• Cost Reduction is a process, aims at lowering the unit cost of a product manufactured or
service rendered without affecting its quality by using new and improved methods and
techniques. It ascertains substitute ways to reduce the cost of a unit. It ensures savings in per
unit cost and maximisation of profits of the organisation.
• Cost Reduction aims at cutting off the unnecessary expenses which occur during the
production, storing, selling and distribution of the product. To identify cost reduction, the
following are the major elements:
• • Savings in per unit cost.
• • No compromise with the quality of the product.
• • Savings are non-volatile in nature.
2
• Cost Control is a process which focuses on controlling the total cost
through competitive analysis. It is a practice which works to maintain the
actual cost in accordance with the established norms. It ensures that the
cost incurred on an operation should not go beyond the pre-determined
cost.
• Cost Control involves a chain of functions, which starts from preparation
of the budget in relation to the operation, thereafter evaluating the actual
performance, next is to compute the variances between the actual cost &
the budgeted cost and further, to find out the reasons for the same, finally
to implement the necessary actions for correcting discrepancies.
3
• Establishing norms:
The first step in cost control is to set norms or standards
which may serve as yardsticks for measuring performance.
these standards are set on the basis of past performance
adjusted for changes in future and on the basis of studies
conducted.
• Comparison with actual:
The actual cost incurred are compared with established
standard costs to know the level of achievement. The variations
are analysed so as toy arrive at the causes which are
controllable.
• Corrective Action:
Remedial measures are taken to avoid the recurrence of
variation in future and for revision of standards wherever
necessary

Steps in Cost control
Key Differences Between Cost
control and Cost Reduction
5
The activity of maintaining cost as per the established norms is
known as cost control. The activity of decreasing per unit cost by
applying new methods of production in such a way that it does
not affect the quality of the product is known as cost reduction.
Cost Control focuses on decreasing the total cost while cost
reduction focuses on decreasing per unit cost of a product.
Cost Control is temporary in nature. Unlike Cost Reduction which is
permanent.
The process of cost control is completed when the specified target is
achieved. Conversely, the process of cost reduction has no visible
end as it is a continuous process that targets for eliminating
wasteful expenses.
Cost Control does not guarantee quality maintenance, however
100% quality maintenance is assured in case of cost reduction.
Cost Control is a preventive function as it ascertains the cost before
its occurrence. Cost Reduction is a corrective action.
6
• Cost control is the achievement of pre- determined targets of costs.
Cost reduction is the achievement of the real and permanent reduction
in costs.
• Cost control tends to assume a static state of affairs and that standard
once set are not challenged.
Cost reduction assumes the existence of concealed potential saving in
the standards or pre- determined costs set for cost control and that
these standards are always subject to challenge.
• Cost control is concerned with predetermining costs, comparing it with
actual costs, analysing the variances and taking corrective measures.
Cost reduction is not concerned with maintenance of performance
according to predetermined targets. it is rather concerned with finding
out new product design, methods,etc
• Cost control is a part of cost accounting function
Cost reduction may be achieved even when no cost accounting system
is in operation
• Cost control lacks dynamic approach to cost improvement
Cost reduction is more dynamic approach to cost improvement

• ROLE AND IMPORTANCE OF NORMS
• Norms provide safeguards. Although no code can eliminate all
risks, reducing risks to an acceptable level helps.
• Norms have been the primary source for guidance in the
design and construction of building structures for many
decades.
• Norms ensure the economic well being of the community by
reducing potential spread of fire and disease.
• It provides Standards for structure, placement, size, usage,
wall assemblies, fenestration size/locations,
• Norms provide minimum standards for safety, health and
general welfare.
PRINCIPLES FOR DEFINING SPACE NORMS
• BUILDING CODES ARE THE STANDARDS
“CONSERVATION BUILDING CODES” ARE THE KEY
POLICY INSTRUMENT USED BY THE GOVERNMENT TO
LIMIT BUILDING PRESSURE ON ENERGY AND SPACE.
• SPACE NORMS FOCUSES ON LIVING CONDITIONS AND
COMFORT FOR THE OCCUPANTS.
• THESE SERVES AS A MODEL CODE PROVIDING
GUIDELINES FOR REGULATING BUILDING
CONSTRUCTION ACTIVITY.
• THEY EXIHIBIT MINIMUM AND MAXIMUM ROOM SPACE
AND EXITS AND LOCATIONS.
• Standardisation and Simplification
Simplification is a process of product analysis through which
unnecessary varieties and designs are eliminated.Only a
limited number of grades, types and sizes of the product are
retained.
Standardisation is the second step after simplification
towards interchangeable manufacturing. Having selected the
varieties and grades of the products to be retained as much of
its manufacturing details are standardised as possible.
11
• Since manufacturing involves a large number of
decisions from selection of raw material to the
process used for finishing, standardisation of some
of these items reduce unnecessary repetition of
work.
• Use of standard components reduces inventory
costs, ensures interchangeability and makes future
maintenance easier.
• It also reduces component cost since standard
components are manufactures by mass production
methods and are cheaper.
12
• Selection of standard materials ensures physical
performance and guarantees failure-free
operation. Use of standard methods of production
enables comparisons to be made of the standard
and actual manufacturing time
• The purpose of standardisation is, therefore, on
one hand, efficiency and economy in the use of
human effort and on the other economy of
material varieties and stock quantities and
therefore reduction in cost and increase in
turnover.

