A leadership advisory company helps an organization assess, develop and select its leaders. Typical services are leadership assessment (including 360-degree feedback and assessment centers), executive coaching, leadership development programs, succession planning, culture and team advisory, and often executive search. The firm advises; managers and the board still make the decisions.
Key Takeaways
- Leadership advisory combines the assessment, development and selection of leaders; large firms such as Korn Ferry, Spencer Stuart, Heidrick & Struggles, Russell Reynolds Associates and Egon Zehnder pair it with executive search.
- Gallup reports that managers account for at least 70% of the variance in employee engagement across business units, which is why companies invest in who leads their teams.
- Classroom training alone rarely changes behavior; development programs that run over roughly 6 to 12 months and mix feedback, coaching and on-the-job goals are more likely to stick.
- Choose a firm on relevant experience, its assessment methods, the credentials of its coaches and how it will measure results.
Ineffective leadership is one of the main reasons for business stagnation and even failure. This is why so many businesses are turning towards the services of a leadership consultant. But, what will a leadership advisory firm actually do for your business?
Leadership Advisory and Development
Leadership consulting involves evaluating the current management and supervisory strategies to see what areas are performing well and where there is room for improvement.
The consultant looks at each level and function of the business, and at how they relate to one another, to understand how decisions are actually made and carried out.
They will also assess the existing leadership or management styles, as leadership development is a critical part of this service, which involves developing inherent leadership qualities, not only among managers but for employees in general.
This can involve a wide range of approaches, from changing the current business culture to training sessions that are designed to aid the process of developing leaders.
A consultant may also advise that some existing management positions are redundant, or suggest creating new leadership roles where responsibilities are unclear.
No matter what approaches are suggested, this service has the purpose of helping an organization to become more efficient by using the talents and skills of the people that are available to them.
A leadership consultant will also look for gaps in the current skill set, for example leaders who have not yet managed larger teams, budgets or change programs, and recommend how to close them through training, coaching, hiring or new assignments.
Many degrees can now be earned online, even an MSW degree, and so it is really easier than ever before for people to get more qualifications and enhance their skills. A consultant will be able to look at your business and see whether or not there is room for improvement in certain areas and they will help you go about this in the correct way.
Of course, this is only going to be the case if you choose a leadership advisory company with care. There are so many different factors that you need to consider. Needless to say, experience is important, but it is all about relevant experience too.
After all, you need someone who has worked with companies of a similar size and nature to yours before. They should also have experience in your industry.
Checking this record will give you peace of mind that they are the right choice for you. You should also read feedback that has been left by people that have used the services of the company in question before.
Hopefully, you now have a better understanding of what you can expect if you hire a leadership advisory company. This is something that more and more companies are doing today because they want to move their business forward, and who wouldn’t?
What Is a Leadership Advisory Company?
A leadership advisory company is a consulting firm that specializes in the people who run an organization: how leaders are assessed, developed, selected and organized. It sits between general management consulting, which covers strategy, operations and processes, and executive search, which recruits senior people from outside.
Like other management consultants, a leadership advisor works from outside the organization. Unlike an interim manager, the consultant does not become part of the company; the advice supports internal management rather than replacing it.
Many of the best-known leadership advisory firms grew out of executive search, also called headhunting. Executive search firms are paid by organizations to identify and approach candidates for senior roles such as CEO, vice-president and non-executive director. Several of these firms now also sell leadership assessment and development as advisory services.
What Services Does a Leadership Advisory Firm Offer?
