Your team member keeps missing deadlines. How will you ensure project success despite their tardiness?

Completely concur with your sentiments. It's a matter of EQ, which the majority of leaders lack, or cannot comprehend what it is!

There are often many reasons impacting missed deadlines that lie outside the realm of work. Approaching the person with sensitivity and tact to establish what the problem is will go a long way in helping them meet future deadlines and fostering a trusting environment where they can approach you first the minute they anticipate running into challenges with meeting deadlines. Be quick to listen and slow to penalise, until you fully understand what the challenges are

"Realistic" is the key word here. For example, if they have struggled with writing-heavy tasks, give them fewer of those, or allow for a later deadline when they are assigned those. If they only work part time, don't assign them 40 hrs/wk worth of work.

When a team member consistently misses deadlines, project success hinges on proactive and strategic intervention. One seldom implemented yet highly effective strategy is the "Shadowing System." This involves pairing the tardy team member with a high-performing peer who demonstrates exemplary time management skills. Through daily or weekly check-ins, the high-performer provides guidance, accountability, and insights into efficient workflow practices. This system not only fosters peer learning and motivation but also creates a supportive environment where deadlines are respected and met. By embedding mentorship into the project timeline, you transform a potential bottleneck into a catalyst for team growth and project excellence.

Assuming: 1) We have the right person for the job skill wise 2) Goals are clearly defined and communicated to the team 3) Team is fully enabled and they have easy access to all resources and information needed for execution Potential Solutions: 1) You may want to talk to them to understand if they have any personal issues or any concerns at work that are causing any distress 2) You can gauge for intent issues and address them as best possible This would be a WIP and may not immediately solve the problem. Keep a contingency plan ready and pass on some of their work to a trusted resource who may have some free bandwidth, till you see some improvement in the performance of your first team member.
