Spot or Remote Usability Testing in Singapore
Spot testing can be in contact with the user face to face, can observe and record all the site information. For the remote test, although the situation is a high degree of restoration, the information obtained through the camera and the microphone is limited, a lot of off-site information, including the user’s body language, will be missing. In addition, the spot test easier to control the field, you can ensure non-interference environment, smooth network, you can also promptly answer the user’s questions, to ensure that users can focus on the test itself, while the remote test in the control field is inadequate. Finally, on-site testing requires fewer tools, whether it’s making a test prototype or building a test environment.
However, spot testing also has its limitations. Due to time, space and cost constraints, the spot test method is only suitable for small, limited sample tests. For example, researchers in first-tier cities, spot testing may only be recruited local subjects, difficult to reach other users. Lack of user analysis in third- and fourth-tier cities, the result of the final study is likely to be biased. In this case, low-cost remote testing will be a good supplement. Determine the use of spot testing or remote testing, mainly depends on the following points:
User distribution
If the target users of the products cannot be locally recruited, such as products for overseas markets, or the users of the products are scattered in geographical areas, for example, products that cover cities in the 1234th line in the whole country, the respondents who are recruited locally are not representative, Then remote testing is necessary.
Sample size
Spot testing is suitable for small sample testing. Unmanaged remote testing may be a better solution when large sample sizes are needed.
When to start the test
Field test and remote test choice, but also consider the usability test in the process of product development which stage. Most of the company’s R&D process can be broadly classified as demand phase, design phase, development phase, test phase and release phase. We put the end of the design as a dividing line, the usability testing can be divided into early intervention and late intervention.
Early intervention
Usability testing at this stage, there is usually not enough time to prepare and test, the prototype of the test and the final product on the line there will be discrepancies. However, the benefit of early intervention is that the product is not yet finalized at this stage, the results of the test can be immediately fed back to the product and designer for agile iteration, and the cost of landing and driving test results is relatively low. In addition, part of the usability test record can also be shared or omitted by getting involved with the product designer.
Late intervention
After entering the development phase, you can get prototypes closer to the finished product for testing (such as inline code into the program), but also have ample time to test. However, at this stage, product demand will be more cautious, and the difficulty of landing the test results will also increase. Therefore, more evidence support is needed. In the context of Tencent, the test results obtained at this stage, if accepted, generally to the next version to be scheduled.
For formative testing, we recommend testing early in the project. At this time will be more use of field testing methods. Testing is generally done after the interaction is completed, with the testing process and the visual design phase in parallel. Prototyping tools can be used to quickly generate mobile test prototypes. Tests can also be done during the product requirements completion phase, in parallel with the interaction design, but the test prototypes at this point are cruder.
