Business scenario post GATT ....

• Introduction of GATT ( General Agreement on Tariffs and trade ) under the WTO in the yr 1995

• reduced trade barriers amongst global players thru’

o Export subsidies ,

o lifting of quantitative restrictions and

o reduction in tariff rates (from 20% -1950 to 3.6% -2010)

o s How it affected the businesses ! …………

Page 6: Procurement : Resisting price increase

The survival mantra has become

• “Survival of the fittest”

Survival of the best

Cost ,

quality and

the fastest

Page 7: Procurement : Resisting price increase

Inflation and how to beat it

Inflation is a sustained increase in the general price

level of goods and services over a period of time

Inflation occurs due to an imbalance between demand

and supply of money, changes in production and

distribution cost or increase in taxes on products

It could be :

• Negative , or

• Positive

Let us understand thru major cost elements of a

Product !

Page 10: Procurement : Resisting price increase

• Supply-chain executives have significant role in the operating expenses cost of goods sold and

• hence have a major role in margin management

Page 11: Procurement : Resisting price increase

Performance Measures qualitative vs quantitative

• When analyzing SC performance, qualitative evaluations such as

– Good

– Fair

– Adequate and

– Poor

• As a result, quantitative performance measures are often preferred to such qualitative evaluations.

are vague and difficult to arrive at any meaningful conclusion.

Page 12: Procurement : Resisting price increase

Performance monitoring of SC partners

Should include :

• Quality

• OTD

• Cost

• Service

Once the performance of the SC operations has been measured and

performance gaps identified, it becomes important to identify what activities should be performed to close those gaps

Page 13: Procurement : Resisting price increase

• A team from Focal Organization visits the Vendor and

allocates points against a number of queries in a

questionnaire.

• Actual working of the quality department is audited by

examining records, analysis of the system and talking to

people on the spot.

• Rating should be numeric ... , ... , ... , ....scale

• After determining which factors are critical, a method is

devised that allows the vendor to be judged or rated on

each individual factor.

A good supplier helps our organization to be more efficient,

produce higher quality products or services, reduce

costs, and increase profits.

A poor performer can disrupt our operations, make our

organization fail in the eyes of our customers, increase

our costs, and threaten our profits

hence need for Vendor development .........

Value Engineering (value analysis)

• VE is a systematic and organized approach to provide the necessary functions of a product / service / process at the lowest cost.

• Value engineering promotes the substitution of materials and methods with less expensive alternatives, without sacrificing functionality.

• These substitutes were often found to reduce costs and provided equal or better performance.

• Value, as defined, is the ratio of function to cost , V = F

C

• Alternately : Value = (Performance + Capability)/Cost = Function/Cost

• Value can therefore be increased by either improving the function or reducing the cost.

Page 20: Procurement : Resisting price increase

VE (structured thought process to evaluate options as follows)

Gather information ⁻ What is being done now?

⁻ Who is doing it?

⁻ What could it do?

⁻ What must it not do?

Measure ⁻ How will the alternatives be

measured?

Analyze ⁻ What must be done?

⁻ What else can perform the desired function?

⁻ What does it cost?

Generate ⁻ What else will do the job?

Evaluate ⁻ Which Ideas are the best?

Develop and expand ideas ⁻ What are the impacts?

⁻ What is the cost?

⁻ What is the performance?

Present ideas ‒ Sell alternatives

Page 21: Procurement : Resisting price increase

Vendor development

• Procuring organization forms a team of engineers and

assign it to their suppliers for carrying out the specific

development projects.

• By having the direct support of their client and regular

monitoring of their development

– will be more motivated to carry out the program fully &

– will readily realize that the program is indispensable.

Page 22: Procurement : Resisting price increase

• Points to remember

– Negotiate the Supplier's Entire Volume not only for your

requirement but also for his other customers need.

– The larger the volume , the greater your savings.

– Always Manage The Negotiations.

• You may have the knowledge and technology to

manage the negotiations better than the supplier.

– This also gives you the control on timeline, information on

inputs, etc.

