About

I am Sierra Willenburg, a project management pro with over 11 years of experience working on SaaS products, websites, and apps. I’m passionate about helping people build better products that support their business, and more importantly, their users.

I believe in a human-centered approach to just about everything – when we help our fellow creatures, we make a better world for all of us.

A few guiding ideas I follow:

  1. Put people first
  2. Change happens from the bottom up, so listen to those you work with
  3. Be generous with explaining what you do and why you do it
  4. Be transparent about what you can and will do with the information you get
  5. Follow up with people and show that you are working to make ideas realities

How I approach my work

Start by creating clarity

When problems are loosely defined, I work with stakeholders to clarify the problem, constraints, and what success actually looks like before jumping into execution.

I help teams and stakeholders set metrics, understand goals, and outline expectations. When everyone understands each others motivations, finding solutions that serve everyone’s needs becomes possible.

Focus on alignment and understanding

Different teams often want different things. My role is to surface tradeoffs, clarify ownership, and get people aligned enough to move forward — even when perfect agreement isn’t possible.

When people understand why they’re being asked to compromise, they’re more likely to contribute and collaborate.

Think big, plan practically

Shoot for the moon, and understand that space travel is a big undertaking. Don’t shy away from complex, game-changing projects but don’t go in to them without the support and planning needed to make them successful.

Facilitate communicate

I act as a central point of coordination, translating between teams and sharing information at the right time so decisions don’t stall. I help teams collaborate and find shared solutions. I ensure hand-offs between teams are smooth.

Make progress that matters

Teams become disengaged, executives get frustrated, everyone feels like they’re just a cog in the machine when the work they do isn’t tied to concrete outcomes and forward motion.

I keep projects focused on delivering real results, not just completing tasks or hitting arbitrary milestones.
