Definition and distinction

Peter Block Peter Block (born 1939) is an American author, consultant, and speaker in the areas of organization development Organization development (OD) is the study and implementation of practices, systems, and techniques that affect organizational chang ...
defines a consultant as "someone who has influence over an individual, group, or organization, but who has no direct authority to implement changes". He contrasts this with a ''surrogate manager'', who is a person who "acts on behalf of, or in place of, a manager". The key difference is that a consultant never makes decisions for the individual or group, whereas a surrogate manager does make decisions. Consultancy UK defines the role as providing "professional or expert advice in a particular field of science or business to either an organisation or individual".Consultancy.uk

within a specialized field". In his book, ''The Consulting Bible'', Alan Weiss defines that "When we onsultantswalk away from a client, the client's conditions should be better than it was before we arrived or we've failed." There is no legal protection given to the job title 'consultant'.

Subject-matter expert (SME) vs. consultant

According to ''Institute of Management Consultants USA,'' "The value of a consultant s compared to a Subject-matter expert (SME)is to be able to correctly diagnose and effectively transform an often ill-defined problem and apply information, resources and processes to create a workable and usable solution. Some experts are good consultants and vice versa, some are neither, few are both." Another differentiation perspective would be that a consultant sells advice, but an expert sells his expertise; or of Consultants vs. Coaches or SMEs vs. Team Leaders.

Contractor vs. Consultant

The consultant is in a role of sharing her or his knowledge and advice, whereas the contractor builds something for the client.

Consultants' view of a consultant

A study found that business consultants maintain a very humble approach in their partnership with the client and believe that the ultimate goal is to make the customer move forward. Further, consultants are conscious in amount of control and discretion which comes from the customer and understand that criticism of their role is part of the work and sometimes even justified.

Role of a consultant

The role of consultant outside the medical sphere (where the term is used specifically for a grade of doctor) can fall under one of two general categories: * Internal consultant: someone who is employed by and operates within a client-organization (maybe as part of an ''internal consultancy unit''); or * External consultant: someone who is employed externally to the client (either by a

or some other agency) whose expertise is provided as part of a contract for a fee or rate.

Business case for hiring a consultant

Traditionally, by hiring a consultant, clients have access to deeper levels of expertise than would be financially feasible for them to retain in-house on a long-term basis. Moreover, clients can control their expenditures on consulting services by only purchasing as much services from the outside consultant as desired. Additionally, consultants are key persons with specific domain-skills in creating strategies, (e.g. ), leadership coaching, interim management (also called ''consultant manager''), etc. Another business-case is that a consultant can save the company money: for example, a specialist tax-consultant who saves the company 20% on its taxes, and only charges 10% in fees, enables the company to net a 10% savings.

Delivery of service

Consultants provide their advice to their clients in a variety of forms. Reports and presentations are often used. Advice can be general (high degree of quality of communication) and also domain-focused. However, in some specialized fields, the consultant may develop customized software or other products for the client. Depending on the nature (also named mandate or

Employment status and career distinction

Consultants work for (consulting) firms or as freelance contractors. A consultant differs from a temporary worker insofar as she or he has, as detailed above, a highly specialized career and domain knowledge. This could be true for a temporary worker too, however, for example a medical consultant is unlikely to suddenly become a hotel receptionist, whereas a temporary worker might change domains and branches more frequently. Furthermore, a consultant usually signs a service-type employee contract (known as
fixed-termA fixed-term contract is a contractual relationship between an employee and an employer that lasts for a specified period. These contracts are usually regulated by countries' labor laws, to ensure that employers still fulfill basic labour rights rega ...
, full-time, part-time), whereas a temporary worker will only be offered a temporary (and scope limited) contract or a work-results type contract (e. g. in Germany a specific type of contract called ''Werksvertrag'') to fulfill or create a specific work. Additionally, a temporary worker might be directed and managed by a client, whereas a consultant is employed by a company (or self) and provides services for a client. The consultant may not be provided work-related instruments or tools, but only the necessary infrastructure and accesses the consultant needs to fulfill the statement of work, e. g. access to internal IT networks or client-side laboratory. Moreover, a consultant might engage in multi-project services ( matrix organization) for the client or for internal projects/activities at the employer firm. The consultant's career path is usually not at the client's side, however the consultant will very likely be introduced into the client's organizational program or project structure.

