In such a case, the conformance clause should specify whether or not an implementation is considered to be conformant if it does not implement each approach? In my opinion, as the data requirements on projects become more complex and we strive for more collaboration, it is crucial that everyone has the same basis of project requirements, and this makes specifications as essential now as they have ever been. 0000002922 00000 n Procurement is responsible for final editing of Not all specifications or standards need a testing program. This is costly because much work may have already been done which did not take into consideration and may exclude meeting the later requirements. --------------------------------------------------------------------------------, Lisa J. Carnahan National Institute of Standards and Technology Information Technology Gaithersburg, Md. 136 Conformance vs. for different products. DOM Test Suite - NIST has developed a comprehensive set of tests that will check for compliance with the Document Object Model (DOM) Level 1 Recommendation. Design specifications are an interpretation of what the customer needs. characteristic of equipment, materials and supplies. What are Performance/Output Based Specifications? The alternative is falsification testing, which subjects an implementation to various combinations of legal and illegal inputs, and compares the resulting output to a set of corresponding "expected results." Determining whether a product faithfully implements a standard or specification is essential to creating robust, interoperable solutions. Conformance Specification (Technical) which focuses on inputs and provides specific details of what the product/service should consist of, and how the product should be manufactured as well as what materials and process should be followed. It's important to have several calls/meetings with the requesting department to get more clarity about their needs, ask them to get piece of paper and write on it what they need whatever they can write! Similarly, validation cannot exist without a test suite, but a test suite can exits without validation. 6 What makes a good specification in procurement? MIL-PRF- 19500 (Semiconductors), or MIL-PRF-38535 (Microcircuits)] referenced in the contract. The conformance clause of a specification is a high-level description of what is required of implementations. Software that is tested to ensure that it meets the requirements detailed in the specification can improve the quality of the software and the likelihood of achieving interoperability. at least two brand names that will satisfy the A .gov website belongs to an official government organization in the United States. The sponsor has a fundamental interest in ensuring the success of the program. compliance with specifications, and (4) provide for an equitable and to invite maximum reasonable competition. competition consistent with seeking overall economy for the 1. In recent years, the term conformity has gained international use and has generally replaced the term conformance in ISO documents. 0000003961 00000 n It is the most traditional kind of A good specification should do four things: (1) Identify minimum requirements, (2) allow for a competitive bid, (3) list reproducible test methods to be used in testing for compliance with specifications, and (4) provide for an equitable award at the lowest possible cost. Secure .gov websites use HTTPS When all deviations and omissions are eliminated, the implementation conforms to the specification. Acceptance/rejection of such item needed will be according to the performance stated in the specification With performance specs, it will take more time for the procurement process as you may get totally different proposals and you need to discuss and validate them internally; however it opens the door for innovation as suppliers are free to suggest any workable solution which may improve functionality, cost & to be more sustainable option it's very suitable in case requesting department is not very well established so that you will be depending on suppliers' experience. situations when the use of this specification is our only There are different types of technical or engineering specifications (specs), and the term is used differently in different technical contexts. conformity assessment - any activity concerned with determining directly or indirectly that relevant requirements are fulfilled. `d 0@90@AA= .5@2:6: 12@7 KK;+MD 4p$? k9S:>P("hb YUE#5K>,46SCL- goods or service must perform. should be put on notice that the criteria used to define Conformance tests are meant to provide the users of conforming products some assurance or confidence that the product behaves as expected, performs functions in a known manner, or has an interface or format that is known. Inspections will be conducted on the products at delivery:6.1.1 Any defect on the products.6.1.2 Conformance to specifications and functionality.. Conformance to specifications requires formal data specifications, which may address any or all of data . of Procurement has approved the use. 0000007141 00000 n It, in turn, refers to other parts of the standard. Validation with certification is often used as a prerequisite for procurement. QUALIFIED PRODUCT LIST (QPL): A specifications by bn reviewed by rh this procurement is being solicited as a small purchase request for quotation (rfq). There are two main approaches to handling implementation specific extensions to a standard. For example, American national standard ASQ/ANSI ID1:2021 defines aCertificate of Compliance as adocument from an authority certifying that the supplied products or services conform to specific and required specifications. What does it mean when software conforms to a standard or specification? Ideally, we would like to be able to prove beyond any doubt that an implementation is correct, consistent, and complete with respect to its specification. A conformance test program needs to be supported by an advisory or control board, whose role is to resolve disputes and provide technical guidance. 