How To Get the Most Out of External PartnersEvery business depends on external partners, consultants and agencies. But, unlike your own employees, you don't control their tools, systems and work product. Here's how the best leaders manage third-party contractors.

Whether for a few extra hands on deck for a particular project, a bit of advice on a critical decision or a need for specialized skills temporarily, most businesses will eventually reach a point where they need tocall in reinforcements.

But simply hiring a top-notch consultant, agency orfreelancerwon't guarantee top-notch results. Unfortunately, there are many ways for that relationship to turn sour or fail to meet expectations, even among parties that enter the agreement with the best intentions. To avoidcommon mishapsand get the most out of engagements with external partners, it's essential to:

1. Vet
2. Set clear expectations
3. Trust (but verify)
4. Align incentives
5. Document (or it didn't happen)

1. Vet

Before you can outsource work to anexternal partner, it's always worth exploring multiple options andfinding the one that is most alignedwith your needs. However, finding a partner with the necessary skills and resources to get the job done is just the first step. It's also worth exploring some of their past work when possible, especially those that share some common characteristics with the project you're considering them for.

It's also important to compare some of your key characteristics as a business against their past clients. For example, if you're an early-stage startup, you might find it challenging towork with an external partnerthat only has experience offering services to enterprise clients. Extra points can also be given to those with expertise in your industry or niche or who have worked on projects with similar characteristics.

Furthermore, while asking for references is worthwhile, you will likely get better intel from a past client they didn't hand-select. Instead, explore whether you have any mutual contacts or connections on social media platforms likeLinkedInor through industry groups. Look for other back-channel ways of getting an unbiased reference from former clients or colleagues.

2. Set clear expectations

No matter how friendly or casual the engagement, getting formal with yourexpectationsis always critical. Even an old college friend getting paid to look over your business plan for a few bucks on the side should clearly understand your expectations and vice-versa. That includes mutually agreed-upon pricing, timing, check-ins, deliverables and reviews. Most of all, however, it's important to align on expectations and reach a mutual agreement on how you'll measure success.

3. Trust (but verify)

Agreeing on a mutual definition of success and measurements of progress is key tobuilding trust, but so is checking in at regular intervals to verify those expectations are being met. Ideally, you'll want to verify and review their progress regularly enough to catch early warning signs that things might be going astray, thus leaving yourself enough time to change directions or terminate the partnership entirely before it progresses too far.

4. Align incentives

External partners' livelihoods aren't as closely tied to the business's success as internal stakeholders. The reality is that it's their job to generate as much revenue as they can for themselves, which is why giving them a financial stake in your success is always beneficial.

For example, an external recruiter that's paid a percentage of a new hire's salary will focus more on quantity and salary than quality and value. Rather than incentivizing them to hire someone, it's important to incentivize them to hire the right someone. For example, you might want to consider a bonus structure that pays out based on how long the employee stays on with the company or consider offering stock options so that they are directly invested in your business's success.

5. Document (or it didn't happen)

It's essential to recognize that external partners likely aren't just providing their services to you. They might deal with multiple clients daily, and the more projects they juggle, the easier it becomes for things to slip through the cracks. That is whydocumentationis essential in maintaining high-trust relationships with external partners. Everything you think is important to the success of the engagement — including goals, milestones, deadlines, evaluation process, expectations, critical decisions and even the incentive structure, should be committed to writing in a mutually accessible location. Doing so will help minimize miscommunications and misunderstandings and keep everyone on the same page.