Negotiating on behalf of your subcontractor

to avail lower costs

Page 23: Procurement : Resisting price increase

ISO 9000 / TS 16949 certification ----

• ISO 9000 certification stresses the importance of

compliance on technical specifications and the quality

requirements .

• In fact , some procuring enterprises agree to work with

suppliers only if they are ISO 9000 certified.

• To help subcontractors acquire such certification, main

contractor should assist them with regard to system &

procedures to be adopted for

• documentation control

• product purchasing

………………..

Page 24: Procurement : Resisting price increase

Total quality (zero defects) management

• Detect defective components and diagnose the

causes of such defects

• Reduce waste and reworking

• Build up expertise

• Review the importance of quality in the budget

• Develop a culture centered on the workers’

accountability for quality and

• show them what they can gain in terms of personal

satisfaction and security.

Page 25: Procurement : Resisting price increase

Allowing use of main contractors’ production

facilities by subcontractors …

Subcontractor is an extended partner in your supply chain

He should be allowed to have access to main contractors

facilities such as :

– instruments

– moulds

– prototypes

– patterns

– quality control equipment etc which directly

enhance the quality of products.

Page 26: Procurement : Resisting price increase

Organization of work within the

enterprise

• Internal functioning of an enterprise is important from a

quality viewpoint.

• Thus to gain a better appreciation of overall coordination

the organization would need:

– No barriers between different departments / Sections

(Homogeneity between departments)

– Encourage teamwork

– Organize discussions on working practices and

investigate solutions to problems

Page 27: Procurement : Resisting price increase

Objectives of Vendor rating

– To motivate suppliers to improve performance.

– To apportion orders to deserving vendors for overall

cost reduction.

– To select vendors for further development.

– To reduce the cost of inspection of incoming lots by

modifying sampling plan

Supplier reward program

• There are two sides of performance improvement

motivation:

– Rewarding the suppliers who perform well so

they will aspire to continue performing well ,

and

– Correcting Poor Performance : taking

corrective action with those suppliers whose

performance does not meet our expectations.

• It would never be safe to assume that switching

supplier eliminates problems

Page 31: Procurement : Resisting price increase

• With focus on shrunken vendor base ,

• Consolidation with limited few vendors is encouraged

called tier 1 suppliers who in turn take responsibility

for quality of tier 2/3 suppliers

• Suppliers are assured of long term commitments and

cooperative relationship

• Buyers work along with suppliers to develop cost

reduction for both firms

• Suppliers are even allowed to keep certain portion of

the profits thru these joint efforts

Vendor consolidation

Page 32: Procurement : Resisting price increase

Supplier Relationship model (SRM)

Unilateral “Make the best part”

Interactive “Together develop better spec”

Collaborative “Supplier teams make the best system or process.”

Higher Supplier Involvement

Higher Value Addition

Page 33: Procurement : Resisting price increase

1. To improve supplier performance. On cost reduction , OTD , Zero defect , Reduced W/C , prompt service .

2. To reduce risk. . Ensure continuity of supply in the face of unexpected disruption to the operations of one or more suppliers from natural disasters, political upheavals, and other events

3. To provide flexibility and agility to the organization thru’ a healthy vendor base

4. To save money

Conference

Negotiation

Negotiation is therefore a process involving a

conference whereby skillful maneuvering &

compromise are used to achieve an agreement

The time

invested on

negotiation

should yield

tangible results

Page 36: Procurement : Resisting price increase

Ensure early Purchasing Involvement

• Suppliers try to woo the Internal customers to get

insight to the decision making process & other

important information .

• Purchasing professionals are typically trained to uphold

high ethical standards and will ensure that these tactics

are not successfully used by suppliers.

• Purchasing professionals are experts in evaluating the

overall supplier capabilities wrt to financial(Z-score )

,Quality, Technical & Mfg excellence .

