Editor’s note: Fieldwire is proud to feature construction expert Jim Rogers on our blog. Jim has decades of experience in construction management and safety, and is an instructor for LinkedIn Learning — an online library of video courses taught by industry experts from across the globe.
- LinkedIn Learning is a great source for construction management education and content, and it’s included if you have a LinkedIn Premium account.
- Jim enjoyed learning about Fieldwire so much that he created an online course on how to use Fieldwire to manage construction drawings and processes, that’s free for everyone during the month of December.
He then created this blog post for our readers who are eager to learn more about QA/QC processes. “Quality Assurance” and “Quality Control” are often times mistakenly used as interchangeable terms when discussing the broad issue of quality in construction; however, these two terms actually describe very different activities.
Although both work towards the delivery of a final product that meets the project’s specifications and customer’s expectations, they arrive at the outcome in two very different ways. Quality Assurance (QA), refers to the implementation of proactive processes that aim to prevent defects. Quality Control (QC) simply refers to the process of inspecting the product to identify and correct defects.
As a tool, QC can be thought of as a corrective tool, typically carried out by a specific group of individuals on a job site; the inspectors and project engineers who walk and document items that need corrective action. QA is a management tool that can incorporate everyone on the team through planned and systematic activities that aim to prevent defects before they occur. I think we are good at QC in construction. We tend to find our problems early and get them fixed so the client is happy and satisfied with the project. The real problem in construction is not that we hand over defective projects, it’s that before handoff we find so much that needs to be fixed! This is the rework problem that we see cited so often in the media and in the numerous studies out there that identify rework as a big issue in construction, and a major contributor to our industry’s productivity problem,
If there is any doubt, there are many studies out there that back this statement. Many reports, including this PDF from XL Catlin, put the total cost of construction at about five percent of total construction costs. One widely cited study by the Navigant Construction Forum states: “Average rework on projects can cost between 7.25% and 10.89% of total construction cost (when both direct and indirect costs are included) and can cause an increase in the schedule (project delay) of approximately 9.8% of the planned project time.” Where the goal of QC is to find any defects so they can be corrected before owner handoff, the goal of QA is to prevent these defects in the first place.
Yes, we do QA in construction. We certainly do it in the supply chain at the materials level where quality assurance programs are in place to ensure that the materials and components we use in the course of building a project are free from defects. In general, though, we do not do as good a job focusing on QA as we do focusing on QC, and that’s partly because many people in the industry don’t understand the difference.
If the goal of QA is to prevent problems in the first place, then one of the major objectives of a construction quality assurance program is to eliminate the rework that is so prevalent in the industry. One of the major causes of rework in construction is workers in the field not having the information they need to do the job correctly the first time.
Plan changes, updates, clarifications, and submittals that occur throughout the building phase of a project create a constant challenge in terms of ensuring that the latest information gets in the hands of the people that need it in a timely manner. The conditions that we are presented with simply overtax our currently used processes. Anytime I discuss digital workflows, I point to the RFI process. The Request for Information, or RFI, process on most construction projects is the ongoing, often a daily routine of asking a question and getting an answer about something on the construction drawings.
It is an important process. So much so that we have a very formal method of asking these questions using an RFI Form that, for every question, captures who is asking, exactly when they asked, who reviewed it, and of course, the form that documents the official answer. It’s good stuff, it’s necessary, but it doesn’t work.
The time it takes from asking a question, even a basic one, to the time it takes to get an answer, is staggering. As that process unfolds, the only person that really knows about the pending question is the person that asked it. Even worse, when the question does finally get answered, the only person who really sees the answer in a timely fashion is, again, the person who asked it.
Yes, the general contractor will typically send copies of the answered RFI to all the trades on the job, but this is ineffective at best. After all, if I didn’t have the same question in the first place, then what interest is it to me and my work? And who has time to sort through all those Q&A’s as they come into the office to figure out what pertains to us? None of this even begins to address how this information actually makes it into the hands of the crew in the field that are actually doing the work.
So, things get built wrong, we rely on the QC process to find those things, and then we fix them. That’s why that process and those RFI forms are so important. Because now we have to go back and figure out who is paying for the rework, and we need the data captured on those forms, so blame can be properly placed.
- This process needs to go away! There is no reason for it anymore, other than it has become so ingrained into the way we build that it’s tough to let go.
