When Hideo first joined the marketing team at Purdy Coffee Roasters, he was an energetic member who inspired others with his enthusiasm and strong work ethic. As the marketing department grew in size, Hideo slowly slipped into the background of the group, putting less and less effort into his social media outreach work. The marketing manager, Charlene, noticed his absence at weekly meetings and asked other employees what was up. They revealed to Charlene that Hideo regularly failed to complete his work on time and that other team members had ended up picking up the slack to cover for him. Which of the following actions represents the most effective way for Charlene to address Hideo's poor performance within the group?

1. She should make it the group's responsibility to keep Hideo in line and assign the strongest performer in the group to watch over Hideo and keep track of how he spends his time.

2. She should offer incentives to the entire group for improving its performance in all areas of marketing, with rewards shared equally among members rather than basing them on individual performance.

3. She should physically separate Hideo from the group by changing the seating arrangements so that his desk is just outside her office, thus allowing her to watch over him closely and prevent him from slacking off.

4. She should assign Hideo to a smaller team with the three other online marketers in the department, and, since he is the social media expert, ask that he submit weekly reports charting his online activity on behalf of the brand