Most leadership advisory firms offer some or all of the services below. The table summarizes what each one involves and when an organization typically uses it.
| Service | What it involves | Typical use |
|---|---|---|
| Leadership assessment | Interviews, psychometric tests, 360-degree feedback and assessment-center exercises that measure a leader against the role | Before a promotion, a hire or a restructuring |
| Executive coaching | One-to-one sessions with a coach focused on specific goals and behaviors | New executives, leaders with a clear development need |
| Leadership development programs | Structured programs combining workshops, coaching, mentoring and stretch assignments over several months | Building a pipeline of future managers |
| Succession planning | Identifying critical roles and preparing internal candidates to fill them | CEO and senior-team continuity, family business handovers |
| Team and culture advisory | Diagnosing how the top team works together and aligning leadership behavior with strategy | Mergers, turnarounds, rapid growth |
| Executive search | Finding and approaching external candidates for senior positions | When no internal successor is ready |
How does leadership assessment work?
Leadership assessment uses several sources of evidence rather than one interview. Two common methods are 360-degree feedback and the assessment center.
360-degree feedback (also called multi-rater feedback) gathers ratings from a leader’s supervisors, peers, direct reports and sometimes customers, alongside a self-evaluation. Studies cited on Wikipedia suggest more than one-third of U.S. companies use some form of multi-source feedback, including 90% of Fortune 500 firms. Organizations use it mostly for development; using it for pay or promotion decisions is more controversial because ratings can be biased or manipulated.
Assessment centers evaluate candidates through job-related simulations, group exercises, presentations, interviews and psychological tests. The method was adapted for business in the 1950s at AT&T, where a study directed by Douglas W. Bray followed young managers for more than 20 years and found the method could predict organizational achievement. Data from 2020 cited on Wikipedia found that 34% of employers use assessment centers when recruiting managers, professionals and graduates. Firms often add psychometric testing for hiring to these exercises.
What does executive coaching involve?
Executive coaching is one-to-one development in which a coach helps a leader reach specific professional goals. Coaching differs from mentoring by focusing on defined tasks or objectives rather than general development.
Coaching is not a licensed profession, so credentials matter. The International Coaching Federation (ICF), a non-profit founded in 1995, awards three individual credentials. According to the ICF, as of September 2026 they require:
- Associate Certified Coach (ACC): 60+ hours of education and 100+ hours of coaching experience.
- Professional Certified Coach (PCC): 125+ hours of education and 500+ hours of coaching experience.
- Master Certified Coach (MCC): 200+ hours of education and 2,500+ hours of coaching experience, and a PCC credential first.

Why do leadership development programs last months, not days?
Leadership development programs run over months because one-off training rarely changes behavior. A 2015 study in the Proceedings of the National Academy of Sciences, as summarized on Wikipedia, estimated that as little as 15% of learning from traditional classroom-style training results in sustained behavioral change at work.
Development is more likely when a program combines several experiences over a set period, for example 6 to 12 months, such as 360-degree feedback, classroom programs, executive coaching, mentoring and reflective journaling, and when it sets goals after an assessment and checks progress against them. Baldwin and Ford link the success of leadership development to three variables: the learner’s own characteristics, the quality of the program and support for behavioral change from the learner’s supervisor. The wider case for this investment is covered in the role of employee training in organizational growth.
What is succession planning?
Succession planning is the process of identifying critical roles and the skills they require, then developing internal candidates who can step into those roles when they become vacant. Organizations do it themselves or with the support of specialist management consulting firms.
Smaller firms are often unprepared. A 2006 Canadian Federation of Independent Business survey found that only 10% of independent business owners had a formal, written succession plan, 38% had an informal, unwritten plan and 52% had no succession plan at all.
Why Do Companies Hire Leadership Advisors?
Companies hire leadership advisors because the quality of managers has a measurable effect on the rest of the workforce. According to Gallup, managers account for at least 70% of the variance in employee engagement scores across business units, and companies fail to choose the candidate with the right talent for the job 82% of the time.
Gallup’s State of the Global Workplace 2026 report, covering 2025 data, put global employee engagement at 20%, its lowest level since 2020. Engagement among managers fell from 31% in 2022 to 22%, and Gallup estimates that low engagement cost approximately $10 trillion in lost productivity in 2025.
Common reasons to bring in an advisor include a CEO or senior-team transition, a merger, rapid growth that outpaces existing managers, poor engagement survey results and the need for an independent view of internal candidates. Approaches such as inclusive leadership and transformational leadership often feature in the development work that follows.