  • 2. • Cost Reduction is a process, aims at lowering the unit cost of a product manufactured or service rendered without affecting its quality by using new and improved methods and techniques. It ascertains substitute ways to reduce the cost of a unit. It ensures savings in per unit cost and maximisation of profits of the organisation. • Cost Reduction aims at cutting off the unnecessary expenses which occur during the production, storing, selling and distribution of the product. To identify cost reduction, the following are the major elements: • • Savings in per unit cost. • • No compromise with the quality of the product. • • Savings are non-volatile in nature. 2
  • 3. • Cost Control is a process which focuses on controlling the total cost through competitive analysis. It is a practice which works to maintain the actual cost in accordance with the established norms. It ensures that the cost incurred on an operation should not go beyond the pre-determined cost. • Cost Control involves a chain of functions, which starts from preparation of the budget in relation to the operation, thereafter evaluating the actual performance, next is to compute the variances between the actual cost & the budgeted cost and further, to find out the reasons for the same, finally to implement the necessary actions for correcting discrepancies. 3
  • 4. • Establishing norms: The first step in cost control is to set norms or standards which may serve as yardsticks for measuring performance. these standards are set on the basis of past performance adjusted for changes in future and on the basis of studies conducted. • Comparison with actual: The actual cost incurred are compared with established standard costs to know the level of achievement. The variations are analysed so as toy arrive at the causes which are controllable. • Corrective Action: Remedial measures are taken to avoid the recurrence of variation in future and for revision of standards wherever necessary 4 Steps in Cost control
  • 5. Key Differences Between Cost control and Cost Reduction 5
  • 6. The activity of maintaining cost as per the established norms is known as cost control. The activity of decreasing per unit cost by applying new methods of production in such a way that it does not affect the quality of the product is known as cost reduction. Cost Control focuses on decreasing the total cost while cost reduction focuses on decreasing per unit cost of a product. Cost Control is temporary in nature. Unlike Cost Reduction which is permanent. The process of cost control is completed when the specified target is achieved. Conversely, the process of cost reduction has no visible end as it is a continuous process that targets for eliminating wasteful expenses. Cost Control does not guarantee quality maintenance, however 100% quality maintenance is assured in case of cost reduction. Cost Control is a preventive function as it ascertains the cost before its occurrence. Cost Reduction is a corrective action. 6
  • 7. • Cost control is the achievement of pre- determined targets of costs. Cost reduction is the achievement of the real and permanent reduction in costs. • Cost control tends to assume a static state of affairs and that standard once set are not challenged. Cost reduction assumes the existence of concealed potential saving in the standards or pre- determined costs set for cost control and that these standards are always subject to challenge. • Cost control is concerned with predetermining costs, comparing it with actual costs, analysing the variances and taking corrective measures. Cost reduction is not concerned with maintenance of performance according to predetermined targets. it is rather concerned with finding out new product design, methods,etc • Cost control is a part of cost accounting function Cost reduction may be achieved even when no cost accounting system is in operation • Cost control lacks dynamic approach to cost improvement Cost reduction is more dynamic approach to cost improvement 7
  • 8. BASIS OF COMPARISON Meaning COST CONTROL A technique used for maintaining the costs as per the set standards is known as Cost Control COST REDUCTION A technique used to economise the unit cost without lowering the quality of the product is known as Cost Reduction Savings in Total Cost Cost Per Unit Retention of Quality Not Guaranteed Guaranteed Nature Temporary Permanent Emphasis on Past and Present Cost Present and Future Cost Ends when The pre-determined target is achieved No end Type of Function Preventive Corrective Comparison Chart 8
  • 9. • ROLE AND IMPORTANCE OF NORMS • Norms provide safeguards. Although no code can eliminate all risks, reducing risks to an acceptable level helps. • Norms have been the primary source for guidance in the design and construction of building structures for many decades. • Norms ensure the economic well being of the community by reducing potential spread of fire and disease. • It provides Standards for structure, placement, size, usage, wall assemblies, fenestration size/locations, • Norms provide minimum standards for safety, health and general welfare.
  • 10. PRINCIPLES FOR DEFINING SPACE NORMS • BUILDING CODES ARE THE STANDARDS “CONSERVATION BUILDING CODES” ARE THE KEY POLICY INSTRUMENT USED BY THE GOVERNMENT TO LIMIT BUILDING PRESSURE ON ENERGY AND SPACE. • SPACE NORMS FOCUSES ON LIVING CONDITIONS AND COMFORT FOR THE OCCUPANTS. • THESE SERVES AS A MODEL CODE PROVIDING GUIDELINES FOR REGULATING BUILDING CONSTRUCTION ACTIVITY. • THEY EXIHIBIT MINIMUM AND MAXIMUM ROOM SPACE AND EXITS AND LOCATIONS.
  • 11. • Standardisation and Simplification Simplification is a process of product analysis through which unnecessary varieties and designs are eliminated.Only a limited number of grades, types and sizes of the product are retained. Standardisation is the second step after simplification towards interchangeable manufacturing. Having selected the varieties and grades of the products to be retained as much of its manufacturing details are standardised as possible. 11
  • 12. • Since manufacturing involves a large number of decisions from selection of raw material to the process used for finishing, standardisation of some of these items reduce unnecessary repetition of work. • Use of standard components reduces inventory costs, ensures interchangeability and makes future maintenance easier. • It also reduces component cost since standard components are manufactures by mass production methods and are cheaper. 12
  • 13. • Selection of standard materials ensures physical performance and guarantees failure-free operation. Use of standard methods of production enables comparisons to be made of the standard and actual manufacturing time • The purpose of standardisation is, therefore, on one hand, efficiency and economy in the use of human effort and on the other economy of material varieties and stock quantities and therefore reduction in cost and increase in turnover. 13