- Digitizing this paper process is not much help either.
- Instead, we need to leverage the digital tools that we have available right now to create an entirely new digital workflow.
One that is simple and effective. One that looks something like this: Paper drawings in the field are completely replaced by digital drawings. Questions that arise are easily asked directly on the digital drawing that is being shared and viewed by everyone. The implications and potential benefits are staggering. Delivery of information is instant and automatic. Questions and answers live directly on the drawings; the set of instructions being referenced by everyone. Field crews may see answers to questions that their office counterparts didn’t even know to ask.
A tradesperson may see an answer to a question that is entirely different from the way they may have interpreted it. People stop asking the same question over and over because they can see the question has been asked. And in the field, they can see a pending question that may affect the way they are about to build before they build it wrong.
This is one simple example. There are many more. Adopting entirely new digital workflows with an eye towards quality assurance and elimination of rework is vital to our industry if we are going to improve construction’s much-discussed productivity problem.

What is the difference between QC and QA?
What are the differences between quality assurance and quality control? – Confusion over the two terms is common, and there’s even disagreement over which tasks fall under which category. In discussing the differences between quality assurance and quality control, remember that the latter is part of the former, which explains some of the overlap. Here are five key differences between QA and QC: Proactive vs. reactive, QA starts at the very outset of a project, injecting some much-needed guardrails that keep products in scope and make them testable. The goal of QA is to establish a framework to minimize bugs from the beginning, and it even influences how programmers do their work.
QA influences how quality will be incorporated and ensured in a product, while QC reacts to the developed product by identifying and either fixing or triaging remaining defects, When it occurs, As we established, QA occurs throughout the entire software development life cycle (SDLC). QA isn’t a stage in development; it’s a continuous effort to implement, enforce and ensure digital quality.
QC, however, can only take place when there is a developed product to test. QC can take place both before and after a product’s initial release. Process vs. product, One of the primary differentiators in QA vs. QC is where the focus of the work lies. QA primarily focuses on the processes and procedures that improve quality, including training, documentation, monitoring and audits.
- QC focuses on the product to find defects that remain after development.
- QC professionals find these issues in a variety of ways, including software testing and beta or canary testing.
- Prevent defects, identify defects,
- Solid development practices — and even quality-forward practices such as test-driven development — can lead to fewer defects making it through to the QC stage, and even fewer reaching customers.
QA intends to prevent some defects from ever occurring, through collaboration practices to align teams and methods such as code reviews. Through QC, testers identify and prioritize what defects remain. The emphases are different, but the end goal is the same.

What is QA QC job description?
What Do Quality Assurance (QA) / Quality Control (QC) Engineers Do? – Quality assurance (QA)/quality control (QC) engineers are responsible for ensuring the quality of products and services produced by their company. They oversee the manufacturing of products and they are involved in every stage of making a product-from development and manufacturing to packaging.
What are the 5 types of quality control?
Q5. What are the four steps of Quality Control? – The first step for quality control is to set your quality standards and decide which ones to focus on. Secondly, you must establish operational processes to deliver optimal quality and implement them. The third step is to review your results and identify gaps. Lastly, get feedback and make improvisations.
Which comes first QC or QA?
1. What comes first, QA or QC? Since QA is involved during the initial phase of the Software Development and QC is involved during the execution phase of Software Development, QA comes first.
Why is QA and QC important in construction?
Quality Assurance Specifies Standards, Quality Control Verifies Compliance To Standards – A successful QA program aims to ensure that the quality procedures implemented during the design phase of a construction project effectively meet the company-established standards for quality service, performance, and production. The core specs focus on:
Qualifications established for architects, designers, and engineers Markup rules pertaining to plans and drawings from preparation thru revision and into final approval AND the assurance that specified materials comply with company-established quality standards.
QC is the process that ensures that materials used on the project actually comply with properly signed drawings and plans. Secondly, QC ensures that task-specific personnel actually perform construction project processes according to the specified QA standards.
Is QA higher than QC?
While some quality assurance and quality control activities are interrelated, the two are defined differently. Typically, QA activities and responsibilities cover virtually all of the quality system in one fashion or another, while QC is a subset of the QA activities.
What is QC purpose?
