Site Acceptance Testing Definition

A story can have one or many acceptance tests, whatever it takes to ensure the functionality works. Each acceptance test represents some expected result from the system. Customers are responsible for verifying the correctness of the acceptance tests and reviewing test scores to decide which failed tests are of highest priority. Acceptance tests are also used as regression tests prior to a production release.

A user story is not considered complete until it has passed its acceptance tests. This means that new acceptance tests must be created for each iteration or the development team will report zero progress. Most of the time testers not only check that the equipment meets the specification, but also that it is fully functional. A FAT usually includes a check of completeness, a verification against contractual requirements, a proof of functionality and a final inspection.

Why is Factory Acceptance Testing Required?

For example, let’s say that our analog input card will receive 4-20 mA input signals from transmitters installed in the field. To test the output, all you need to do is to activate the inputs using simulated signals and see if the contactor on the output will be energized. Don’t take the hot power into your hand and try to connect it to the circuit breaker. I have made this mistake a couple of times during my career but I was lucky I did not touch the hot wire. To let the electricity come into the panel, you need to connect the power to the topside of the circuit breaker.

The PLC digital inputs are connected to the upside of the terminals highlighted in our control panel example below. The other side of the terminals will be connected to the switches and sensors once we take the cabinet to the site. Contract testing ensures that the specifications of a product have been met by suppliers, vendors, or manufacturers who have signed on as contractors to the production process. If something does not live up to the obligations spelled out in the contract, it must be rectified or legal action can be pursued. For example, inputs from either the field or the workstation software may be simulated to start one or more pumps.

Acceptance tests in delivering Engineering projects change in line with technologies – Internet Acceptance Testing (IAT)

The cost for FAT testing is normally included in the equipment procurement cost. The cost of an EFAT, when needed, is normally negotiated between the vendor and the operator. Factory Acceptance Tests are performed at the site of manufacture https://globalcloudteam.com/ of a piece of equipment before it is shipped to the customer. It sounds obvious but what we’ve heard from many agencies or companies looking for a good UAT tool is that they have a hard time recreating issues, and therefore, can not fix it.

The following blog post outlines the key differences between FAT and SAT. The other way to check the wiring diagram for your card is the manual. For example, this is the wiring diagram for the analog input card that I have installed in my control panel. When performing a FAT for a control cabinet that includes a PLC, like the example we have here, one of the most important things to test is the PLC inputs and outputs. As the first step, you need to connect the power to your control cabinet and turn it on. This is where the power comes into the control panel for all of the devices.

What Is the Role of UAT in the QA Process?

The needed competence for involved test personnel is described during the planning. It is recommended that personnel with experience suitable for the intended process https://globalcloudteam.com/glossary/site-acceptance-testing/ application and safety instrumented system deals with the FAT planning. The product must be assembled, prepared, and connected to utilities for testing.

• Maveryx Test Automation Framework for functional testing, regression testing, GUI testing, data-driven and codeless testing of Desktop and Web applications.
• Use this checklist to fully assess machine performance during the FAT.
• The tests are normally executed during the final part of the design and engineering phase before the final installation at the plant.
• It includes all facilities, hardware, software, firmware, procedures and/or documentation intended for or used to perform the testing of software.
• Test scenarios can be broken down into logical «days», which are usually where the actor (player/customer/operator) or system changes.
• For each analog output we can simulate a signal in the input and then check if the analog output changes based on what we expect in the PLC logic.

FATs almost always save time and money over fixing issues in the field. The FAT is a customized testing procedure for different types of systems and the tests are executed before the final installation at the plant. When a piece of new equipment is manufactured, it has the potential for countless errors. With an increase in the machine’s complexity, the error potential also increases. It is, therefore, required to test the equipment to find out if the equipment is working as needed without errors. This test is known as the factory acceptance test which is popular by its acronym “FAT”.

For custom and modular systems, SAT can be much more complex, as you would need to verify that each component was built according to the specifications before accepting them from the vendor. Prior to installation, equipment should be confirmed to comply with the URS/functional specification at the vendor site, if applicable. However, GAMP tells us this type of testing is not needed for GAMP Category 3 or 4 systems unless they are brand new and extremely complex. Whether FAT is needed for Category 5 systems that are dependent on the system type, novelty, and complexity. By integrating software bill of materials creation into the software development lifecycle, IT and DevOps teams can build more … Job-specific requirements as referenced in the customer specifications.

Or cosmetic degradation, is acceptable, so long as equipment functionality is not impaired in any way. With these in place, the tests have to be run and the results recorded. After practicing IAT for around 2 years, we have even decided to include this into our internal System Development Lifecycle. Which means we discuss the possibility of IAT during our negotiation of the SoW and project development and delivery stages and whenever possible we replace FAT or SAT with IAT.

Acceptance Testing Definition, Types, and Examples

Matrix Technologies is one of the largest independent process design, industrial automation engineering, and manufacturing operations management companies in North America. To learn more about our manufacturing operations management capabilities and manufacturing process control solutions, contact Matt Fether, Department Manager. At Matrix Technologies we are committed to delivering exceptional engineering solutions. Providing the final acceptance from the client perspective does not indicate the end of the relationship. A common misconception with regards to the SAT is that it is executing the same steps that were performed at the Factory Acceptance Test.

This is to remove technical ambiguity from the FAT and prevent disputes over work that continues after FAT. Hands-on training for the equipment operation can be taken from the manufacturer who knows all the nitty-gritty of the equipment. Accessibility requirements for operation and maintenance are checked. If it can be shown that the functionality is not affected by the transport and installation. Additionally, we recommend that you document configurations as you create them in order to get an overview of how you are configuring your system. By documenting your configurations, you ensure that you have a record to check for changes later on if the system changes.

How to Conduct Factory Acceptance Testing?

A poor or rushed FAT can lead to missed non conformities, which can only then be corrected after the equipment is installed—which in turn can wreak havoc on a project schedule. Raw data is taken, recorded, and submitted to the customer to prove the functionality. Equipment complying with the project-related drawings and specifications is ensured.