0000066307 00000 n Specifications are statements of requirements to be satisfied in the supply of a product or service There are two main types of specification when contracting namely: With this type of specification the buyer says what they want and how they want it and the supplier has to meet this Examples of conformance specification are: What are the types of specification in procurement? This is called strict conformance. Product to be packed in this carton box is Shampoo bottles, dimension of 1 bottle is 180mm height x 50mm width & weight of one bottle is 50ml. Requisition 1 provides the buyer with much more scope and freedom (you didn't want chopsticks then?). The conformance clause may specify minimal requirements for certain functions and minimal requirements for implementation-dependent values. The National Institute of Standards and Technology (NIST) and the Organization for the Advancement of Structured Information Standards (OASIS) are addressing XML-related interoperability issues by jointly developing test suites that are intended to complement the W3C Recommendations. Do you have any other example on Conformance & Performance specifications? The term "optional" is used to indicate that if an implementation is going to provide the specified functionality, then the specification must be followed. Supplier Resources. Written by Lewis Hutson - Thank you for taking the time to read my first of hopefully (dependant on the first ones reception)many articles. Accompanying the actual test files is an XML test description file that contains pertinent information for each of the tests included in the distribution. 0000066233 00000 n Dr. W. Edwards Deming is often linked with approaches to improvement that carry labels such as TQM, Six Sigma, and Lean. Procurement serves as the primary competitors that can supply the product, the department head has Although there may be Lets Start by looking at a Procurement functions relationship with Specifications. 2. Departments using design Paper combination is: 3 layers carton (Layer1 is Kraft liner of 125GSM + Layer2 is Test/Recycled liner of 100GSM + Layer3 is Kraft liner of 125GSM) with mentioning Flute type and total GSM. Conformance involves two major components: (1) a test tool and (2) a testing program (e.g., certification or branding). quotation request An official website of the United States government. In many of these cases the problem is not that the scope changed but that the original Specification was incomplete. eliminates, items that are outside the boundaries drawn. brand-name specifications has the effect of limiting the bidding Lock Implementation dependent ranges, minimum or maximum allowed sizes, etc. The main reason a CoC is required at customs is to prove a product that the product being imported meets the required standard(s). The Java test suite contains over 200 tests and covers the fundamental and extended interfaces of the DOM Level 1 Recommendation. In fact, specification writing should begin very early on in a project lifecycle. There are additional advantages when a technical specifications document is drawn up and it forms an integral part of the procurement process and order placement. SPECIFICATION DEFINITIONS AND INSTRUCTIONS. represents the kind of thinking in which architects and engineers The conformance clause is a part or collection of parts of a specification that defines the requirements, criteria, or conditions that shall be satisfied by an implementation in order to claim conformance. this would be prohibitive. The understanding is that an implementation that is determined to satisfy each assertion will be considered to be in conformance to the standard. The conformance testing policies and procedures should be spelled out before testing begins. 2. Each test should lend itself to providing objective, reproducible, unambiguous, and accurate results. 9 0 obj A good conformance clause is the ultimate goal of these guidelines, and is sanctioned by conformance to this specification. Typically, level 1 is the basic core of the specifications that must be implemented by all products. A lock ( Conformance to Specifications. In my personal experience "Completeness" of requirements is the hardest but possibly the most important of the four key characteristics of good Specifications. What steps lead conformance to specification? In some cases, it has to be provided for EVERY part with its own serial number. Taking the time to think, write & challenge what your internal customer need is one of the most important keys to have efficient, smooth, transparent & successful procurement process. The buyer uses the results of the testing to verify that a seller provides a product that conforms to the specification and meet procurement requirements. In these cases, it may be desirable to partition the specifications into subsets of functionality. How many times have you looked at this afore mentioned specification and instantly picked holes in the acheivabilty of the desired outcome? The conformance clause identifies what must conform and how Often times, errors or ambiguities in the specification are discovered. approval for the product offered before bid opening. 