The document discusses key aspects of quality management and inventory management from a procurement perspective. It covers four factors that determine quality levels, such as appropriate specifications and monitoring suppliers. Quality is defined in terms of performance, reliability, and conforming to requirements. Total quality management requires customer satisfaction and continuous improvement. Inventory exists to satisfy demand and prevent stockouts, but excess inventory incurs carrying costs. Managing inventory levels, order quantities, and reducing variability can lower costs.

Memorandum Of Association Constitution of Company.pptseri bangash
www.seribangash.com
A Memorandum of Association (MOA) is a legal document that outlines the fundamental principles and objectives upon which a company operates. It serves as the company's charter or constitution and defines the scope of its activities. Here's a detailed note on the MOA:
Contents of Memorandum of Association:
Name Clause: This clause states the name of the company, which should end with words like "Limited" or "Ltd." for a public limited company and "Private Limited" or "Pvt. Ltd." for a private limited company.
https://seribangash.com/article-of-association-is-legal-doc-of-company/
Registered Office Clause: It specifies the location where the company's registered office is situated. This office is where all official communications and notices are sent.
Objective Clause: This clause delineates the main objectives for which the company is formed. It's important to define these objectives clearly, as the company cannot undertake activities beyond those mentioned in this clause.
www.seribangash.com
Liability Clause: It outlines the extent of liability of the company's members. In the case of companies limited by shares, the liability of members is limited to the amount unpaid on their shares. For companies limited by guarantee, members' liability is limited to the amount they undertake to contribute if the company is wound up.
https://seribangash.com/promotors-is-person-conceived-formation-company/
Capital Clause: This clause specifies the authorized capital of the company, i.e., the maximum amount of share capital the company is authorized to issue. It also mentions the division of this capital into shares and their respective nominal value.
Association Clause: It simply states that the subscribers wish to form a company and agree to become members of it, in accordance with the terms of the MOA.
Importance of Memorandum of Association:
Legal Requirement: The MOA is a legal requirement for the formation of a company. It must be filed with the Registrar of Companies during the incorporation process.
Constitutional Document: It serves as the company's constitutional document, defining its scope, powers, and limitations.
Protection of Members: It protects the interests of the company's members by clearly defining the objectives and limiting their liability.
External Communication: It provides clarity to external parties, such as investors, creditors, and regulatory authorities, regarding the company's objectives and powers.
https://seribangash.com/difference-public-and-private-company-law/
Binding Authority: The company and its members are bound by the provisions of the MOA. Any action taken beyond its scope may be considered ultra vires (beyond the powers) of the company and therefore void.
Amendment of MOA:
While the MOA lays down the company's fundamental principles, it is not entirely immutable. It can be amended, but only under specific circumstances and in compliance with legal procedures. Amendments typically require shareholder

Enterprise Excellence is Inclusive Excellence.pdfKaiNexus
Enterprise excellence and inclusive excellence are closely linked, and real-world challenges have shown that both are essential to the success of any organization. To achieve enterprise excellence, organizations must focus on improving their operations and processes while creating an inclusive environment that engages everyone. In this interactive session, the facilitator will highlight commonly established business practices and how they limit our ability to engage everyone every day. More importantly, though, participants will likely gain increased awareness of what we can do differently to maximize enterprise excellence through deliberate inclusion.
What is Enterprise Excellence?
Enterprise Excellence is a holistic approach that's aimed at achieving world-class performance across all aspects of the organization.
What might I learn?
A way to engage all in creating Inclusive Excellence. Lessons from the US military and their parallels to the story of Harry Potter. How belt systems and CI teams can destroy inclusive practices. How leadership language invites people to the party. There are three things leaders can do to engage everyone every day: maximizing psychological safety to create environments where folks learn, contribute, and challenge the status quo.
Who might benefit? Anyone and everyone leading folks from the shop floor to top floor.

This article provides a comprehensive guide on how to
effectively manage the convert Accpac to QuickBooks , with a particular focus on utilizing online accounting services to streamline the process.
2. Determinants for Quality
Four factors determine the long-run quality
level of a firm’s purchased materials:
• Appropriate specifications for quality
requirements
• Selection of right suppliers
• Realistic understanding with suppliers of
quality requirements and creation of the
motivation to perform accordingly.
• Monitoring of suppliers’ quality/cost
performance
3. Purchasing and quality control
For every transaction between customer and
supplier, they need to agree on:
the basic requirements of the transaction.
the way in which the requirements are to be
realized.
how to check that the requirements are
(being) fulfilled.
the measures to be taken when the
requirements/expectations are not met.
