Task-Relevant Maturity (TRM)
Intel’s legendary CEO Andy Grove introduced Task-Relevant Maturity (TRM) as a framework for adjusting oversight based on a person’s expertise in a specific task.
Delegation only works effectively when it aligns with TRM:
- Low TRM → Micromanagement (step-by-step guidance, frequent check-ins, detailed corrections).
- High TRM → Autonomy (independent decision-making, proactive problem-solving, minimal oversight).
Think of it like learning to drive—at first, you need constant supervision in an empty parking lot, but over time, you’re navigating highways on your own.
Your job isn’t just to offload tasks—it’s to recognize and develop TRM so your assistant can operate at a higher level.
How to develop TRM faster: The 70-20-10 model
TRM isn’t built overnight—and if you rely solely on trial and error, progress will be slow and inconsistent.
The 70-20-10 development model is a proven framework for accelerating TRM by balancing real work, coaching, and structured learning.
When planning your assistant's development, consider allocating their learning experiences across three key areas:
1.) 70% On-the-Job experience – The majority of your assistant’s growth comes from doing the work. Assign stretch projects that push them beyond their current capabilities.
- Example: If they usually prepare internal reports, have them create a first draft of a board presentation.
2.) 20% Coaching & feedback – Regular reviews, specific feedback, and check-ins are critical for reinforcing what they’re learning.
- Example: Reviewing their email drafts together so they understand tone, context, and decision-making nuances.
3.) 10% Formal training – Some skills require direct education beyond hands-on learning.
- Example: If your assistant needs to improve data analysis, enroll them in a data visualization course.
Using 70-20-10 as a structured approach, you can intentionally build TRM instead of waiting for it to develop slowly over time.
TRM in practice: What to expect from your assistant
TRM isn’t a single score—it varies by task. An assistant might have high TRM in calendar management but low TRM in industry-specific tasks like investor updates.
That’s why delegation needs to be dynamic—some responsibilities can be fully handed off, while others require training and gradual development.
Areas where assistants typically have high TRM
- Scheduling meetings and managing conflicts
- Setting up recurring appointments
- Blocking time for focused work or personal commitments
Inbox management
- Sorting and prioritizing emails
- Drafting responses for your review
- Managing follow-ups and reminders
Travel & booking
- Arranging flights and accommodations
- Making restaurant reservations
- Coordinating logistics for business trips
Areas that usually require more development
Depending on your specific needs and industry, there are areas where your assistant might need more support to build their TRM:
Industry-specific knowledge
- Example: If you're a VC, your assistant may need to learn the basics of venture investing before they can draft LP updates or screen pitch decks.
- How to build TRM:
- Walk them through a recent pitch deck and explain how you evaluate deals.
- Have them sit in on partner meetings to absorb the decision-making process.
Company-specific processes
- Example: They need to understand your internal reporting structures and team dynamics before effectively managing projects.
- How to build TRM:
- Have them listen in on all-hands meetings and explain key internal dynamics and insightful observations
- Show them how reporting structures work and who actually gets things done.
Specialized tasks (e.g., Social media, content creation)
- Example: They may need guidance on brand voice, content strategy, and audience engagement before taking over social media or newsletters.
- How to build TRM:
- Review past social posts together and walk them through your content calendar and scheduling tools.
- Have them observe a brainstorming session, then guide them through creating a first draft of a post, infographic, or blog.
Final thoughts
Building TRM isn’t a one-time effort—it’s an ongoing process. Your assistant won’t start with high TRM in every area, but with the right mix of on-the-job experience, structured coaching, and formal learning, they can develop the ability to operate at a higher level.
