How To Write a Business Case

What is a business case?Learn the fundamentals of ITIL service management.

A business case is the justification for some activity (e.g. a project) undertaken by your organisation. It weighs up the timescales, costs and risks of doing the activity against the benefits to be gained. Think of it as weighing up the pros and cons and then taking a sensible decision.Strategist DPI

A business case forms an essential component of the curriculum of the 3-day ITIL Strategist: Direct, Plan & Improve (DPI) course.best project management coursesSpecialist: DSV .3-day ITIL Specialist: Drive Stakeholder Value (DSV) course.

Personal business caseSpecialist: CDS

You may also use a business case to justify an investment you make in your personal life. For example, when you’re thinking of moving home to another area. You and your spouse will need to understand the costs of moving, the timescales and risks involved, and weigh these up against the benefits to be gained e.g. saving time traveling to your office, or your children able to go to a better school.3-day ITIL Specialist: Create, Deliver and Support (CDS) course.

Why have a business case?IT Learning Library (ITLL)™

Projects should not just start on a whim or because of vanity – although a lot of money has been wasted over the years on such BUSINESS LEARNING LIBRARY (BLL)™projectsAgile Learning Library (ALL)™.Business Analysis Learning Library (BALL)™

For business organisations, justification for a project usually takes a commercial form i.e. evaluating how much money could be made from the investment. For example, investing money in developing a new software app to bring first to market, might be deemed to bring certain monetary benefits (in terms of sales) which exceeds the costs of investment.

For government organisations, justification is probably not a commercial one, but could be based upon giving value for money to achieve certain benefits. For example, a public health campaign extolling the benefits of flu-vaccinations for elderly people, might be judged as giving greater value for money than having no campaign, and instead relying on treating patients in hospital once they have contracted the virus.Compliance Learning Library (CLL)™

With so many competing claims being made on scarce funds, organisations need the assurance that the decision they are taking is the right one. After all, there will not be enough funds to pay for all the ideas for projects which are floating around the organisation.IT Learning Library (ITLL)™

Who uses a business case?Business solutions

Business cases can be used by many different levels of management within an organisation. Not only are they used to justify the investment in an individual project, but also they are typically used by a _blankportfolio managementAbout office to help it decide which projects will contribute to the organisation’s strategic goals. That way, they can filter out the bad ideas for projects, and only fund projects which will contribute to strategic goals._blank

A business case is also often used by a project sponsor or project executive to help it decide if they should invest in a specific project.Blog

In all cases, the business case must be written and approved prior to any major commitment of resources.

What form does a business case take?EXPLORE SUBJECTS

Business cases can take many forms – digital or analogue. The tools you use to create one are also many and varied. Common business tools such as Microsoft Office might be used. Rather than being a document or slide deck however, it could equally be in the form of an email.Select your preferred subject.

Equally, a business case could be written by hand on a whiteboard or flipchart, or on the back of a cigarette packet!

What you should always remember is that a business case does not have to be a huge long document. In fact, it should be as short as possible, and only include the most important information. That way it cuts out the noise and provides decision-makers with just the right information to enable them to take sensible decisions.PROJECT MANAGEMENT QUALIFICATIONS & WORKSHOPS

Options considered

A business case should weigh up the competing options which have been considered. After all, there is usually more than one option.

The final section is the investment appraisal. The investment technique used in this example is called net benefits. As you can see from the table, the project and operational costs are recorded for each year of the investment.AGILE PROJECT MANAGEMENT COURSES

The project lasts 1 year which is why the project costs are zero after year 1. Of course, the benefits won’t be realized until the solution is in place and the company starts to use the handheld devices.Select your preferred training course below:

The net benefits are simply the total benefits minus the total costs. This shows that the company will start to get a return on its investment sometime towards the end of year 2. This knowledge is vital if the decision-makers are to take a sensible decision about whether to invest in the project.

SummarySelect your preferred training course below:

A business case is the most important document on any project. That’s because it justifies the investment.

It helps an organisation be clear about why a project is needed, and what the results of the investment will be. This is crucial because no organisation has unlimited funds to spend on an unlimited number of projects. Therefore, a business case gives confidence to senior managers when deciding to invest in one project rather than another.LEAN SIX SIGMA COURSES

However, as you have seen in this article, a business case is something which you can find useful when taking major decisions in your own personal life. Remember – a business case doesn’t need to be a lengthy document. It could easily be a few notes scribbled on the back of something or even sent in an email.Select your preferred training course below:

Who approves a business case?

Usually on a project, the project sponsor (the person or people who are committing the funds) will approve a business case. Before approving it, they need to have confidence that the problems have been addressed and the right solution has been selected, that the benefits are achievable and realistic, when the investment will pay off, and how big will the return on investment be.ITIL COURSES
