Talent Onboarding Guide #4

You've won the engagement. The SOW is signed. Your first day is approaching. Now comes the real test: can you deliver the transformation you promised?

The first 90 days of a fractional engagement are make-or-break. Get them right, and you'll build a strategic partnership that could last years and generate significant referrals. Get them wrong, and you'll struggle to renew, damage your reputation, and potentially lose a valuable reference.

The pressure is intense. You're working part-time but expected to deliver full-time impact. You're an outsider who needs to quickly become a trusted insider. You have limited time to understand complex business dynamics while simultaneously driving meaningful change.

Most experienced executives underestimate this challenge. They assume their expertise will automatically translate into fractional success. But fractional leadership requires a different skill set: rapid relationship building, accelerated context acquisition, and the ability to drive change without traditional authority structures.

The fractional leadership paradox

You need to go fast and slow simultaneously

Go fast on: Demonstrating value, building credibility, delivering quick wins

Go slow on: Understanding context, building relationships, making major changes

You need to be confident but humble

Confident about: Your expertise, methodology, and ability to solve problems

Humble about: Company culture, internal dynamics, and existing relationships

You need to lead without authority

Unlike full-time executives, you can't rely on organisational hierarchy. Your influence comes from expertise, results, and relationships – not job titles.

Relationship building strategies

Understand the power dynamics

Formal authority: Who officially makes decisions? Informal influence: Who actually influences decisions? Coalition building: Who are your natural allies? Potential resistance: Who might be skeptical of change?

Build trust through competence and character

Competence signals:

  • Asking insightful questions that reveal expertise
  • Providing valuable input in meetings
  • Delivering on commitments consistently
  • Solving problems others can't

Character signals:

  • Giving credit to team members for successes
  • Taking responsibility when things don't go as planned
  • Showing genuine interest in their success
  • Maintaining confidentiality appropriately

Adapt your communication style

For analytical types: Lead with data and logical reasoning For relationship-focused types: Emphasize collaboration and people impact For results-oriented types: Focus on outcomes and efficiency For creative types: Emphasize innovation and possibilities

Common first 90-day mistakes

Moving too fast on major changes

The mistake: Trying to implement everything at once without building foundation support.

Why it fails: Creates resistance, overwhelms the team, and increases failure risk.

Better approach: Sequence changes logically, building on early wins to create momentum.

Not investing enough in relationships

The mistake: Focusing entirely on deliverables while neglecting stakeholder relationships.

Why it fails: Even great work can fail without internal support and adoption.

Better approach: Invest 40% of your time in relationship building during the first month.

Being too prescriptive

The mistake: Telling people exactly what to do without involving them in solution design.

Why it fails: Creates dependency and resistance rather than capability and ownership.

Better approach: Involve team members in designing solutions they'll need to implement.

Ignoring company culture

The mistake: Implementing solutions that work elsewhere without adapting to local culture.

Why it fails: Culture eats strategy for breakfast, especially for part-time leaders.

Better approach: Adapt your approach to work within existing cultural norms.

Not measuring and communicating progress

The mistake: Assuming good work speaks for itself.

Why it fails: Stakeholders may not recognize value without clear communication.

Better approach: Establish metrics early and communicate progress regularly.

Proving ROI and building renewal case

Track leading and lagging indicators

Leading indicators (show early progress):

  • Process improvements implemented
  • Team capability development
  • System adoption rates
  • Stakeholder satisfaction scores

Lagging indicators (show business impact):

  • Revenue or cost metrics
  • Efficiency improvements
  • Customer satisfaction changes
  • Team performance improvements

Document everything

Progress tracking:

  • Weekly accomplishment summaries
  • Before/after comparisons
  • Stakeholder feedback collection
  • Metric improvements over time

Story development:

  • Specific examples of problems solved
  • Quantified business impact
  • Team member development stories
  • Process improvement case studies

Communicate value proactively

Monthly reports should include:

  • Progress against SOW objectives
  • Key accomplishments and wins
  • Metrics improvements
  • Challenges addressed
  • Plan for next month

Stakeholder feedback:

  • Regular check-ins with key stakeholders
  • Formal feedback collection at 30 and 60 days
  • Documentation of positive feedback
  • Address concerns proactively

Setting up renewal conversations

Start renewal discussions at day 60

Why early: Gives time to address concerns and adjust approach if needed

How to initiate: "I'd like to start thinking about what success looks like beyond our initial 90 days. Based on results so far, what would you want to see in an extended engagement?"

Position ongoing value

Focus on: What problems will arise if you leave vs. what opportunities exist if you stay

Example framing: "We've solved the immediate challenges around [original problem]. The next phase would focus on [emerging opportunities] that could deliver [potential value]."

Offer multiple engagement options

Scaled engagement: Increased scope or time commitment Specialized focus: Narrow focus on specific high-value initiatives Transition planning: Help hire and onboard full-time replacement Advisory relationship: Ongoing strategic guidance at reduced commitment

Red flags that indicate problems

Lack of engagement from key stakeholders

Warning signs: Cancelled meetings, minimal responses, avoided conversations

Likely causes: Unclear value proposition, poor relationship building, competing priorities

Actions: Direct conversation about expectations and value, increased relationship investment

Slow adoption of new processes

Warning signs: Team members reverting to old ways, resistance to change

Likely causes: Insufficient involvement in design, inadequate training, cultural misfit

Actions: Increase involvement in solution design, additional training, cultural adaptation

No measurable improvement by day 45

Warning signs: Metrics flat or declining, no visible progress

Likely causes: Wrong problem diagnosis, poor implementation, unrealistic expectations

Actions: Reassess approach, adjust strategy, reset expectations with stakeholders

Exclusion from strategic discussions

Warning signs: Not invited to important meetings, last to know about decisions

Likely causes: Haven't established strategic credibility, focusing too much on tactics

Actions: Demonstrate strategic thinking, request inclusion in planning discussions