0000009297 00000 n The level and formality of the conformance testing is determined by the buyer, an organization acting on behalf of a community of buyers, or by regulation (e.g., safety, health, national security concerns). They often refer to particular documents, and/or particular information within them. Conformance Specification defines requirements when the buyer specifies what they want, how they want it, and the supplier has to meet these specifications. In order to test that a specification is faithfully adhered to, one must carefully examine the specification and compare the implementation's result against the syntax and semantics contained in the specification. There are two main types of specification when contracting namely: #1 CONFORMANCE SPECIFICATION With this type of specification the buyer says what they want and how they want it and the supplier has to meet this Examples of conformance specification are: Engineering drawing A chemical formula Model name, number or brand etc activity involved in developing specifications for items When a requisition does not include an existing standard, specification or purchase description, which the contracting officer considers . of function and cost. Failure to pass a test implies failure to conform. specifications; brand-name-or-equal specifications; design Sometimes, its really challenging to collect/get what your organization need .. even after sending the Tender/RFQ package, suppliers sometimes come back to you and comment Its not really clear for us whats required ? In contrast to the design approach, this sense means that the specification concentrates on how the (b) Semiconductor devices and microcircuits not procured under a military specification shall be An example would be a recipe for a food . If you cant describe what your organization need on piece of paper then imagine how suppliers can understand your needs, then quote/propose the right solution for it. performance specifications afford the manufacturer or bidder BRAND-NAME SPECIFICATIONS: The [1] Gartner Group, a Stamford, CT based consulting company, [2] ISO/IEC Guide 2:1996, Standardization and Related Activities General Vocabulary, Webmaster | Contact Us | Our Other Offices, Created September 8, 2010, Updated August 25, 2016, Manufacturing Extension Partnership (MEP). Performance responsibilities focus on strategy, value creation and resource utilization whereas conformance responsibilities focus on providing assurance to stakeholders that the organization . Falsification testing can only demonstrate non-conformance. Although the terms validation and conformance testing are often interchanged, they are not the same.

The rationale for an expiration date is that the technology, test suite, and/or specification will probably change and this forces the implementation to be retested. The ECMAScript suite allows the user to select a category of tests from a drop down menu. is less interested in dimensions and materials and configurations Please tell me by leaving a comment. Moreover, each test should be written so as to explicitly state the behavior of a conforming implementation. Conformance to requirement or specification: that is, the product matches the features, attributes, performance and standards set out in the specification Acceptable quality and value for. DEVELOPING SPECIFICATIONS: Although Requirements Work that matches what was requested in requirements. by vendors to add products to the QPL. The decision to establish a program is based on the risk of nonconformance versus the costs of creating and running a program. QualityInspection.org does not present this information as a basis for you to make decisions, and we do not accept any liability if you do so. Although policies and procedures are not issues for the standard specifications, the standards body may be involved in their development. 2. It here unfortunatley all to often a stage where procurement are left out and not involved from the very begining stages. It is generally inspected during customs clearance if the product being imported requires it. There must be sufficient basis to determine that these Do you have any questions or experiences to share about certificates of conformity? 0000007164 00000 n sound evaluation criteria. How To Manufacture A Product In China (without losing your shirt)? However, this is generally impossible for implementations of nontrivial specifications that are written in a natural language. We want to make it easy to do business with us while also helping you navigate the regulations involved in the aerospace and defense technology sector. Some standards have subsequent documentation for the test methodology and assertions to be tested. It should be possible to know where the Specification originated. It should be possible to know by observation of the finished system/product that the requirement has been met. What are the purpose of specification in procurement? Reference method tests and PEMS drift tests are conducted to determine conformance of the PEMS with the specification. Conformance testing provides software developers and users assurance and confidence that the conforming product behaves as expected, performs functions in a known manner, or possesses a prescribed interface or format. If you do not use a third party laboratory, you may label this section N/A. If the mattresses being certified are for cribs or childrens size mattresses, please see the requirements for issuing a CPC.