4. Quality, Suitability and
Reliability
What is Quality:
Quality in the simplest sense, refers to the ability of the supplier to provide
goods and services in conformance with specifications. Or performs in actual
use to the expectations of the original requisitioner, regardless of conformance
with specificatiions.
We speak of a quality product or quality service when both supplier and
customer agree on requirements and these requirements are met.
Suitability:
Suitability refers to the ability of a material, good, or service to meet the
intended functional use. In a pure sense, suitability ignores the commercial
considerations and refers to fitness for use.
Reliability:
Reliability is the mathematical probability that a product will function for a
stipulated period of time.
From procurement stand point, Penalties or premiums may be assessed for
variation from design standard depending on the expected reliability impact.
5. Quality Dimensions
Close cooperation between buying and selling organizations can overcome quality
problems which stem from goods and services supplied by suppliers.
Quality is a complex term, has at least 8 dimensions.
1. Performance: the primary function of the product or service.
2. Features: the requirements.
3. Reliability : the probability of failure within a specified time period.
4. Durability. The life expectancy.
5. Conformance: The meeting of specifications.
6. Serviceability: The maintainability and ease of fixing.
7. Aesthetics: The look, smell, feel and sound.
8. Perceived quality: The image in the eyes of the customer.
From a procurement point of view, the ninth dimension should be “procurability” –
the short – and long-term availability on the market at reasonable prices and
subject to continuing
6. The cost of quality
30 to 40 per cent of final product cost may be
attributable to quality.
1) Prevention costs - the costs of preventing quality errors
2) Assessment costs - the costs related to the timely recognition of
quality errors
3) Correction costs - the cost that result from (rectifying) mistakes
Internal error costs: result from mistakes noticed in time
External error costs: are result of flaws identified by the
customer
7. Quality Assurance
Quality assurance concerns keeping methods and procedures of quality control
up to date
The purpose of supplier quality assurance is improvement of supplier quality in
the broadest sense, including environmental and sustainability aspects.
Quality assurance group plays a key role in supplier certification.
SUPPLIER CERTIFICATION:
Quality Assurance survey (supplier’s equipment, facilities , personnel , systems)
on the supplier’s premises - to ensure that the supplier is capable of meeting
the specifications and quality standards required
Methods for assessing a supplier’s capabilities:
Product audit
Provides an image of the degree in which a company succeeds in making
everything run perfectly by inspecting final products.
Process audit
A systematic investigation of the extent to which the (technical) processes are
capable of meeting the standards.
Systems audit
Compares the quality system to external standards (e.g. ISO 9000)

9. TOTAL QUALITY MANAGEMENT
(TQM)
Total quality management --- a philosophy and system of management focussed
on customer (internal or external) satisfaction. . customer can be and is any
one in the supply chain who receives materials from a previous step in the
chain.
Four important features of TQM are:
• Quality must be integral throughout the organization’s activities with
committed and involved management.
• There must be employee commitment and empowerment to continuous
improvement supported by performance measures..
• The goal of customer satisfaction and the systematic and continuous
research process related to customer satisfaction, drives TQM systems.
• Suppliers are partners in the TQM process.
For TQM to work, all stages in the production process must conform to
specifications that are driven by the needs and wants of the end customers.
All processes, those of the buyer and the suppliers, must be in control and
possess minimal variation to reduce time and expense of inspection.
TQM involves the use of tools, such as Continuous Improvement, quality
function deployment (QFD) and statistical process control, to achieve
performance improvements.
10. Continuous Improvement
Continuous improvement, sometimes called by its Japanese name, kaizen, refers to
the relentless pursuit of product and process improvement through a series of small,
progressive steps. Continuous improvement should follow a well-defined and
structured approach and incorporate problem-solving tools such as
Pareto charts—used to distinquish between criticakl and trivial problems
Cause and effect diagrams(fish bone diagram)----possible causes of a problem
through brain storming to identify cause of defects
Process flow charts---for identifying bottlenecks and non value added activities.
Run pilots-to idntify whether process is subject to change or behaves consistently
over time
Frequency histograms-shows the istribution of some variables that is thought to be
important
Scatter diagrams----show correlations between two variables typically the problem
and potential cause
11. QUALITY FUNCTION
DEPLOYMENT (QFD)
The four integrated stages of the QFD process are:
Product planning, to determine design requirements,
Parts deployment, to determine parts characteristics.
Process planning, to determine manufacturing requirements.
Production planning, to determine production requirements.
Using the QFD methodology, buyer and supplier integration into the process can
benefit the organization by
(1) reducing or eliminating engineering changes during product development
(2) reducing product development cycle time, (
3) reducing start-up cycle time,
(4) minimizing product failures and repair costs over the product life and
(5) creating product uniformity and reliability during production.
