Don't sweat it, because this is exactly what we're here to explore.

Together, we'll take a guided tour through the world of both formal and informal mentorship strategies.

We'll break down the components, weigh up the pros and cons, and shine a light on those nagging questions, all to help you make a sound, educated decision.

So grab your favourite beverage, get comfy, and let's dive in!

The Mentoring Goldmine: Why it Matters

Think of mentorship as the fertilizer to your talent garden. It nourishes, supports, and promotes the growth of the individuals within your organization. How, you ask? It all comes down to the magical exchange of knowledge and experience from those who've been around the block (your mentors) to those eager beavers ready to learn (the mentees).

  • Guidance: Mentors are like the Sherpas of the professional world. They've climbed the mountain, weathered the storms, and can guide their mentees past the tricky obstacles towards their career summit.

  • Support: Mentors provide a comforting safety net, offering a boost of confidence when mentees are questioning their skills or feeling unsure or overwhelmed.

  • Knowledge Transfer: This one's a biggie. Mentors pass down the keys to success, sharing industry insights, shortcuts, and valuable life lessons they've picked up along their journey.

Formal Vs Informal Mentorship

Choosing between formal and informal mentorship is a bit like deciding between a carefully planned dinner party or a spontaneous potluck with friends. Both have their charms, but your choice will hinge on several factors such as your organizational culture, resources, and specific objectives.

  • Formal Mentorship: This is your meticulously organized dinner party. It's structured, with clear goals, predefined roles, and a set timeline. It often comes with a heaping helping of accountability, but some might find it a tad stiff.

  • Informal Mentorship: Here's your spontaneous potluck. It's flexible, and organic. The relationships tend to form naturally and evolve over time. It's a fun ride, but it can be a bit unpredictable and lacks the clear-cut goals of a formal program.

Now, before you feel overwhelmed, remember that our mission here is to get you all the info and insights you need to make a well-informed decision. So sit tight, as we'll delve deeper into these strategies in the coming sections.

Understanding Formal Mentorship

Formal mentorship, as the name suggests, isn't a casual or informal setup. Instead, it's a well-structured and planned mentoring program implemented within organizations. This style of mentorship involves matching mentors to mentees based on certain criteria and objectives. The relationships established in this context have a crystal-clear purpose and a formalized structure (meaning a beginning and end of relationship commitment and likely program milestones).

Think of it like a symphony where each mentor and mentee are musicians playing their part, guided by a well-structured music sheet. Just as the symphony has a conductor directing all the players, a formal mentorship program has clearly defined expectations and roles.

Here's a bit more about what you can expect from such a setup:

  • The mentor-mentee pairing is conducted based on guidelines that support your organization’s objectives for creating a program to begin with.

  • The mentoring relationships are established with distinct expectations and a formalized arrangement.

  • Periodic reviews are carried out to ensure progress towards goals and help mentors/mentees make necessary amendments.

Ex: General Electric (GE) and Intel's Formal Mentorship Programs

Now, let's consider a couple of real-world examples for a better understanding. Two notable corporations that have adopted formal mentorship programs are General Electric (GE) and Intel.

  • GE's program primarily focuses on developing leadership skills and endows mentors with the necessary training and guidelines. Just as a seasoned gardener trains a young sapling to grow straight and strong, GE's mentors guide their mentees in their leadership journey.

  • Intel's program on the other hand, emphasizes career growth. It offers a structured framework for mentorship, ensuring that every interaction adds value to the mentee's overall career aspirations.

By having these structured programs, both GE and Intel ensure that mentorship within their organization is not left to chance but is a well-oiled machine working towards the growth of their employees.

Advantages and Challenges of Formal Mentorship

Just like any other system, formal mentorship comes with its unique set of advantages and challenges.


  • Clear structure and defined goals can enhance accountability and ensure progress. It's like having a roadmap for a journey, helping you to stay on track and reach your destination.

  • Access to experienced mentors who can provide specific guidance in areas of their expertise. They act as personal navigators in a mentee’s career journey.

  • Opportunities for mentees to build diverse professional networks (outside of their department) within the organization. It's akin to being in a vibrant community where everyone is eager to learn and grow together.


  • Limited flexibility and potential for rigidness in the mentorship process. It's like walking on a set path. While it ensures you don't get lost, it can at times feel like it is limiting exploration.

  • Formal programs require some amount of administrative support, akin to the need for a well-maintained vehicle for a smooth journey.

  • Matching mentors and mentees solely based on predetermined criteria may not always result in the best fit, just like forcing a square peg into a round hole.

Although the challenges of formal mentorship programs might seem daunting, remember, no mountain is too high to climb. With clarity of purpose and a bit of set-up time – or help from a mentorship partner, these challenges can be turned into stepping stones for a successful and scalable program.

Exploring Informal Mentorship

If formal mentorship is like a structured symphony, then think of informal mentorship as a spontaneous jam session. But don't let its spontaneity fool you; it can be just as harmonious and enriching in its own unique way. In this section, we'll take a deep dive into what informal mentorship is all about, and why you should care about it.

Definition and Characteristics of Informal Mentorship

Informal mentorship is like that friendship which just clicked from the get-go. It’s not born out of a planned

program or formal introductions but emerges naturally due to shared interests, experiences, or a mutual respect between two people.