• A passion for risk management which other wise may

get ignored ( Succession plan , Tax and duty structure

,overall low cost etc )

Page 37: Procurement : Resisting price increase

Effective Negotiation skills preparation & planning

• Prepare in details for conducting a successful

negotiation

• Bring in more transparency to the process for a long

term relationship

• Remember you’re the expert

• A good negotiation should cover all terms : price,

warranty, delivery, payment terms, etc.

• What often happens is that one supplier offers the

best price, 2nd offers the best warranty, a third offers

the best delivery, etc.

Page 38: Procurement : Resisting price increase

Should A Manager Join A Negotiation In Late

Stages?

While some managers feel their jumping in at a later stage will

squeeze another 5% out of the supplier, the fact is that their

actions result in companies getting worse deals, not better.

• Actually, the supplier may welcome another counterpart -

that way he can play "divide and conquer" and get the

manager to agree to concessions that the buyer would not.

• If past history compels a supplier to predict that a manager

will join a negotiation in its late stages,

• will the supplier ever give its best deal to the buyer ? No -

the supplier will withhold it so that it has something to

offer the manager later.

⁻ Non-Conformances / Corrective and Preventive Action (NC/CAPA)

⁻ Complaint Handling

⁻ Statistical Process Control (SPC) – to get Real-time visibility of supplier quality metrics through web-based portal

• Real-time visibility of manufacturing data helps OEMs eliminate the black box effect of outsourcing critical components.

• It also eliminates surprises on the receiving nonconforming materials.

Flexibility

• Supply chain flexibility is defined as “the ability to quickly respond to changes in demand while achieving your objectives of

– customer service,

– shorter lead time ,

– cost,

– inventory and

– return on assets (ROA)

Page 51: Procurement : Resisting price increase

F-Flexibility measures

• Volume flexibility (Fv ) : measures the proportion of demand that can be met profitably by the supply chain system

• Delivery flexibility (Fd ) :

– The ability to move planned delivery dates forward .

– This ability allows the supply chain to accommodate rush orders and special orders, and will be described as delivery flexibility.

– Delivery flexibility is expressed as the percentage of slack time by which the delivery time can be reduced

• Mix flexibility (Fm ) : the response time between product mix changes.

• New product flexibility (Fn): is defined as the ease with which new products are introduced , the time or cost required to add new products to existing production operations

Delivery flexibility (Fd)

• Delivery dates change regularly and costs are associated with not meeting the delivery dates

• The ability to move planned delivery dates forward may be important in supply chain management.

• This ability allows the supply chain to accommodate rush orders and special orders, and is described as delivery flexibility.

• Delivery flexibility is expressed as the percentage of slack time by which the delivery time can be reduced/advanced

Six Sigma • Every mistake an organization or person makes ultimately has

a cost,

– the need to do a certain task over again,

– the part that has to be replaced,

– time or material wasted

• You consume additional resources to correct a problem before it's delivered to the customer

• Six Sigma is a scientific problem solving tool for

– meeting your customer's needs (Time , speed , Quality )

– minimizing wasted resources (Errors , rework , Hidden factory , variations +/-)

– maximizing profit in the process ,thru’ disciplined data

collection and analysis to determine best solutions

Page 58: Procurement : Resisting price increase

Six Sigma focus

• The goal of Six Sigma is to inject

– disciplined control,

– predictability, and

– consistency of results

so that the product comes off the production line absolutely

consistently.

• The methodology of Six Sigma was first applied in a

manufacturing company, but is extensively used in service

and transactional companies (like banks and hospitals),

• Six Sigma initiatives and projects have a direct measurable

financial focus eg OFR , Quality , Lead time , OTD ,IT , ROI etc

Page 59: Procurement : Resisting price increase

Higher Process Sigma – lower Rejection

• A low process sigma means that a significant part of the tail of the distribution is extending past the specification limit. More defects.

