Draft Feedback on Areas for Improvement (Manager)

Help me draft constructive feedback for an employee, '[Employee Name]', on areas for improvement. 
Area 1: '[e.g., Attention to detail in reports]'. Specific Example: '[e.g., The Q2 report contained several data inaccuracies that required rework.]'. Desired Change: '[e.g., Implement a double-checking process before submission.]'
Area 2: '[e.g., Proactive communication on project roadblocks]'. Specific Example: '[e.g., A delay on Project Y wasn't flagged early, impacting the timeline.]'. Desired Change: '[e.g., Provide weekly updates on potential risks or delays.]'
Draft feedback that is specific, behavior-focused, explains the impact, and suggests actionable steps for improvement. Ensure a supportive tone.
