There are usually 2 timescales to consider. First, the timescale of the project or activity – in this case 3 months to find a new house and move there. Second, the time over which the benefits shall be realized. In this case it’s 5 years until the kids leave school.,

CostsInternational Diploma in Business Analysis

The costs of doing the project or activity is the next important bit of information. On this project, the costs of moving to a new house will be £5,000. These are the project costs. (IDBA)

However, the couple will spend an additional £2,000/year for every year over which the business case is calculated. For a project in an organisation, this is usually referred to as the operational costs of maintaining and operating the projects outputs e.g. an IT system. At this point, the couple knows the total costs over the timescales when the benefits shall be realized. from the

Business case example 2: Handheld device project.

Imagine a heating repair services company that uses a paper-based set of forms filled in by an engineer during site visits. The spare parts required to fix the heater are recorded on a form which is given to staff to process back in the office. They then order the parts, and schedule a follow-up visit for the engineer to fix the heater.These certifications help employers identify qualified candidates and support analysts in career progression, salary increases, and professional recognition.

Reasons (PCBAP)

The reasons for the project are clearly spelled out when describing the 3 current problems which the company faces.Intermediate

OptionsBCS

In this example, there are 2 options (other than do nothing) which have been examined. Each option is summarized and the reason why option 3 is the preferred option has been stated.Some experience recommended

Benefits40 multiple choice (1 hr)

The expected benefits of reduced overheads are clearly stated. Benefits should be measurable and quantifiable. That means that the benefits can be measured later. But what about the reduced errors, rescheduled appointments and customer contract cancellations? Aren’t they benefits?£250

Well, these are in fact something else – they’re called outcomes. Outcomes are the results of the changes which come about by using the new handheld devices. The ways you measure the improvements resulting from these outcomes are known as benefits.Recent graduates

Dis-benefitsPractitioner Certificate in Requirements Engineering

This example also contains a dis-benefit which is that the back-office staff morale will be lower due to reduced overtime payments. A dis-benefit, if you’re wondering, is a negative consequence of a project. It’s not the same as a risk which implies something uncertain. A dis-benefit is something which you know will happen because of the project and it has negative consequences for the organisation. It’s the opposite of a benefit! (PCRE)

TimescalesIntermediate

Just as we saw in the previous example, the business case contains 2 timescales – the project timescales (i.e. the time it will take to complete the project) and the benefits realization timescales (i.e. the time over which benefits are expected to be realized).BCS

CostsSome experience recommended

Again, there are 2 costs – project costs and the ongoing operational costs over the benefits realization timescale. When the decision is taken whether to invest in this project, the total costs (i.e. project costs and ongoing operational costs) are weighed against the expected benefits over the same time period.40 multiple choice (1 hr)

Risks£250

Investment appraisalPractitioner Certificate in Modelling Business Processes

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. (PCMBP)

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.Intermediate

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.BCS

SummaryInternational Diploma in Business Analysis

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

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.Intermediate

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.BCS

Whatever form your business case takes, remember one thing – it will help you or your organisation take sensible decisions about committing time and resources to a project or activity.Some experience recommended