This test suite has been used on a variety of XML processors, and results have been published on XML.com. performance, quality or essential characteristics must be It also provides an independent, objective method for evaluating similar products and ensuring that software customers are not locked into purchasing a software product from a single vendor. 2) Actions - related to things such as functions, processes, ,procedures, services, performance. items regularly available in the market place, as is Though there are so many things that make a good well rounded specification im going to narrow it down to 4 simple factors; There should be only one way to interpret the requirements of the customer. purchased under indefinite quantity term contracts and definite Using this set of TAs, a set of tests that will exercise each of the requirements is developed. A reference implementation is an implementation of a standard that is by definition conformant to that standard. The ECMAScript test suite contains over 800 tests and covers the fundamental, extended, and HTML interfaces of the DOM Level 1 Recommendation. 0000010532 00000 n have been trained. Buyer requires conformance to the Specification. 1.2 Upon request by the Owner, the Manufacturer at its expense shall provide proof of conformance with any or all requirements of this specification. Performance requirements describe the characteristics and Developers/Customers often complain that Scope Creep occurred during a project. Any other brands or models 0000007885 00000 n 0000009860 00000 n To illustrate the characteristic of Completeness in Specifications consider my proposed user requirements for a new car. broad groupings are more particular types, including: brand-name ISO/IEC Guide 2[2] defines conformance (also referred to as conformity) as the fulfillment of a product, process, or service of specified requirements. A certificate of conformity, or CoC, is issued by an authorized party (sometimes the manufacturer, sometimes an independent laboratory) and states that the product meets the required standards or specification. What should a certificate of conformity include? Depending on the nature of the electronic device being imported, you will either need to go through a more comprehensive FCC certification or can submit your own Suppliers Declaration of Conformity. Lets look at the difference between the two: For RF Devices with the greatest potential to cause harmful interference to radio services like smartphones, Bluetooth speakers, earbuds, etc, that emit radiation a self-declaration is not acceptable to comply with FCC regulations and they must be certified by an FCC-recognized Telecommunication Certification Body (TCB) based on an evaluation of the supporting documentation and test data submitted by the responsible party (e.g., the manufacturer or importer) to the TCB. When does a buyer ask the supplier for a CoC? This free eBook shows importers who are new to outsourcing production to China or Vietnam the five key foundations of a proven Quality Assurance strategy, and also shows you some common traps that importers fall intoandhow to avoid or overcome them in order to get the best possible production results. Click here for Terms & Conditions. "Design" in Unfortunately, we have no experience in this topic, and the requirements vary from one country/area to the other, so we are unable to help. My company Sofeast, can probably help you. Conformance means that a product meets the minimum requirements in the standard. Furthermore, what is a conformance specification? Conformance testing (also called conformity assessment) is a way of verifying implementations of a specification to determine whether or not deviations from the specification exist. Certain countries request a CoC for certain categories of imported products. The alternative is falsification testing, a strategy that results in a level of confidence that an implementation conforms. Identify minimum requirements, (2) allow for a competitive bid, The documentation should be detailed enough so that testing of a given implementation can be repeated with no change in test results. I will be discussing topics covering all aspects of the Supply chain (particularly Procurement) fuctions, Change Managment ideas and theories and IT software solutions (General focus being ERPSystems such as INFOR M3)For business needs. /Length 10 0 R The developers might respond that those were not part of the requirements and this would be scope creep to the project. requirements. 1.3 Upon request by the Owner, the Manufacturer at its expense shall provide, a https://www.nist.gov/itl/ssd/information-systems-group/what-thing-called-conformance. The conformance clause of a standard specification is a high-level description of what is required of implementers and application developers. characteristics of the item desired. Supplier Resources. Conformance is how well realities match specifications, rules, principles and plans. The conformance clause is a part or collection of parts of a specification that defines the requirements, criteria, or conditions that shall be satisfied by an implementation in order to claim conformance. 0000006359 00000 n 4M%m8Kxq@D0P- E62e(S4O#?s3,!Ms%iTZa5 @!.MOzNRU!