Here's what makes it special:

  • It's spontaneous: Informal mentorship blossoms without a premeditated plan or structure. It's like finding a rare gem in the rough of daily interactions.

  • It's all about the bond: The relationships here are authentic, rooted in organic connections and mutual trust. They don’t hinge on formal guidelines but on interpersonal chemistry.

  • It's free for participants to shape as they wish.

Ex: Google's "g2g" Program and Facebook's Culture of Informal Mentorship

Now, you might be asking, "That sounds great, but does it work in the real world?" Well, ask Google or Facebook. These tech giants aren't just pioneers in innovation; they're also champions of informal mentorship.

  • Google’s "g2g" (Googler-to-Googler) program: It's a simple idea, really. Encourage Googlers to connect with each other, learn from each other, mentor each other. No rigid structures or processes. The result? A thriving culture of knowledge-sharing and continuous growth.

  • Facebook’s informal mentorship culture: Facebook takes a similar approach. They encourage employees to learn from each other, fostering a culture of continuous improvement and innovation.

Benefits and Challenges of Informal Mentorship

Like a coin with two sides, informal mentorship comes with its own set of benefits and challenges. Let's take a peek at them:


  • Flexibility and adaptability: Informal mentorship adjusts to participants’ needs like a well-tailored suit. It allows for tailored advice and guidance that fits the individual's unique requirements.

  • Authentic relationships: The bond in an informal mentorship is like a self-watering plant. It grows naturally, fostering trust and open communication.

  • Culture of learning: Informal mentorship weaves a culture of continuous learning into the fabric of an organization. Learning opportunities can arise at any moment, making the whole journey exciting and enriching.


  • Lack of structure: Informal mentorship is like a compass without a set destination. The lack of defined goals may lead to less accountability and direction which can be frustrating or de-motivating for participants.

  • Depends on initiative: It’s like a garden that needs consistent care. Informal mentorship flourishes when individuals take the initiative and are properly prepared or trained ahead of time, but that may not always happen consistently.

  • Scaling concerns: Informal mentorship is a boutique hotel, not a chain. It’s personalized and charming, but can be difficult to scale to accommodate larger organizations (particularly when you consider wanting to provide equal access to participate in programs like mentorship).

  • Bias beware: With informal relationships it is easy for like-minded people to connect and while this has its benefits it also can limit accessibility and unintentionally isolate other employees and create conditions for “group-think” and confirmation bias. There is a lot to be learned when employees can connect outside of their department, field, culture, gender, etc.

Choosing the Right Type of Mentorship for Your Organization

You might be asking yourself, "What kind of mentorship is right for my organization? What are the factors I should consider?" Well, let's dive right into it!

1. Factors to Consider in Making the Decision

Here are the major things you should keep in mind when deciding the kind of mentorship to implement:

  • Organizational Culture & Employee Needs: Is your organization the kind of place that’s all about process and structures, or do you thrive more on loose connections and informal chat?

  • Resources Available: Have a good, hard look at what you’ve got to play with. What existing resources do you have to support mentorship? Do you have a budget; if so how much? Do you have someone or a team of people who will support mentorship programming? How much of their time can you allocate to this? What systems or software do you have or will you purchase to support mentorship? How will you support your mentors/mentees? (i.e. Can you host onboarding, provide mentor and mentee training, create reference materials/support guides or mentorship toolkits).

  • Objectives of the Mentorship Program: Are you clear on “why” mentorship or what problem you’re looking to use mentorship to help solve? Get clear on what you want this mentorship program to achieve. Do you want to focus on skill development, improving retention, enhancing company culture, leadership development, employee engagement or all of the above?

  • Feedback from Employees: Don't forget to listen to your team! Do you know how your employees learn best? What are your employees seeking or asking for? Gather their thoughts and feelings about mentorship.

2. Importance of Experimentation and Hybrid Approaches

You don't need to feel locked into one or the other - formal or informal mentorship. There's a whole world in between that allows you to combine elements of both. In fact that’s what we see most often. It's all about experimenting and finding the right balance that works best for your organization. A hybrid approach could provide the structure (and clarity for employees participating) of a formal program while still allowing for mentors/mentees to choose how often and how they connect, adopting more of the flexibility that can come with an informal setting.

3. Quick Reference Guide for Choosing Between Formal and Informal Mentorship

And just to make things easier for you, here's a quick guide to the key characteristics of both formal and informal mentorship:

Formal Mentorship

  • Time-bound,

  • Specific objectives and ideal learning and career development outcomes

  • Objectives-driven matches

  • Regularly scheduled meetings and program milestones

  • May take more time for mentors/mentees to build rapport

  • Can be more resource-intensive (but typically only for the first time)

Informal Mentorship

  • Natural, organic matches

  • Up to participants to decide if they want to set goals or objectives for relationship

  • Meetings as needed or desired

  • Can be as short or long as participants decide

  • Strong personal connections

  • Less resource-intensive, but may lack adequate support for mentors and mentees

So, take a minute to reflect.

Review the pros and cons. Consider your organizational culture, employees, resources, and objectives. Ask your team what they think. And remember, you can mix and match to create the perfect mentorship program for your organization.

It's all about finding the balance that works for your organization. Monitor results and if you’re not seeing what you’d like, make adjustments until you get it just right.
