To answer this question, you need to understand the activities involved in the selection and implementation of a testing tool. Let's go through each option to understand why it is correct or incorrect:
Option A) i, ii, iii - This option is incorrect because it includes activity iii, which suggests implementing the selected tool on a project behind schedule to save time. This is not a recommended practice as it can introduce additional risks and potentially worsen the situation.
Option B) ii, iii, iv - This option is incorrect because it does not include activity i, which is to investigate the organization's test process. Understanding the organization's test process is crucial in selecting and implementing a testing tool that aligns with the organization's needs and requirements.
Option C) i, iii, iv - This option is incorrect because it does not include activity ii, which is to conduct a proof of concept. Conducting a proof of concept helps evaluate the tool's capabilities and suitability before making a final decision.
Option D) i, ii, iv - This option is correct because it includes all the recommended activities during the selection and implementation of a testing tool.
The correct answer is D. This option is correct because it includes investigating the organization's test process (i), conducting a proof of concept (ii), and identifying coaching and mentoring requirements (iv), which are all important steps in ensuring the successful selection and implementation of a testing tool.
