What disruptive actions have you done in your team to make them more productive? Basically, to raise the bar in their performance?

In my experience, managers often focus on the wrong things when trying to raise the performance level of their teams. I have found the best place to start is to focus on team strengths. Human nature is such to focus on the weaknesses of a team instead of the teams’ strengths. To help a team up their game, emphasizing the overall team strengths can install confidence for the team to take risks. Without risk taking, it is difficult for a team to get to the next level of performance.

Risk taking encourages team members to stretch and take on more responsibility over and above what the team already does. The key is to get a team comfortable to get out of their comfort zone, which can then encourage team members to take on challenges and expand their core competencies.

But perhaps the most important way to raise the level of the performance of a team is to create an atmosphere where it’s ok to fail. Even talented teams can fail. Teams need psychological safety to have a growth mindset to support increasing their performance level. If an environment of psychological safety exists, the team will feel safe for reasonable interpersonal risk-taking. The bottom line is the only way to raise the performance level of a team is to stretch the team by encouraging measured risk taking. No risk, no gain!

I wanted to say "brought them back to office" but that would be partially correct. Some of the steps we have taken in the recent past to get the performance up.

1. Permanent hybrid working; team lead decides the need and frequency for coming to workplace
2. Institutionalized daily and weekly reporting standards across teams
3. Performance linked incentives - cash, kind, ESOPs, time off etc.
4. Recognition to high performers in monthly townhall meetings
5. Open access to management for any query, issue, opportunity, whatever

I would guess that overall the culture of the organization has been redefined. There is a change in performance for the better. Attrition is also now under control !

Set clear expectations about project outcomes, activities and day to day to day tasks. 
Define education roadmap i.e. skills development plan and career progression plan. 

I would not call the actions take as disruptive. But the team has been pushed hard and in different directions pushing the boundaries of some comfort zones

Part 5 - for me this is a given but calling it out- best of breed collaboration, coordination and communication tools.
