The Business Case method will become clear to you through this article which also provides its historical background and recommends situations for its application. The training will teach you about essential system elements and methods to create accurate financial models and risk evaluation techniques. The business case functions as an active document which we will demonstrate how to update when circumstances evolve. The article contains a business case template which enables you to start working immediately. Enjoy reading!

What is a Business Case?

Every business aims at a good cost / benefit ratio. A Business Case (BuCa) can be very useful in determining this. Using this well-structured document, a good and clear cost and benefit analysis can be produced, with which a business consideration is made to either start a project or not.

Business Case: the extensive form

In a BuCa the costs are carefully balanced against the benefits. This project management tool can be used in a simple and in an extensive manner.

In the extensive form a Business Case will focus on the starting points of the project, the various decision criteria, external factors, expected return, added value and possible risks.

Furthermore, the financing of a project will also be considered carefully. The information received from the business case determines whether a project will be carried out or not.

When is a business case really necessary?

Small enhancement suggestions do not require a business case to proceed. The tool functions best when an organization needs to decide between multiple options which involve substantial investments or dangerous initiatives or substantial modifications that affect operational workflows and customer service and staff members.

A business case becomes essential when the stakes reach their highest point. The actual implementation phase needs to handle projects which need major financial resources and require multiple years to finish and which depend on external entities to succeed.

The following examples demonstrate system implementation: organizations implement ERP and CRM systems and they build new facilities or shut down existing ones and they start new production operations and they launch digital transformation initiatives. The management team and steering committee need to monitor all related expenses and advantages and potential dangers together with the different options which were assessed during the process.

A business case becomes essential for projects which need minimal investment when their strategic value to the organization is substantial. The proposal creates changes which affect market positions and customer service operations and employee work methods. The financial approval process requires answers about how this project will help our organization reach its strategic targets.

Organizations use threshold amounts together with basic rules for their operations. Small improvements with limited risk can be decided at the departmental level, based on a brief justification. A complete business case becomes essential when a specific amount goes beyond the limit or when scarce capacity is needed or when there are rising security threats. The process reveals all decisions which the project leader and client and financial department must make during their work.

Finally, the level of risk also plays a role. A business case becomes necessary for projects which have small budgets but require complete dependence on one supplier and new technology implementation and compliance with essential laws and regulations. The business case shows different possible outcomes and required control methods and specific times when project modification or termination becomes necessary.

Up-to-date

The BuCa operates as a dynamic document which undergoes ongoing modifications throughout its typical usage. Team members need to update information during the project while the BuCa requires corresponding modifications. The project stays valid through review processes because they help us implement new modifications to the project.

Each BuCa may have to deal with changes and revisions. The revision process will either modify the project or it will result in its complete termination.

Business Case Analysis

A BuCa typically contains four fundamental components which make up its structure. The downloadable template contains 4 additional sections. You can modify the template sections by including or excluding them based on your project requirements. The article explains the basic four elements which form this concept.

The business case needs to establish its strategic context as its first step. All situations require proof that change must occur through a strong argument. An economic analysis is then performed, to determine the return on investment. The process requires financial help tools to achieve its objective. The upcoming sections will explain the project definition text and the document will finish with its project organization section.

Multiple managers from different departments participate in handling the business case. The management approach establishes role assignments together with governance structures and other organizational elements.

Decision-making around a business case

The BuCa is evaluated and revised at so-called decision gates, as more accurate estimates and information sources become available.

An approved BuCa clearly shows how decisions of the board affect the return on the investment, and how the highest return can be achieved.

By merging these approaches, the BuCa simply becomes an overview of the recommended options with substantiation and evidence to support the decision.

When the presentation of the business case has been received successfully, this results in the formal start-up of a project, portfolio, or program. The sponsor owns the business case and the project.

What are elements of a good Business case?

In every good business case several components must be discussed. Follow the guidlines below to write your business case.

Benchmark

Explanation about the background and origin of the project and its current status. The BuCa will be given a project name.

Context

The company objectives and business opportunities are outlined, so that the expected results become clear.

Profit proposal

Apart from a profit calculation, it also important to incorporate the profit planning and an extensive cost and benefit analysis and to elucidate the possible (financial) risks.

Delivery

In addition to the profits, possible benefits are identified as well as the internal and external impact of the project.

Workload

An estimate will have to be made of the deployment of resources and the organization of staff availability.