• So the higher the process sigma score Z , the fewer the defects

1. 2σ = 30.8% Rej 2. 3σ = 6.68% Rej 3. 3.4σ = 3% Rej 4. 4σ = 0.62% Rej 5. 5σ = 0.0223% Rej 6. 6σ = 0.0003% Rej

} Most of Indian Industries are here

This is the journey we have to undertake

Page 60: Procurement : Resisting price increase

2 approaches to Improvement DMAIC DFSS

• Six Sigma offers two approaches for improvement

1. Improve the process so that chances of defects are reduced ,ie reduce the standard deviation (increase Z score) thru’ DMAIC

2. Change the design (DFSS) so that product can accommodate process variations

• A Six Sigma process should not generate any flaws , but since , over the long run (Lt Std Dev) , every process shifts by +/- 1.5σ , 3.4 parts of every million may go beyond 6σ level generating few defects

Page 61: Procurement : Resisting price increase

Process capability of a process or characteristic to meet its specifications (VOC/VOP)

1. Capability : Ability to match the voice of your process-VOP to the voice of your customer-VOC

2. The simplest capability index is called Cp.

3. It compares the width of a two-sided specification to the effective short term width of the process.

USL - LSL represents

the VOC-voice of the

customer's

requirements and

Cp

• Cp is known as measure of process capability .

• It is the number of times the spread of the process fits into the tolerance width.

• The higher the value of Cp, the better the process.

Control

• A solution that isn’t sustained over the long term has little value

• Control charts are two-dimensional graph plotting the

– performance of a process on Y axis, and

– time or the sequence of data samples on X axis.

• They are basically a type of Run chart with control limits

Why Control chart

– It shows nature of variation in the process over time

– Helps in detecting changes in the process

– Helps in controlling the process

• Specs : USL/LSL vs UCL/LCL

– CONTROL is also capability , 𝐂𝐩 - Process Capability

Page 64: Procurement : Resisting price increase

Why Controls

1. Process behavior is complex and fragile and that hard-earned gains slip away if the process is left to itself.

2. The Control phase helps you make sure the problem stays fixed, and, if done properly, provides you with additional data to make further improvements to the process.

3. A well designed process exhibits inherent self control, but..

4. A poorly designed process requires frequent external control and adjustment to meet requirements.

5. A process with well built-in control acts like the heating and cooling system in a house: The system automatically maintains a comfortable temperature at all times.

Variable Control Charts

• Variable Control charts are used to monitor measurable quality characteristics of a process eg Temperature , dimension , weight , viscosity etc

• Variable charts can monitor only one quality characteristic at a time .

• For more than one characteristic, a chart for each characteristic needs to be created

• Variable Control charts help to monitor both process mean and process variability

• Hence it becomes necessary to use minimum 2 control charts to study the process. Ie

– Range or Std Deviation

– Process mean , with UCL & LCL

Variable Control Chart - contd

– R Chart / X Chart or

– X / S chart or

– MR / X chart

• An X chart is the most widely used control chart which monitors the sample variability

• The R chart is used when sample size is less than 10

• S chart is used when sample size is greater than 10.

• For quality characteristic with sample size one , moving range needs to be established and hence a MR chart is used.

• As a thumb rule 20 to 25 samples should be selected for analysis with sample size of 4 to 5 .

Sum-up • Last but not least :

• You’ve got to make sure your suppliers understand how you

define Quality and OTD.

– Avoiding this step appears negatively in your cost , and

second

– Your relationship with suppliers is important. You have to

treat them more like partners than suppliers.

The success mantra for getting quality products and

maximizing cost reductions is by working

harmoniously with suppliers as if they’re a trusted

partner

Establish (KPIs) of all related processes and actions to Accelerate Operational Excellence

• It's crucial to identify a specific set of KPIs that will

help you measure progress and identify areas for

adjustment.

• Equally important to having these measures, however,

is a related system of communication procedures,

processes around the KPIs to ensure that they are

being accurately measured, interpreted,

communicated, and acted upon.

Purchasing Ethics

• I believe that the position of Purchase Engineer is

important , honorable , worthy , responsible , and calls

forth the highest ethical principles in relationship and

dealing with men.

• I believe in the ‘square deal’ towards the company I

represent and towards the men with whom I do business

.

• I believe it is my duty to refuse and renounce gifts or

perquisites from those with whom I transact business.
