In my work we mostly use surveys and sometimes observations. We send surveys out to all users of our systems to get feedback on how our system is working and recommendations/suggestions to improve the systems. Surveys must use careful wording in the questions to prevent confusion or bias. This method is very quick and efficient; however it is sometimes difficult to gain in-depth knowledge from a survey and there is no guarantee that the person taking the survey is being open and honest. Before a new system goes live we do a user acceptance testing and part of that participants are carefully observed in their natural setting without interference by our team Adams, Khan, Raeside and White (2007).
For Walmart, environmental sustainability has become an essential ingredient to doing business responsibly and successfully. As the world’s largest retailer, their actions have the potential to save their customers money and help ensure a better world for generations to come.

Apart from serving as an incentive program, it also assist the course of hiring and retaining workforce that in turn aid the company achieves its goal by serving its customers and remaining competitive in the retail industry Researchomatic (2012).
Researchers use many different methods for conducting research. Each method has advantages and disadvantages that make it suitable for certain situations and unsuitable for others. Bias is the distortion of results by a variable. Common types of bias include sampling bias, subject bias, and experimenter bias. Sampling bias occurs when the sample studied in an experiment does not correctly represent the population the researcher wants to draw conclusions about. Research subject’s expectations can affect and change the subject’s behavior, resulting in subject bias. Experimenter bias occurs when researchers’ preferences or expectations influence the outcome of their research. In these cases, researchers see what they want to see rather than what is actually there. A method called the double-blind procedure can help experimenters prevent this bias from occurring. In a double-blind procedure, neither the experimenter nor the subject knows which subjects come from the experimental group and which come from the control group Sparknotes (n.d.).