Who Are the Major Leadership Advisory Firms?
The largest leadership advisory firms also run executive search businesses. As of September 2026:
| Firm | Founded | Headquarters | Ownership and scale |
|---|---|---|---|
| Korn Ferry | 1969 | Los Angeles, USA | Listed on the NYSE (KFY); fee revenue of $2.9 billion in the fiscal year ended April 30, 2026, across Consulting, Digital, Executive Search, Professional Search & Interim and Recruitment Process Outsourcing |
| Spencer Stuart | 1956 | Chicago, USA | Privately held; about $1 billion in annual revenue as of 2022, according to Wikipedia |
| Heidrick & Struggles | Not verified here | Chicago, USA | Privately held since December 10, 2025, when a take-private transaction backed by Advent International and Corvex Private Equity completed and its shares stopped trading on Nasdaq |
| Russell Reynolds Associates | 1969 | New York, USA | Provides leadership advisory and executive recruiting services |
| Egon Zehnder | 1964 | Not verified here | Described on Wikipedia as the world’s largest privately held executive search firm |
Many smaller boutiques and independent consultants offer similar services, often focused on one industry or region. Fees are not published in a standard way and vary by firm, service and scope, so ask for a written proposal before committing.
How to Choose a Leadership Advisory Company
Choose a leadership advisory company by testing its experience, methods and accountability before signing. These steps help:
- Define the problem first. Write down whether you need assessment, coaching, a development program, succession planning or search, and what success looks like.
- Check relevant experience. Ask for examples of work with organizations of a similar size, industry and situation.
- Ask how they assess leaders. Ask which tools they use (360-degree feedback, psychometric tests, simulations), how they validate them and who sees the results.
- Check coach credentials. Ask whether coaches hold an ICF credential (ACC, PCC or MCC) or an equivalent, and how many coaching hours they have.
- Agree on measures. Set measurable outcomes, such as engagement scores, retention of key people, promotion readiness or time to fill senior roles, and a review date.
- Clarify conflicts and confidentiality. If the firm also does executive search, ask whether it will later recruit your people for other clients, and how assessment data will be stored and shared.
- Speak to past clients. Ask for references and read independent feedback, not only case studies on the firm’s own website.
Common Mistakes When Hiring a Leadership Consultant
- Buying a one-off workshop and expecting lasting behavior change.
- Leaving out the participant’s manager. Supervisor support is one of the three variables Baldwin and Ford link to successful development.
- Using developmental 360-degree feedback for pay decisions without telling raters, which invites biased or manipulated ratings.
- Leaving succession planning until a vacancy appears, which forces a rushed external search.
- Agreeing no measures, which makes the return on the fee impossible to judge.

Frequently Asked Questions
What is the difference between leadership advisory and executive search?
Executive search finds and recruits external candidates for senior roles. Leadership advisory assesses, develops and organizes the leaders a company already has, and helps decide whether an external hire is needed at all. Many large firms offer both.
Is a leadership consultant the same as an executive coach?
No. A leadership consultant works at the level of the organization, such as structure, succession and culture, while an executive coach works one-to-one with an individual leader on specific goals. Some consultants also coach.
How long does a leadership development engagement take?
The length depends on the service. Development programs are often designed to run over a set period such as 6 to 12 months, so that feedback, coaching and practice have time to change behavior; a single assessment or search project is usually shorter.
Do small businesses need a leadership advisory company?
Not always, but small firms often lack a succession plan. A 2006 Canadian Federation of Independent Business survey found 52% of independent business owners had no succession plan at all, so a short advisory project on succession or management structure can be worthwhile.
What credentials should a leadership coach have?
Coaching is not a licensed profession. A common benchmark is an International Coaching Federation credential: ACC, PCC or MCC, which require from 60+ to 200+ hours of education and from 100+ to 2,500+ hours of coaching experience.
