Quality is of paramount importance, especially when the consumer has a plethora of options at his or her disposal. Using Quality Assurance and Quality Control in conjunction with one another and developing a consistent feedback loop can help in identifying the root causes of defects and thereby allow teams to develop strategies that can entirely eliminate these problems at the development stage itself and achieve high-quality products. Based on our combined 450 years of GIS data experience with countless different systems and processes, that’s what we’ll answer here and in future posts on building and maintaining quality. Additionally, regulatory bodies are demanding accountability on the part of the utility operator, driving the need for complete and accurate facility data to support justifiable decision making. circumstances for each country, activities related to QA/QC may be assigned to third parties or consultants, but the plan, integration, and review of these QA/QC activities need to have oversight from the preparing agency. Verification. QA is constantly mixed up with QC “QA” and “QC” are often used interchangeably. Quality Assurance (QA) and Quality Control (QC) are collaborated in all organizations but they are different from each other the difference is that quality assurance activities are proactive and intended to prevent the production of defected products. Not only does it work, but is consistently followed by the team. Quality control activities are reactive as it intended to detect and block defected products using inspection and testing mechanisms. But Quality Control, this in-process focus, isn’t enough by itself. Ideally, QC encourages a way of thinking on the part of those involved in a process: how can we make this better or more efficient? ©2020 SSP Innovations, LLC | 6766 S. Revere Parkway Suite 100 | Centennial, Colorado 80112 |. So what is the difference?I’m glad you asked.Allow me to say that I have no interest in what Webster’s or the Oxford English Dictionary has to say on the matter. Quality pervades all aspects of your GIS, good, bad or somewhere in the middle. Required fields are marked *. Can documentation be produced to make our results more consistent? Your email address will not be published. However, more than anything else at SSP Wind Lake, we do data! In addition to millions of mainstream gas and electric features, we’ve converted: As well as, a whole variety of other datasets from paper and other sources to GIS. That’s where Quality Assurance comes in. The main purpose of the quality control process is ensuring that the software product meets the actual requirements by testing and reviewing its functional and non-functional requirements. Quality Assurance gives you a score. While both QA and QC can be considered two sides of the same coin when it comes to managing quality, they are not one and the same thing. Principles of QC and QA are poorly understood by many companies. QA/QC is the combination of quality assurance, the process or set of processes used to measure and assure the quality of a product, and quality control, the process of ensuring products and services meet consumer expectations.. Quality assurance is process oriented and focuses on defect prevention, while quality control is product oriented and focuses on defect identification. Obviously, focusing on the quality of something you are building, like GIS data, while you are building it, will certainly improve the results.

For example, ArcFM™ is the registered trademark of Schneider Electric, and no endorsement of SSP Innovations or its products and services is expressed or implied by the mention of ArcFM™ in this website and blog. Quality Assurance is a post-process activity which is undertaken to verify and measure the quality level of the output from a process. Kadakia A(1), Joyner B(1), Tender J(2), Oden R(1), Moon RY(3). In summary, Quality Control and Quality Assurance go hand-in-hand as part of an overall quality management program. Maybe it’s a better tool to catch a certain type of error at its source. Good Practice Recommendation: Assignments for QA/QC responsibility should cover all source categories included in the inventory. Conclusion Mohammed Imran . Reply. What does this mean to you and your GIS? The aim of QA is to ensure that the development team is doing the right thing at the right time and in the right way. Quality Assurance is a post-process activity which is undertaken to verify and measure the quality level of the output from a process. Maybe its additional training (for certain individuals or everyone involved in the process). The QC department is responsible for testing the end product and verifies that there are no discrepancies between the product requirements and its final implementation and that the end product performance is optimal. QA is focused on a strategy of prevention and hence is more focused on planning, documenting and setting guidelines for product development to ensure a desired quality of the product.

The focus on QC, on the other hand, is only on the product and not necessarily on the development process. Focus on process improvements to enhance quality, then measure to see how well they worked. As we’ve talked in a previous post about the Definition of Quality, with these 2 terms exist the same “issue” where every single person/organization defines Quality Assurance (QA) and Quality Control (QC) in a bit different way. To begin with, let’s understand the roles of QA and QC. Quality Control is about doing things in-process to produce quality results; it’s about doing whatever can be done to force quality into a process. You may have noticed in all these examples that we have one level of QA (with individuals and teams checking the work they produce), followed by two or more levels of QC. We’ll also dig a little deeper into some specific practices that we have employed over the years that have proven very successful in furthering overall data quality. References: ACR, American College of Radiology (2017). Quality control activities are focused on the deliverable itself. The issues are aggravated in resource-limited settings where QC and QA functions are merged and/or performed by the same individuals. Having listed out the key difference between QA and QC, it is also important to note that these two are equally important parts of a quality management system and ultimately have the same goal – to ensure a great quality, optimally performing product. Well, the opposite is also true: Everything that precedes a QC review is, from the perspective of that QC reviewer, QA. Clearly, quality issues are a huge business risk, because of which there has been an increased emphasis on Quality Assurance and Quality Control. Author information: (1)Children's National Health System, Washington, DC, USA. So QA is based on engineering processes that guarantee quality in more efficient way than QC. QA is more of a process-oriented approach, on the other hand, QC is a product-oriented approach. Thanks for reading! Unless otherwise specified, no association between SSP Innovations and any trademark holder is expressed or implied. The orthogonality of the latter to pi may always be guaranteed . Quality assurance (QA) makes sure engineers are following processes to reduce future bugs, and write code more efficiently. Designing quality plans, conducting inspections, identifying defect tracking tools and training the responsible team in the defined processes and methods fall within the purview of Quality Assurance. I would like to hear back from others on your opinion regarding this subject and provide feedback on why you feel it's important that QA is an independent department, or why you feel it should NOT be. Thus all people who are responsible for product development are responsible for QA. they do not depend on pa. We emphasize that it is only the projection βiFi of Fi which is expanded in a power series, not the force itself. Many people assume that QA and QC are similar in some way. QC activities are more focused on defect detection and verifying the product output against the desired quality levels. As to the question in the title, the answer is a resounding “Yes! QC engineer = Quality control engineer. 5 Quality control and quality assurance are two components of quality management. A QC is an integral part of QA B QA is an integral part of QC C QA and QC are independent to each other D QC may or may not depend on QA QC/QA tests in CT: A radiographer’s / radiological technologist’s guidance chart ... 4 Frequency of QC tests may depend on local, regional or national requirements and/or departmental policy and/or as quoted on manufacturer’s operator’s manual. It is because of this that QA activities are undertaken at the inception of the project and have to ensure that software specifications meet the company and industry standards. Testing is able to detect the major amount of bugs in the product but this doesn’t mean that these defects won’t take place again. Native Apps, Hybrid Apps, or Progressive Web Development. Thanks for sharing the information and it is very useful. Thanks for the publish great ideas in this blog! QC does not control quality, rather it measures quality. So how can you influence the quality of your utility’s GIS in a positive way? Breastfeeding in African Americans may not depend on sleep arrangement: a mixed-methods study. QC personnel may perform quality assurance tasks if and when required.