Understanding Quality Control (QC) – Quality control involves testing units and determining if they are within the specifications for the final product. The purpose of the testing is to determine any needs for corrective actions in the manufacturing process. Good quality control helps companies meet consumer demands for better products.
What are the 6 types of quality control?
Key takeaways –
- Quality control (QC) is the process of fulfilling quality standards, checking the products’ conformance to them, and improving product quality as a consequence.
- On the other hand, quality assurance (QA) is tasked with creating the conditions for fulfilling the quality requirements. Quality control is therefore focused on the product while quality assurance is process-oriented.
- There are many different approaches to QC, with some of the more popular methodologies being statistical quality control (SQC), statistical process control (SPC), total quality management (TQM), Six Sigma, and Lean Six Sigma.
- Every approach, however, is based around the regular inspection of goods.
- Although there are many dedicated quality management software, these are often too expensive and complex for smaller businesses. Fortunately, some ERP/MRP systems offer the required functionality for quality monitoring.

Is QC an engineer?
Who are your colleagues as a quality control engineer? – Quality control engineers are part of a bigger team tasked with ensuring quality standards and making quality improvements in the production process. As a professional quality engineer, you’ll work with the company’s management, data scientists, IT teams, business development experts, quality control technicians, product designers, software developers, and project managers.
What are the 3 types of quality?
The levels of quality that the authors talk about are: Acceptable quality. Appropriate quality. Aspirational quality.
What are the 3 main objectives of quality control?
Simply put: quality control is key to success in manufacturing. From both the manufacturer and customer perspectives, production inconsistencies and poor quality can result in various negative outcomes such as slower time to market, tainted reputation, strained supplier-OEM relationship – and worst of all, customer loss or harm.
- Companies that manufacture products for OEMs simply cannot afford to cut corners when it comes to quality.
- OEMs need a trusted manufacturing partner with a reliable and dependable process that yields consistent results – unfortunately, not all manufacturers meet this standard.
- Quality control and quality assurance are areas where contract manufacturers, like RiverSide Integrated Solutions (RIS), stand out from the competition.
A manufacturer’s quality program is more than just meeting the requisite ISO requirements – it represents their proven way to ensure consistent, high-quality parts. Consistent quality is hard work and requires rigorous, on-going monitoring of every process from purchasing to manufacturing to distribution.
- But the effort and focus on quality is well worth the reward.
- The primary goal of a quality management system is to improve the quality of the production process and final products.
- In such a system, there are 3 main objectives of quality control: enhance product quality and reduce risks, gain production efficiencies, and garner customer loyalty.
These 3 objectives will be evident in any manufacturer with a robust and functional quality control program.1. Enhance Product Quality & Reduce Risks : the economic and reputational cost of product recalls or failures is often really high. Manufacturers with solid and established quality programs consistently meet the requisite product specifications, and are less likely to have quality incidents such as off-spec batches or product recalls – reducing the level of risk for the supplier and OEM.
Who is responsible for QC and QA?
Comparison chart –
Quality Assurance | Quality Control | |
---|---|---|
Definition | QA is a set of activities for ensuring quality in the processes by which products are developed. | QC is a set of activities for ensuring quality in products. The activities focus on identifying defects in the actual products produced. |
Focus on | QA aims to prevent defects with a focus on the process used to make the product. It is a proactive quality process. | QC aims to identify (and correct) defects in the finished product. Quality control, therefore, is a reactive process. |
Goal | The goal of QA is to improve development and test processes so that defects do not arise when the product is being developed. | The goal of QC is to identify defects after a product is developed and before it’s released. |
How | Establish a good quality management system and the assessment of its adequacy. Periodic conformance audits of the operations of the system. | Finding & eliminating sources of quality problems through tools & equipment so that customer’s requirements are continually met. |

Who is responsible for quality control in construction?
Who is responsible for quality control in construction? As with any industry, quality control plays a particularly important role in construction. It implies that things get done the right way, following the plans, permits, and specifications that have been established.
Quality control ensures that standards are followed and implemented in the construction site. The ultimate quality of the construction project is reviewed close to its conclusion. A punch list of items that need to be corrected is followed in order to ensure that the finished project meets the expectations set forth at the beginning of the project.
The importance of having a quality control procedure An effective quality control program starts with spelling out the specific standards that must be met. Once that is established, the scope of actions to be taken must be determined. It is also important to determine what corrective action will be taken when needed.
