ERP is an acronym for Enterprise Resource Planning.
This type of software incorporates data from all sub-directions of a company into one enterprise system. To name a few: inventory and order management, accounting and finance, raw materials, production capacity, HR, workforce scheduling, customer relationship management (CRM), human capital management, etc. The resources are also called 4M’s. That means Man, Machine, Method, and Materials. Departments use these data in real-time to streamline processes and automate common tasks.
The main quality of all ERP systems is a common database. Some ERP systems offer a certain degree of synchronized reporting and automation. These systems are the outcome of the lack of spreadsheet capabilities for the company.
There are different options for ERP implementation. It could be on-premises, cloud or a combined version – hybrid. Hybrid examples are a platform as a service or infrastructure as a service. Small and medium-sized business use cloud versions. Because today they are less expensive and easy to deploy. Some ERP systems even take advantage of such next-generation technologies like AI or IoT.
ERP testing key aspect is verifying how your ERP software functions during the implementation. It’s a QA process to ensure that the ERP system operates properly before a company deploys an ERP software. It includes planning, design, execution, reporting stages. And also lasts after the software goes live.
ERP systems testing efforts mostly concentrate on ‘core testing’ and ‘implementation testing’. Core testing aimed at testing functionalities that are not likely to change in terms of business logic and UI. In implementation testing, gunpoint is the components that are in the development process. The main focus in ERP testing is on the functionality and performance of the ERP under different types of load and scenarios. ERP testing at different stages of the implementation excludes trouble at the final stage. It reduces the number of bugs that could occur after implementation.
During customization, other potential bugs can emerge as well. Any changes to the code might cause problems or reduce user efficiency. Integration testing involves assessing business scenarios.
By running the ERP system in a test environment and dealing with bugs at that stage, businesses can save a system downtime.
Other testing efforts for ERP systems include data handling, security, adaptability, usability, installation testing. The process might be conducted manually or automated.
Every module of the system should be tested to ensure that it works correctly and gives a business expected results. Users have to take part in the testing process too. Their questions and feedback allow making proper changes.
The main stages of efficient ERP testing are:
- Defining testing goals. ERP Applications are not only context dependent but also domain specific. Based on end business objective testing goals should be set. They serve as a guide on the type of ERP testing, composition of a testing team, and proper tools for testing.
- Identifying test cases and conducting tests. Enterprises don’t use systems with basic implementations. The reasons are peculiar business requirements. So it is crucial to test thoroughly areas which are customized to assist functionality in production. After the initial tests, changes in the objective of application functionality will expand the set of test cases. Now you may add tests to constantly examine problem areas. Here we bare in mind one of the Principles Of Software Testing – Pesticide Paradox. The set of test cases needs to be regularly reviewed and revised. This and notification of the main business operations are important actions to save funds and time.
- Analyzing defects and creating test reports. It’s essential to analyze failings which occur during the tests and report all of them. Based on this the testing team prioritize defects, corrects them, retest and close. Thorough reports help the team to evaluate test results and reuse test scripts and cases in the future.
The ERP software, all connected processes and procedures must be tested thoroughly. And tested together in close to a production environment.
ERP system testing has a lot of risks. With databases and with the correct customization within them as well. Yet, all this is leveled by the right techniques of risk mitigation. And eventually, proper testing is an insignificant price to pay when the outcome is a system that ensures substantial functionality for years.