+9nI For example, some testing programs may require a very formal testing and certification approach using an independent (i.e., third party), nationally accredited testing laboratory while other programs may be more appropriate for self declaration and demonstration testing. developing your specifications, however, Procurement does not a. Deviation in delivery period shall be considered if such deviation is reasonable.6.1. If errors are found, one can correctly deduce that the implementation does not conform to the specification; however, the absence of errors does not necessarily imply the converse. Conformance and Performance Specifications 1. It increases a buyer's confidence in a product and its ability to meet their needs. need. 0000002442 00000 n R3XF5h{o9gkz1p!i[$KQt?I$o:hdSisA4e3Dm9,Hhj4@`h$&!!r" BH$@4$"Jz"H,*Mc18/,1 #c7n~ "/[#J The validation process consists of the steps necessary to perform the conformance testing by using an official test suite in a prescribed manner. This type of conformance testing makes use of publicly available test suites or tools and is not associated with any formal validation or certification program. A defect can lead to a failure that might result in loss of life. Extensions shall not re-define semantics for existing functions, Extensions shall not cause standard-conforming functions (i.e., functions that do not use the extensions) to execute incorrectly, The mechanism for determining application conformance and the extensions shall be clearly described in the documentation, and the extensions shall be marked as such. products, others may simply require that brands be tested under Here is one example. What we wrote above is based only on our understanding of the regulatory requirements. Procurement professionals should be focusing on what type of specification they are sharing with suppliers and to guide their internal customers to draft their specification document according to that. j.h8 Also, what is the difference between conformance specification and performance specification? BRAND-NAME-OR-EQUAL SPECIFICATIONS: A 0000009883 00000 n products before soliciting competitive bids. What is the difference between conformance specification and performance specification? The test suite will focus on XSL transformations (XSLT) and XML Path Language (XPath). contracting for buildings, highways, and other public works, and Performance purchasing is results orientated in terms The CoC is sometimes called Certificate of Conformance or Certificate of Compliance. Specifications sometimes need to address: Specifications may describe several different ways to accomplish its operation (e.g., a choice of file formats or codes). The specification must: Be set out in the relevant Procurement Documents clearly describe what is required detail the characteristics required not refer to the following: brands or trade names a. or other required characteristics should be clearly This bulletin presents an overview of conformance and addresses conformance to the World Wide Web Consortium (W3C) Recommendations for the Extensible Markup Language (XML) family of specifications. Falsification testing can only demonstrate non-conformance. The main reason a CoC is required at customs is to prove a product that the product . It may also be called a certificate of conformance or certificate of conformity.. interchangeably to designate an approach to specifications that At last the month and year should be shown and the city, state, and country needs to be shown. is characteristic of construction or personal services contracts. Validation is the process of testing software for compliance with applicable specifications or standards. Early supplier involvement can reduce evaluation time in performance based contracts. An airline buys fan blades for their planes engines. 0000069347 00000 n A lock ( Examples of conformance specification; The conformance clause is a part or collection of parts of a specification that defines the requirements, criteria, or conditions that shall be satisfied by an implementation in order to claim conformance. Well also examine in more detail the type of CoC you need to import consumer and electronic products into the USA and EU, as well as covering some other points on the topic, too. Certification is the acknowledgment that a validation has been completed and the criteria established by the certifying organization for issuing a certificate, has been met. FCC (47 CFR Section 2.906) again states that the SDoC is: a procedure that requires the party responsible for compliance ensure that the equipment complies with the appropriate technical standards. A specification is often a type of technical standard. The CoC can either be requested by a buyer to ensure the product being manufactured has been tested and passes the set criteria within a specification and meets both technical and safety requirements,or it would be a mandatory requirement as stated by country regulations and law for certain products, such as Bluetooth devices being sold in the USA. If such a list is provided, the starting point for the development of the test suite is the list of assertions for the standard. Does it come from a particularly influential stake-holder? If the criteria or requirements for conformance are not specified, there can be no conformance testing. Operational teams view quality in terms of conformance to specifications. Generically, a conformance test suite is a collection of combinations of legal and illegal inputs to the implementation being tested, together with a corresponding collection of "expected results." 6. A profile is a subset of the overall specifications that includes all of the functionality necessary to satisfy the requirements of a particular community of users. They can also be selected from a drop down menu, executed and results displayed.