Considerations

It is important to draw up a business case at the earliest possible stage. Initially, this need not always be a detailed document. However, it is wise to make some considerations in advance.

Cost-saving or profit generating?

Where to put the emphasis? Is it about generating a profit or about austerity measures? If it is about of austerity measures, it is often difficult to make an estimate in advance. In case of a profit targets, the activities are related to increasing turnover.

Operational or strategic?

It is important to know in advance whether the Business Case will be integrated as an important part of the business strategy or whether this will be more department focused and whether this will be fulfilled by a team.

Quality or quantity?

Is the Business Case about an increase in turnover (quantity) or is it more aimed at better work processes and an (internal) added value for the organization as a whole (quality)?

Lean business case

A common mistake is to treat the business case as an oracle that ensures results in the future. The business case should be seen as a theoretical and strategic hypothesis supported by evidence gained through research.

To ensure this, it is important that the case remains focused, useful, and practical. Below are some tips to write the business case in such a way that it is in accordance with Lean principles.

Keep the case strategic

Make sure that as many strategic elements as possible are included in the BuCa. Analyse current market and industry factors and adjust the project strategy accordingly.

Distinguish facts from hypotheses

Identify and rank risky assumptions. Then prioritise these assumptions and evaluate the risks associated with deploying those assumptions.

Facts are only facts when the result of a particular experiment is the same time and time again. Some facts can also cease to be true when environmental factors change. Keep this in mind.

Check and revise

Run the project through a series of iterations. A product and business model evolve as the path to the customer is narrowed. If nothing changes in the course of months, this may be a point of reference that the team is insufficiently concerned with the market and industry factors. Start small, and add depth as the project progresses.

How do I write a business case?

In most organizations the (financial) managers are involved in drawing up and writing a Busines Plan. Broadly speaking, there are three steps that can be taken in the process of creating a Business Case. Work through the step-by-step plan listed below, to start using business cases in your work environment.

Step 1: Determine the reason

Why is the Business Plan drawn up? What needs to be improved? What are the business objectives? By carrying out a SWOT Analysis or Strengths and Weaknesess Analysis, an understanding of the company’s strengths and weaknesses can be obtained as well as the external threats and challenges. This will determine the course of action in creating the plan.

Step 2: Conduct a cost-benefit analysis

By having a good understanding of the costs and benefits of the organization in advance, it will become clear what the business case could lead to.

Step 3: Make an investment decision

It is important to have an insight into the finances. It is important to have a good understanding of the financing arrangements. How is the company doing in financial terms and what return does the organization anticipate after the business case has been implemented? Apart from making use of internal leaders, the expertise of external agencies can be involved for the drawing up.

Business case example

Below, you will find a brief explanation of the four basic parts of a business case. You will also find an example of a business case in the form of a practical template. The business case consists of about eight sections. Depending on the project and its size, parts can be omitted or added.

1. Executive Summary of the business case

Depending on the length and depth of the business case, it is wise to include a high-level summary of the project.

The executive summary is the very first section of the business case, but is written last. It is a very important part of the Business Case.

The summary presents a brief overview of the entire business case through essential project details which explain all aspects of the project. The person who discovers the business case might only read the summary before deciding to read the complete report. So make sure you have a good quality document. First impressions can be very important, especially considering this is the only part many members of the management team will read.

2. Finances of the business case

The financial part of the business case is intended for people who have to decide on, or approve the budget. The financial part, plus the first half of the project definition, is very important to people like project sponsors.

When preparing the financial appraisal, advice is usually sought from professional experts on the content and presentation to the financial public.

Financial appraisal serves to identify all financial effects which the project will create while keeping the project within budget and forecasting its monetary returns. The business case requires investors and assessors to evaluate its return on investment data. Read about the different calculations in this article, or download the Business Case template.

In addition, there is the sensitivity analysis within the financial part. This analysis mainly relates to the risks surrounding the project, and looks for alternatives by analysing the impact of assumptions which are uncertain. In fact, the sensitivity analysis allows management to experiment with possible scenarios.

3. Project definition

The project definition is actually a project plan, in thinned form. It also covers the majority of the business case. This section takes the reader to the what and why of the project or initiative. The first chapter consists of background information about the project, followed by the objectives/ problem. Later sections provide answers to a number of important questions, such as:

What is the SMART Goals of this project?
What is needed to solve the established problem?
How does this project or initiative support the company objectives?

