Operational researcher
Operational researchers use their scientific and mathematical skills to help organisations solve problems and develop better systems and operational procedures
You'll examine an organisation's operations to find more effective ways of working, using a range of analytical approaches such as mathematical modelling and problem-structuring techniques. The organisation is then able to use this information to develop their strategic policy and make better decisions.
Operational research (OR) is used throughout industry, commerce, the public sector and government services to find solutions to a range of complex operational problems, such as how to:
- increase efficiency
- allocate finite resources effectively
- improve customer service
- improve processes and procedures
- increase revenue and profitability
- reduce costs
- manage and reduce risk.
Operational research is also sometimes referred to as management science. Job titles vary and may include operational analyst, operational research analyst or operations consultant. Check job adverts to make sure the job reflects the work of an operational researcher.
You'll need strong mathematical ability, good communication skills and the confidence to analyse large sets of data to succeed as an operational researcher.
Responsibilities
As an operational researcher, you will typically need to:
- interview managers and staff to define the operational problem and the results they would like to achieve
- gather relevant hard and soft data from systems and staff within the organisation
- collect and analyse data and develop models, often using spreadsheets, databases and pragmatic, numerical approaches to solve problems
- use analytical methods, such as simulation, network analysis, decision analysis, multi-criteria analysis, scenario analysis, soft-systems modelling, optimisation, game theory and queuing theory
- use mathematical programming techniques, including linear programming, and statistical methods and test hypotheses
- identify innovative and pragmatic solutions to clients' management problems and set up and test these solutions
- make recommendations to inform the decision-making process to agreed timescales and quality standards
- compile a report of findings and make presentations to clients, often requiring clear and persuasive explanation of complex processes to a non-technical audience, in order to help them make decisions
- outline the strengths and limitations of the analysis you've carried out
- develop and implement ways of quality assuring your work and analyses
- keep up to date with changes to operational research techniques and identify new opportunities
- (with experience) manage projects, staff and budgets.
Salary
- Starting salaries are typically between £25,000 and £30,000, depending on your qualifications and experience. Graduates on training programmes may earn more. For example, graduates on the Civil Service Government Operational Research Service Fast Stream programme start on a salary of £31,186. This can rise to £50,000 to £60,000 after completing the scheme and with promotion.
- At senior level, salaries can range from around £40,000 to £80,000. In the public sector salaries are likely to be at the lower end of this scale.
- Salaries tend to be higher in self-employment and consultancy where specialists are involved more in strategic planning. Salaries in this area may reach £100,000 or higher.
Salaries vary depending on your skills and experience, qualifications, location and the sector you work in.
Benefits may include a pension, medical insurance, life insurance and bonus scheme.
Income figures are intended as a guide only.
Working hours
You'll usually work 37 hours a week, although longer hours and weekend work may be required to meet project deadlines. Part-time work is possible.
There may be opportunities for hybrid working.
What to expect
- Work is mostly office based, unless you're working in consulting or for professional services firms when you will visit client sites. You'll have frequent contact with people at all levels of a business or service.
- Self-employment or freelance work is possible once you've gained experience. Opportunities are mainly found within consultancies.
- The majority of jobs are city based. There are more financial opportunities in London.
- The work is results oriented and customer focused with projects managed to strict deadlines.
- Overseas travel may be required in some sectors. Travel is more common in consultancies.
Qualifications
Most operational researchers are graduates, usually with a 2:1 or above. Employers typically look for graduates with a science, technology, engineering or maths (STEM) degree that has maths, statistics, management or computer science content.
Relevant subjects may include:
- data science
- economics
- industrial engineering
- life and medical science
- management science
- mathematics
- operational research
- physics
- statistics
- technology.
Although numerical degrees are the most common entry subjects, you can get into OR from a non-numerical degree or after working in another profession if you have the right combination of skills, experience and aptitudes.
You can also become an operational researcher through completing a Level 7 Operational Support Specialist apprenticeship (equivalent to Masters level), which combines paid work with part-time study.
Some large employers offer graduate training schemes where you may be able to specialise in operational research and analytics. For example, the Civil Service offers a Government Operational Research Service (GORS) Fast Stream scheme.
Some employers expect you to have an MSc in OR prior to entry, while others may fund new recruits to undertake a Masters part time. Search for postgraduate courses in operational research.