The fact is that these two terms represent separate processes that may or may not coincide. Validation or … The quality of the data within a GIS has always been important, but never more so than now. arXiv:gr-qc/0112025v3 4 May 2002 Quasi-Metric Relativity by Dag Østvang Institutt for Fysikk, Norges teknisk-naturvitenskapelige universitet, NTNU N-7491 Trondheim, Norway Abstract This is a short survey of a new type of relativistic space-time framework; the socalled quasi-metric framework. Using the same QC rule and QC target on a group of instruments testing the same analyte may seem not to be properly controlling each instrument, but that thinking stems from a QC focus on the instrument. All trademarks remain the property of their respective owners. The scope of QA can be said to be more in the process of development rather than on the product itself. Difference between quality assurance and quality control – Quality Assurance vs Quality Control. We’ll address “field feedback” and how you can encourage field personnel to provide data updates when the GIS is incorrect. I’d actually prefer if the acronym was QC/QA, because in my mind, that’s the proper order. Furthermore, as GIS data becomes more widely available within a utility, we’ve become increasingly dependent upon that data and its overall reliability. The outcomes of the QA/QC process may result in a reassessment of inventory or source category uncertainty estimates. Good QA is dependent on QC, since the information from inspection is necessary to implement corrective and preventive measures. Learn how your comment data is processed. QA defines all the planned and systematic activities implemented before samples are collected, to provide confidence that a … testing to gauge one or more characteristics of a product or service and the comparison of these with specified requirements to determine conformity First of all, it would do you well to realize that “prevent this” is not a plan.

For example, if data quality is found to be lower than previously thought and this situation cannot be rectified in the timeframe of the current inventory, the uncertainty estimates ought to be re-evaluated. QC is a line function that is product or project specific and involves activities such as testing and conducting reviews to identify defects in the final product. Can the process be improved so that I get what I need sooner? It is not looking nice. Both are complimentary to each other and required at every step of testing. “QA” sound smarter than “QC”, so QA is frequently substituted to QC. Practically speaking, when we’re talking about GIS data, QC would include things like: A complete list for your situation might be very different and would likely be much longer. 3. Testing for the purpose of quality doesn’t assure quality, it only controls it. Many organizations either use the two terms interchangeably, or do not have a clear distinction between the two aspects of quality.

It is done through Inspections. One deals with identifying defects and other with preventing them. Having the GIS Technician run a trace on the data they’ve just added to the GIS, Limiting attribute values to specified domains or ranges whenever possible. Quality is relevant to every dataset, to every service, to every customer interaction and that’s just as true for your internal data, services and customers as it is for ours when we’re working with a client. Of course, this stands for Quality Assurance/Quality Control, but what does this really mean? The role of QA is to re-engineer the system so that further occurrence of these defects won't happen. This field is for validation purposes and should be left unchanged. QC = during, QA = after. Furthermore, it would do you an even better turn to realize that what you need is a process, not a plan. When the focus is on patient risk, the best strategy should minimize the chance that erroneous patient results are reported due to an out-of-control condition in a biased measurement procedure. – W. Edward Deming. As someone involved with your organization’s GIS and the users of that GIS, you have the chance to significantly influence the overall quality of each users’ experience. When it comes to software, the consumer of today has no time to spare for slow performing, defective or bug riddled applications. I’d like to suggest that they are quite different and each very important in their own right. I have a real concern about this since I feel that QA should be a stand alone department because we drive "quality" for all aspect of and for the company, not just one specific area. To know in detail, you have this video as a help At testbytes, we offer testing services such as, QA refers to Quality Assurance which is more of process oriented whereas QC refers to Quality Control and it is product oreinted. Your email address will not be published. Using a tool to immediately compare the shape length and measured length of a newly added conductor or main, and report back when those lengths differ by more than a specified percentage. This method is more reactive in nature as it identifies defects post the final production of the product. QC checks are conducted at different points in the development cycle to ensure that the final product meets and performs according to the agreed specifications.
