS) element. The
weekly labor reports must list
all cost centers authorized to charge to this WBS element,
whether or not they have incurred
any costs over the last reporting period.
Weekly Labor Report
Note that most weekly labor reports provide current month
subtotals and previous month totals.
Although these also appear on the detailed monthly report, they
are included in the weekly
report for a quick and dirty comparison. Year-to-date totals are
usually not on the weekly report
unless the users request them for an immediate comparison to the
estimate at completion (EAC)
and the work order release.
Weekly labor output is a vital tool for members of the program
office in that these reports can
indicate trends in cost and performance in sufficient time for
contingency plans to be
established and implemented. If these reports are not available,
then cost and labor overruns
would not be apparent until the following month when the
detailed monthly labor, cost, and
materials output was obtained. In Table 40.1, Cost Center 4110
has spent its entire budget. The
work appears to be completed on schedule. The responsible
program office team may wish to
eliminate this cost center's authority to continue charging to
this Work Breakdown Structure
(WBS) element by issuing a new SWD or work order canceling this
department's efforts. Cost
Center 4115 appears to be only halfway through.
If time is becoming short, then Cost Center 4115 must add
resources in order to meet
requirements. Cost Center 4443 appears to be heading for an
overrun. This could also indicate a
management reserve. In this case the responsible program team
member feels that the work can
be accomplished in fewer hours.
Work order releases are used to authorize certain cost centers
to begin charging their time to a
specific cost reporting element. Work orders specify hours, not
dollars. The hours indicate the
''targets" that the program office would like to have the
department shoot for. If the program
office wished to be more specific and "compel" the departments
to live within these hours, then
the budgeted
cost for work scheduled (BCWS)
should be changed to reflect the reduced
hours.
Four categories of cost data are normally accumulated:
Labor
Material
Other direct
charges
Overhead
319
We know that the project managers can maintain reasonable
control over labor, material, and
other direct charges.
On the other hand, overhead costs are calculated yearly or
monthly and applied retroactively to
all applicable programs. Management reserves are often used to
counterbalance the effects of
adverse changes in overhead rates.
40.7 Budgets:
The project budget, which is the final result of the planning
cycle of the Management Cost and
Control System (MCCS), must be
reasonable, attainable,
and based on:
• Contractually
negotiated costs, and
• The statement
of work
The basis for the budget is:
• Historical
cost,
• Best estimates,
or
• Industrial
engineering standards
The budget must identify:
• Planned
manpower requirements,
• Contract
allocated funds, and
• Management
reserve.
All budgets must be traceable through the budget "log," which
includes:
• Distributed
budget
• Management
reserve
• Undistributed
budget
• Contract
changes
It is important to note that the management reserve is the
dollar amount established by the
project office to budget for all categories of unforeseen
problems and contingencies resulting in
out-of-scope work to the performers. Management reserve should
be used for tasks or dollars,
such as rate changes, and not to cover up bad planning estimates
or budget overruns. When a
significant change occurs in the rate structure, the total
performance budget should be adjusted.
In addition to the "normal" performance budget and the
management reserve budget, there also
exists the following:
• Undistributed
budget, which is that budget
associated with contract changes where time
constraints prevent the necessary planning to incorporate the
change into the performance
budget. (This effort may be time-constrained.)
• Unallocated budget,
which represents a logical grouping of contract tasks that have
not yet been identified and/or authorized.
Variance:
A variance is defined as any schedule, technical performance, or
cost deviation from a specific
plan. Variances are used by all levels of management to verify
the budgeting system and the
scheduling system. The budgeting and scheduling system variance
must be compared together
because:
• The cost
variance compares deviations only from the budget and does not provide a
measure of comparison between work scheduled and work
accomplished.
320
• The scheduling
variance provides a comparison between planned and actual performance
but does not include costs.
There are two primary methods of measurement:
• Measurable
efforts: Discrete
increments of work with a definable schedule for
accomplishment, whose completion produces tangible results.
• Level of
effort: Work that does
not lend itself to subdivision into discrete scheduled
increments of work, such as project support and project control.
Variances are used on both types of measurement:
In order to calculate variances we must define the three basic
variances for budgeting and actual
costs for work scheduled and performed. Archibald defines these
variables:
• Budgeted cost
for work scheduled (BCWS) is the budgeted amount of cost for work
scheduled to be accomplished plus the amount or level of effort
or apportioned effort
scheduled to be accomplished in a given time period.
• Budget cost for
work performed (BCWP) is the budgeted amount of cost for completed
work, plus budgeted for level of effort or apportioned effort
activity completed within a
given time period. This is sometimes referred to as "earned
value."
• Actual cost for
work performed (ACWP) is the amount reported as actually expended in
completing the work accomplished within a given time period. |
