Address the issue by initiating open communication with the vendor to understand the root causes of their underperformance. Set clear expectations and establish measurable performance benchmarks. Implement regular progress reviews and provide support or resources if needed. Consider renegotiating terms or penalties for non-compliance to hold them accountable. If performance doesn’t improve, explore alternative vendors or backup solutions to minimize project disruption. Maintaining collaboration and transparency will help resolve the issue and keep your project on track.

first need to understand which area communication is fail or not in order, start with beginning of the instance and divided into multiple instance, pick those instances where risk can mitigate and look those area where vender's performance is not optimal and start working with proper set of interval to enhance the vender's performance

In the past, I’ve had similar situations where a vendor has jeopardize, smooth function, and performance many times I have found that it starts at the top and there’s a lapse in communication somewhere along the line if clear performance expectations are set but are not getting communicated in an efficient manner. A reapproach may be necessary with who you’re communicating with and what extent. If a problem continues despite best efforts a change in vendors or a reassignment in who fulfilling your orders can help.

I've previously implemented review and expectations plans for vendors, and they've bounced back, delivering better than ever. On the flip side, I've also conducted risk assessments, opting to replace vendors with better options based on their responsiveness or performance. I believe the step-by-step comments mentioned below effectively address the main actions needed in an efficient and fair manner. Our end goal remains the same: maintaining high standards and clear expectations and ensuring that our partnerships are both productive and mutually beneficial.