It's also possible to do a Level 7 Operational research specialist apprenticeship (equivalent to a Masters degree), which combines paid work with part-time study.
You may be able to secure funding for Masters courses via the Economic and Social Research Council (ESRC) or the Engineering and Physical Sciences Research Council (EPSRC). Some universities also have their own scholarships. Details of potential funding sources for research are listed by The Operational Research (OR) Society.
The OR Society holds a Careers Open Day, usually in November, which is attended by companies actively recruiting and universities running MSc courses.

Employers
One of the attractions of OR work is its variety. It contributes to the success of organisations across a range of sectors and business environments.
The following are some of the main areas where OR techniques are employed:
- Government Operational Research Service (GORS) - employs analysts across a range of departments involved in determining and executing government strategies, from forecasting demand for services, to minimising risks and modelling the impact of proposed legislation.
- Defence - includes computer modelling of attack and defence scenarios to help the armed forces plan in active service, as well as disaster relief. The Defence Science & Technology Laboratory (Dstl) runs a graduate development programme for scientific and technical graduates, including operational researchers.
- Events management - OR is used in areas such as designing venues, planning large events and managing audiences and spectators.
- Financial services - OR is very active within the major banks and other financial institutions.
- Health services - ORs are employed in the NHS for tasks such as determining how long patients will stay in hospital in order to work out how many beds, wards and doctors are needed. Their role includes reducing patient waiting times, increasing efficiency and reducing costs.
- Management consultancies - international business consulting organisations increasingly have sections that specialise in business modelling, statistics and OR.
- Manufacturing industry - ORs play a significant role in helping companies improve efficiency, reduce costs and make the most effective use of capital investment.
- Marketing - ORs help companies target marketing activities through data mining, as well as using modelling to forecast demand.
- Oil - OR techniques are used to increase performance and profit.
- Retail - the analysis of market and consumer information is a major and rapidly growing role for OR in the retail sector. OR techniques contribute to improving service and reducing costs.
- Sport - ORs are involved in the design of stadiums and Olympic villages, for example, and ensuring that they are safe for spectators to enter, exit and move around in. F1 is another area of sport that uses ORs to maximise efficiency and safety.
- Transport and travel - ORs are widely used by airlines, for example, to decide which planes to buy, where to fly to, how many seats to sell and what fare prices to offer. The profitable development of low-cost airlines has depended largely on OR.
- Universities and research institutions - ORs teach on a variety of university courses such as undergraduate and postgraduate management degrees and diplomas, as well as the more specialist OR and mathematics degrees.
Look for job vacancies at:
- Civil Service Jobs
- Government Operational Research Service (GORS)

Professional development
Many employers offer in-house training and short courses and may also support you to take a Masters degree if you don't already have one. New entrants are usually assigned to an OR team and work on projects under supervision, gradually taking on more responsibility as they progress.
OR is constantly changing, so you must keep your skills and knowledge up to date throughout your career. A range of training courses, seminars and conferences, including major international events, are organised by The OR Society. These courses offer a structure for continuing professional development (CPD).
With experience, you can apply for professional certification. The OR Society offers members three pathways:
- OR Society accreditation
- Chartered Scientist and Registered Scientist - offered by the Science Council
- Data Science Professional and Advanced Data Science Professional - offered by the Alliance for Data Science Professionals.
Each route has its own application criteria, and you can apply to the route(s) most relevant to you.
You'll usually need a PhD in OR for careers in universities and business schools, particularly those with a strong research emphasis. Being qualified at PhD level is also valued for senior management positions in both the public and private sectors. Search for PhDs in operational research.
Career prospects
Promotion and long-term prospects in OR are good for those with the right combination of skills and experience. If you stay in OR you could move on to lead a project or team, still undertaking some analytical work yourself, as well as managing the work of other analysts. From there, the next step would be to manage an OR department.
It's possible to use OR skills outside a pure OR function, working in a production or marketing department, for example, or to specialise in a particular area of OR.
Alternatively, you could move into a career in general management. There is an increasing number of senior managers and directors who have a background in OR as it provides an excellent insight into the ways that businesses operate.
With experience, you could also consider working freelance or setting up your own consultancy business.