12. Quality Control:
Quality control: making sure that the requirements are met and being able to
demonstrate this objectively.
Process Control:
Statistical quality control.
Process capability refers to the ability of the process to meet specifications
consistently. Statistical process control (SPC) is a technique that involves
testing a random sample of output from a process in order to detect if non-
randum changes in the process are occurring.
Control charts-----upper and lower limits of process variable help in monitoring
the process
Six sigma
Sampling.
Sequential Sampling.
.
13. Inspection and Testing
Inspection and testing ----- done at two different stages in the acquisition
process.
1, Before commitment is made to a supplier,
Testing and Samples: Use of samples to test for intended purpose and
Laboratory Tests to ascertain conform ation to specific values of parameters.
2. After a purchase commitment has been made,
inspection may be required to ensure that the items delivered conform to the
original description. The type of inspection, its frequency and its thoroughness
vary with circumstances.
In setting specifications, it is desirable to include the procedure for inspection
and testing as protection for both buyer and seller.
Adjustments and Returns: The actual decisions as to what can or should be
done with material that does not meet specifications is both an engineering and
a procurement question.
15. What is Inventory?
Inventory is in the form 1. raw material, ,Finished/purchased parts, 2. Work in
process, 3. Finished goods, Consumables, 4.MRO items /Spare parts 5. resale
items, that are held at a location in the supply chain.
Independent demand – finished goods, items that are ready to be sold.. a
computer
Dependent demand – components of finished products.. parts that make up the
computer
Inventory is one of the biggest corporate assets.
One of the major areas of cost leaks is in the area of Inventory Management.
To increase profits,It is important to plug cost leaks before they become cost
holes.
It is sometimes true that a company loses more on non-availability of materal
despite high inventory investment.
Inventory control is a goldmine for saving. Understanding where (and why)
inventory should be positioned in the supply chain can improve customer
service, lower total costs, or increase flexibility
16. Why Inventories?
• To gain economy in purchasing
--ordering cost / set up cost minimisation
-- to avoid frequent order.
• Hoarding to prevent future price increase.
• To satisfy demand during period of replenishment.
• To carry reserve stocks to avoid stock out.
• To stabilise production and ensure smooth flow of goods through the
productive process :
- Seasonal demand vendors
- Peak and through of demand to be managed
- To levelise resource allocation
• To prevent loss of sales.
• To satisfy other business constraints.
- Condition of minimum order
- Seasonal availability.
• To provide and maintain good customer service.
17. Classification of inventory functions
Transit or pipeline inventories ---to stock the supply and distribution
pipelines linking an organization to its suppliers and customers as well as
internal transportation points.In just-in-time (JIT) production, the use of local
suppliers, small batches in special containers and trucks specifically designed
for side loading in small quantities used to reduce transit inventories.
Cycle inventories ----to purchase, produce or sell in lots rather than
individual units or continuously.
Buffer or uncertainty inventories or safety stocks ---to address variability
in demand . efforts to may have substantial payoffs in reduced inventories. ----
increasing supply alternatives, using local sources, reducing demand
uncertainty, reducing lead time or having excess capacity can reduce supply
variability ------ should be determined by balancing carrying cost against stock
out cost.
Anticipation or certainty inventories are accumulated for a well-defined
future need.
Decoupling inventories make it possible to carry on activities on each side of
a major process linkage point independently of each other.
18. COSTS OF INVENTORIES
For every items carried in inventory, the costs of having it must be less than the
costs of not having it. Inventory exists for this reason alone.
Carrying, holding or possession costs include (1) capital costs(cost of
storage facilities , equipment to handle inventory), (2) inventory service
costs,(handling charges ,storage rentals, labour, and operating costs; insurance
premiums) (3) storage space costs and (4) inventory risk costs.(breakage;
pilferage; obsolescence)
Ordering or purchase costs include the managerial, clerical, material,
telephone, mailing, fax, e-mail, accounting, transportation, inspection and
receiving costs associated with a purchase or production order.
Setup costs refer to all the costs of setting up a production run.
Stock out costs are the costs of not having the required parts or materials on
hand when and where they are needed. They include lost contribution on lost
sales (both present and future), change over costs necessitated by the shortage.
Variations in delivered costs are costs associated with purchasing in
quantities or at times when prices of delivery costs are higher than at other
19. Indicators of poor Inventory
Management
• Stock on hand is high compared to lead time * average consumption
• Frequent stock outs
• Backlog of orders or frequent failure of delivery commitments of high turn
over of customers due to cancellations.
• Uniform inventory policy to different items
• Adhoc policy on minimum stock maintenance
• Uneven production with frequent lay offs and over time working or break
down due to
• Non-availability of spare parts.]
• Discrepancies in stock counts.