- To be successful, a quality control program must be continuous, immediately detecting areas of trouble or concern, in order to implement the necessary corrective measures.
- Are there barriers to the success of a quality control program? In construction, there certainly are.
- Mostly, the fact that each project is so unique, the locations so different, the volume of work fluctuates, the tends to be temporary, materials tend to be delayed or out of stock, different subcontractors have their own schedules, etc.
The job of a contractor in such a situation becomes extremely challenging due not only to these but to many other unexpected factors. Who is responsible for quality control in construction? The primary person responsible for quality control in a construction site is the project or site manager.
- It is their responsibility to provide guidance as to the expected quality and results.
- Under this manager, each supervisor must be responsible for the quality control of everything that is performed and accomplished in their section of work.
- This responsibility must include not only the quality of the work performed but the quality of the materials used.
Can technology be your friend in order to reach your quality control standards? You may feel that investing in a digital control process could be extremely overwhelming. However, you must know that once that is in place it becomes progressively easier to manage.
- Taking it one step at a time may provide the most optimal results.
- A good starting point may be to implement a centralized document and issue management system.
- This will ensure that everyone on the site is working with the most updated plans and drawings and that there will be no issues that go unnoticed.
Also, time to resolution will be improved. You may also want to implement collaborative inspections with your subcontractors and trades. This way, you will not need to rely on inspections from the site manager to become aware of any mistakes. Problems crop up and the quality control manager cannot be present always and everywhere.
- The best quality control program will include a high level of collaboration which will hold every team member responsible for their actions and results.
- Establish a successful construction team by starting with the most efficient and experienced,
- Ultimately, they will be responsible for the final outcome of your construction project, implementing quality control procedures and ensuring the optimal completion of the job to your satisfaction.

Is QA difficult to learn?
How do I know if a career in software QA is a good fit for me? – Most everyone knows that right now is a great time to join the tech community, but some don’t have the time to learn how to code. Software assurance QA testing is easy to learn and not code intensive.
You will have to learn some coding, but not to the same extent as a software or web developer. Software QA test training typically takes six to ten weeks, whereas web development training takes anywhere from 12-26 weeks. Being a software quality assurance analyst could be a great fit for you if you’re good at communicating and like to break things.
Some other skills you will have to learn include functional automation and scripting, basics of web technologies, agile methodologies, and more.
Which job is better QA or QC?
QA makes sure you are doing the right things. QC makes sure the results of what you’ve done are what you expected. QA Defines standards and methodologies to followed in order to meet the customer requirements. QC ensures that the standards are followed while working on the product.
Final Thoughts – Both Quality Assurance (QA) and Quality Control (QC) are terms many people use interchangeably. However, the difference between the two is significant. You can see the main differences between QA and QC are visualized in the “Quality Assurance VS Quality Control” infographic.
- Quality Assurance (QA) is a combination of activities throughout the manufacturing process that ensures the quality of the product.
- Consequently, Quality Control (QC) is a set of processes used to secure that the product meets the quality requirements.
- Although, both QA & QC use statistical tools that are explained in the book Quality Control with R (Cano et al.2015).
The main point of Quality Assurance (QA) is to prevent any defects before they occur. Therefore, Quality Assurance (QA) is a proactive activity by its nature. On the contrary, Quality Control (QC) aims to identify any possible issues and verify the quality of the output.
Is testing part of QA or QC?
Council Post: The Distinction Between Testing And Quality Assurance In The Software Industry Margarita Simonova, founder and CEO of, getty Although it is sometimes thought that quality assurance (QA) and software testing are the same, they are, in fact, different concepts.
- They differ in their objectives, features and methods.
- Testers and QA engineers are also unclear about their job descriptions due to the many misconceptions about the nature of testing.
- I’m going to take a closer look at each of the roles in order to clarify them.
- What is QA? QA is the means through which the desired level of quality in a product is achieved and maintained.
It is an element of quality management that focuses on the maintenance of product or service integrity and provides reassurance that all intended requirements will be met. This approach creates a means of regulating workflow to simplify error tracking throughout the software development process.
- QA has been regarded as a pillar of success in IT solutions because it addresses a number of management issues, for example, checklists, project analysis and development techniques and methods, just to name a few.
