1The last video left the partnership unable to respond with one voice. This one is about why it succeeded anyway, and then about a harder question the chapter puts to its own case study.

2Despite those challenges, PARTNERS succeeded. The approach was applied successfully in Estonia, Latvia, Lima, Manila, and Tomsk, with reported cure rates between sixty-one and eighty percent — remarkable for a disease once thought untreatable.

3In March 2005, the World Health Organization passed a resolution integrating this treatment into global policy. The Global Fund adopted requirements that all countries using its resources for multi-drug-resistant tuberculosis must receive Green Light Committee approval.

4So what made the difference? First, the goal was clear and compelling. When challenges arose, partners could refocus on what they were trying to achieve. Kim's vision — enabling patients to live productive lives in areas where the disease was endemic — kept people motivated.

5Second, roles were well-defined from the start. Even when collaboration frayed, each organization knew its responsibilities and delivered on them. Third, partners learned and adapted. Paul Zintl, who joined Partners in Health during the project, took lessons learned in Peru directly to his next challenge, treating HIV and AIDS in Lesotho. We went in there not knowing what we were going to find, he said, but knowing that much of what we had learned in Peru would be needed.

6And fourth, the First Mile investments paid dividends. Because they had established the Green Light Committee and clear organizational roles early on, the partnership could weather storms that might have sunk a less prepared collaboration.

7So what can you take from this into your own work? First, invest heavily in the First Mile. The time you spend establishing shared goals, clarifying roles, and building trust isn't wasted — it's the foundation that holds everything together when things get hard. As one adviser put it, a common problem of many failed programs is that they haven't resolved key components in the first mile. They have unrealistic expectations, no mutually agreed goals, no clear strategy, and too little trust.

8Second, include the people most affected. PARTNERS learned this lesson the hard way when Peru's health sector reform upended their plans. The Roll Back Malaria partnership had a similar experience when African ministers of health pushed back on recommendations that didn't account for their practical realities. As one minister told the partnership board: it is good to give us recommendations, but our problems are multiple. If you are not taking them into account, we will never implement this change in policy.

9At the end of the day, what holds collaborations together? Ian Smith, adviser to the World Health Organization's director-general, put it simply. The glue of a partnership is trust, yet a lot of partnerships are born out of mistrust. The challenge is to create that trust. And trust doesn't appear automatically. It's built through the work of the First Mile — clarifying goals, defining roles, establishing norms. It's reinforced through consistent communication and follow-through during the Journey. And it's tested when things go wrong, which they inevitably will.

10Global health partnerships face what one leader called powerful centrifugal forces — changes in governments, shifts in funding, turnover in membership, and competing organizational agendas. These forces constantly pull partnerships apart. Only trust, what Rosenberg describes as the foundational capital of collaboration, can hold them together.

11Before we close, I need to acknowledge something uncomfortable. This chapter opened with a call to decolonize global health — to question who holds power, who sets agendas, and whose knowledge counts. Then I walked you through a case study in which the catalytic convening, funding, and global policy leverage flowed primarily through institutions based in the Global North.

12PARTNERS changed policy and saved lives. That matters. But keep noticing who had the authority to define the problem, to scale the solution, and to declare success. Also notice something more subtle: whose reflections and interpretations are easiest to find in the published record. Peru's Ministry of Health enters this narrative most vividly when a sovereign restructuring disrupted the partnership's plans. It's a useful reminder that when a partnership's center of gravity sits elsewhere, national decisions can be narrated as external forces rather than as governance.

13I don't raise this to dismiss what PARTNERS achieved. The principles in this chapter — vision, trust, communication, defined roles — matter regardless of who leads. But applying those principles inside an inequitable structure doesn't make the structure equitable. So what would genuinely equitable collaboration look like? I don't have a complete answer, but I suspect it starts earlier than most partnerships do: communities and local institutions setting the agenda, funding flowing directly to local organizations, and success defined first by those most affected. That requires those of us with institutional power to give some of it up.

14Paul Farmer put it simply. With rare exceptions, all of your most important achievements on this planet will come from working with others — or, in a word, partnership. He wasn't being sentimental. He was stating a fact about how change happens. Remember that group project you dreaded? Global health research doesn't have to be like that, but it takes intention. This chapter asked you to hold two things at once: practical tools for making collaborations work, and critical awareness of who gets to lead them. That tension doesn't resolve neatly, and you'll need both. In the next chapter, we'll explore where research ideas come from.
