This week you will be discussing issues that can arise from gathering job analysis information from differing SME's (subject matter experts). As you know, job incumbents, supervisors, and other SME's (e.g., customers) often give different information about the tasks and KSAOs required for a job.

• Explain why you think this happens.
• 
  
• Do you think disagreement between supervisors and incumbents represents a lack of reliability and/or validity? What implications does this have for doing a good job analysis?
• 
  
• Should job analysts collect their information from just one source or across all sources? Why?
• 
  
• How can this issue be addressed?