- To achieve the highest quality and to track the progress of a product and the work of every team member, it is imperative that the strategy be followed throughout the stages of product development.
Every product development process is affected by QA: the pre-design phase, development, testing and product release. Ideally, with the use of QA, there would be no problems because it can simplify things and modify processes to eliminate the majority of them.
- In practice, problems are significantly reduced.
- A QA mindset is worthy of having and being shared with team members.
- Software Testing Explained Software testing is a way of identifying possible defects and bugs in a software product and ensuring that the action code written by the developers enables it to perform as expected.
A variety of methods are used for testing the product, locating errors and checking whether errors have been fixed. Testing gives you the opportunity to check if the developed product matches the expected requirements in terms of function, compatibility, design, etc.
- Generally, it can be defined as a group of processes aimed at ensuring that the existing version of the product produces results most similar to those specified in the expected requirements.
- Among the greatest benefits of testing in IT projects is providing clear and understandable error reports.
- Doing this enables developers to easily understand what failed and how to fix it.
It is noteworthy that testing is only able to spot defects and weaknesses in an existing product or smaller portions of it. QA Versus Testing Software testing assists with finding and fixing already existing errors, while QA helps prevent them. Both these processes play an important role in achieving optimum quality; they complement each other.
- QA focuses on ensuring that stakeholders are satisfied with the design, while testing aims to detect bugs or bigger shortfalls.
- Testing’s focus is error detection and system control, with corrective actions and product orientation.
- Testing checks the application’s behavior while QA improves the overall project quality each day.
Now that we have analyzed these two concepts, they can be compared in terms of subject matter, definition, purpose, orientation and type of action. QA is in control of the testing process while it ensures that the software’s performance is effective under certain conditions.
Testing’s focus is evaluation, case studies and implementation. QA is short for quality assurance, and it is common knowledge that product quality cannot be “tested.” Therefore, quality assurance merely optimizes the process so that quality can be achieved. Manual tests and their respective reports are often used to assess the success of such quality measures.
QA is a management approach that takes into account all the policies, processes, standards, training, tools and so on that are necessary to ensure the achievement of a company’s quality objectives. A good QA strategy is well-integrated and proactive as well as reactive.
Testing is only a tiny part of this strategy. The Relationship Between QA And Testing When QA connects with testing, it is referred to as quality control (QC). This methodology aims at locating errors in an application’s operation by testing the software using various test levels and types. The more test types covered, the better your chances of discovering all defects.
Each of the test levels covers distinct usage—for example, integration tests of web services when compared with acceptance tests with real users. QC is primarily product-oriented. It uses users’ recommendations and requirements to validate the product.
With this in mind, QC engineers write appropriate tests to ensure product compliance with those demands. QC is intended to prove that the product works as expected by either breaking it or finding discrepancies between requirements and the product’s current working results. The amount of testing required to make this determination is endless and will continue until the person responsible for the quality plan chooses to stop.
Testing is a part of QC. It is the process through which a system is built to detect faults in a product so that they may be fixed. Testing is fundamental to QC because it helps demonstrate that the product works as expected. This approach requires frequent detection, and this is equally as important as maintaining quality throughout the development cycle.
- It is almost impossible to achieve software quality with only one person performing QC activities.
- QC is a collaborative process, one in which teams work together from inception and at every stage of software development, focusing on quality.
- Quality means everyone taking responsibility for their work from the second production begins to the second it ends.
What is key to your project’s success and why? No one is infallible. We all make mistakes no matter how meticulous we try to be. While some of those mistakes may be negligible, others may be costly or even dangerous. Therefore, it is imperative that you test software from the very beginning so that errors can be found and corrected.
Is Tester QA or QC?
Testing – Testing is a subset of QC. It is the process of executing a system in order to detect bugs in the product so that they get fixed. Testing is an integral part of QC as it helps demonstrate that the product runs the way it is expected and designed for.
To summarize, think of everything as an assembly line. QA can be thought of as the process to ensure the assembly line actually works, while QC is when the products coming off the assembly line are checked to verify they meet the required specifications. Ultimately, both QA and QC are required for ensuring a successful product.
When used together, they can help detect inefficient processes and identify bugs in the product. Moreover, QA and QC can help to develop and deliver a consistently high-quality product to your customers. Please check our ultimate guide for all the related QA questions: “”.