Consulting scope

A consultant's activity can last anywhere from an hourly consultation, to a one-day service, three months, 12 months or more. For complex projects, a longer period is needed for the consultant to analyze, resolve the root cause, get to know the stakeholders and organizational-situation, etc. Usually the engagement has set legal boundaries under given law to avoid (specifically for freelance-contractors) the problem of

). The person at client location is sometimes called a ''Resident''. By spending time at the client's organization, the consultant is able to observe work processes, interview workers, managers, executives, board members, or other individuals, and study how the organization operates to provide hers or his services. In some settings, a consultant is signing a specific contract and is hired as an interim manager or executive with advanced authority or shared responsibility or decision making of client-side activities, filling a vacant position which could and cannot be filled with an internal candidate. This is often the case by the client-organization due to other constraints, such as corporate compliance and HR-processes, which lead to prolonged hiring paths beyond six months, which is often inacceptable for leadership roles.

Hartel's 10 Golden Rules

According to management consultant Dirk Hartel, the following ten objectives or rules are key to a successful consulting career: # Customer first - Especially the meaning of being available (time) for customer needs # Appearance - Understanding of self-image and dress for the job # Determined friendliness - Having concrete mindset and goals, but being diplomatic too # Punctuality - Leading time management, starting and finishing on time, being prepared # Engagement and productivity - Supporting, being pro-active, etc. # Critical questioning - Nobody is born a consultant; asking the right questions is a key skill # Feedback - Request regular feedback, asking for critique rather than waiting for it # Acceptance of hierarchies - Professional navigation in client organization, knowing authority-levels, being respectful and being confidential with customer information # Stakeholder behavior - Study and understanding of client behavior and culture; inspiring stakeholders with presentations, etc. # Being courageous - Consulting-life is challenging, never lose trust in yourself, but also reflect and lead a positive and good life

Consulting challenges


Consultants are often outsiders to the client organization. On one hand, this means their work methods, expertise, behaviors, etc. differ from the client-employees and organizational, and is exactly what the client needs, however it can also be a considerable disadvantage for a successful engagement and may lead to a less intimate cooperation with the client's business.


Next to general challenges, domain-specific challenges for consultants exist. In
palliative medicine Palliative care (derived from the Latin root ''palliare, or'' "to cloak") is an interdisciplinary medical caregiving approach aimed at optimizing quality of life and mitigating suffering among people with serious, complex illness. Within the publ ...
consulting, emotions, beliefs, sensitive topics, difficulty communicating and prognosis interpretation, or patients expectations despite critical illness are some of the challenges faced by the consultant.

Ethical conflict (manipulation)

According to Kelman, "One danger is that he counselordoes not recognize the control that he is exercising over the client's behavior. The other is that he is so convinced that he is doing good for the client that he does not realize the client that he does not see the double-edged nature of the control he is exercising." A consultant therefore needs to be aware and in control of her or his manipulative influences in particular couseling settings.

Expectations (customer)

Hartel mentions several challenges that are based on the types of consultants, including a consultant in a short-term role, as integrator, as driver, as project manager or methodology guru, know-how expert, or as scapegoat. In case of ''consultant as integrator'', the consultant has the challenging task to resolve, negotiate, facilitate, mediate political situations in companies to move forward, such as different opinions, critical characters (persons), difficult relationships or interfaces, goal conflicts, power games, etc. In case of ''consultant as scapegoat'', the consultant, who is external to the company, is the one to announce difficult company decisions such as layoffs or reorganizations, but it is important that the consultant acts professional and competent, not just as "

in suit".


Consultants may face several organizational challenges, e. g. internal consultants are faced with the paradoxes to maintain a good balance between knowing the internal company structure and at the same time staying neutral and objective, keeping a marginal position between the client and the provided service. Further, depending on the hiring company's understanding how to work with a consultant, the consultant might be seen as disruption to the inhouse employees status.

Other general challenges

General issues faced by a consultant can be stress, productivity issues with meetings, general "technostresses", high-paced and changing business environments and situations, etc.

Stakeholder management

In case of corporate and industrial consultants, the role is further challenged to act and become the "translator of information" from various different client-company cultures and procedures (processes) and between her or his employer-side team, managers and leadership team. What is an important goal to the current client is usually not similar for any other client due to multiple variations in company size, history, product, program, organizational structure, leadership, etc. Hence the consultant must be excellent in sensing and communicating between different layers in the organization and further across it, while maintaining authenticity, integrity and trustworthiness with all parties involved.

Taxation and legal status

Independent consultants (contractors or freelancer) usually need to fulfil taxation requirements given by laws, specifically challenging employment status to avoid 'disguised' employment. Compared to contracting, consulting can be seen as being "in business in your own right", not controlled by your client, etc. placing a consultant "well outside" of e. g. IR35. Alan Weiss provides 20 "factors" for consultants in the US (IRS), which are similar in other countries, to avoid or understand in terms of their business activity. Amongst those, the consultant is not supposed to be instructed by the client, should not receive similar training as employees, has the right to sub-contract, should not be integrated into the organizational structure, etc. to avoid legal-status and taxation issues.