The benefits and limitations of the initiative are also weighed up and incorporated into the document.
Other elements that are reflected in the business case are:

Identification and assessment of alternatives
Reach, impact, and dependencies
Market review
Initial project planning
Risk assessment
Project approach
Purchasing strategy

4. Project organisation

The final section of the business case contains vital information which directly affects the project manager and all members of the organization’s executive team. The document contains two main sections which include information about work package delivery responsibilities and the project’s organizational framework. The section provides detailed information about the following subjects:

Roles and responsibilities
Project standards
Project board
Decision making
Reporting

Example business case: new CRM system

A service provider which operates at a medium scale has identified that its existing CRM system requires modernization. The staff members operate with different lists while information exists in multiple locations which leads to incorrect report generation. The customers receive either multiple follow-up messages or they do not receive any follow-up messages. The current method produces incorrect results which prevent the business from recognizing its market prospects. The business case exists because of this particular situation which needs to be solved.

The analysis phase begins by documenting the existing situation. The organization creates a time allocation map which shows how account managers spend their hours searching for information and tracks customer data errors and identifies sales leads which remain uncontacted. The study analyzes customer complaints which report difficulties in understanding the information that was provided. The document shows the core issue along with its effects on business revenue and customer satisfaction and organizational operational effectiveness.

Various possible solutions are then explored. The options available include maintaining the current system while performing system upgrades and buying a standard cloud CRM solution and building a tailored CRM system. The description of each choice includes total investment costs and product delivery times and necessary organizational resources and supplier involvement requirements.

The cost-benefit analysis identifies which elements will have the most significant impact on the outcome. The cost breakdown for these operations consists of licensing fees and expenses for system deployment and data transfer and employee education and business unit activation. The benefit section shows improved lead tracking which results in better conversion rates and increased cross-selling and upselling and reduced time consumption and decreased occurrence of mistakes. The effects have been measured whenever possible by showing their influence on yearly revenue growth and the amount of business hours that sales teams and back office personnel have saved.

Risks and scenarios are then added. The project faces three main risks which include implementation delays and poor user adoption and management costs that exceed expectations. The business case specifies the control measures which need to be implemented for each risk through pilot programs and phased rollout and training initiatives and defined data and process management responsibilities.

Management can reach a decision through the evidence which supports this matter. The organization selects a standard cloud solution because it provides an optimal combination of cost efficiency and system capabilities and operational adaptability. The business case functions as an active document which guides the project execution instead of becoming an archived document.

The organization conducts a complete evaluation of costs and benefits and risks at every crucial decision point to determine their current status compared to the original business case. The example demonstrates how the business case serves as a continuous connection between the start of the project and its complete execution and assessment.

Business case in agile and innovative environments

Business cases in traditional projects require complete documentation before beginning any work. The process leads to an important choice about which path to take. The method underperforms in agile and innovative work settings according to the information found at https://www.toolshero.com/information-technology/agile-method/”agile/a.” The market operates with high uncertainty because no one has proven their assumptions while both market dynamics and technological progress continue to evolve at a fast pace. The business case should function as a flexible document which develops through experimental results and multiple testing cycles during this process.

Organizations handle their assumptions differently when they first start their operations. The business case depends on innovative concepts which include estimated market demand and predicted customer reactions and calculated expenses and assessed operational viability. The agile approach requires teams to state their assumptions explicitly before they can execute tests to validate these assumptions through multiple steps. The process of testing small pilot projects and experimental initiatives together with minimum viable product development helps identify which assumptions prove to be correct and which ones turn out to be incorrect. The business case undergoes modifications which use actual operational data instead of depending on theoretical models.

People now invest their money through different methods than they used to. Organizations now choose to distribute their funding through multiple stages instead of making a single big investment at the start. The business case shows which objectives will be achieved through each phase and each release while testing specific assumptions and obtaining vital outcomes for upcoming funding rounds. The organization has the ability to change its approach when the results do not meet expectations through concept modifications or complete project termination before using all allocated resources.

For product owners and agile teams, this means that the business case is not just a document for decision-makers, but a reference during the work. The backlog items which produce the most value for achieving the target benefits become apparent during every sprint or iteration. Our team implements customer feedback and usage data information through adjustments to our https://www.toolshero.com/marketing/customer-value-proposition-cvp/”value proposition and we update our cost-benefit analysis when needed.

For clients and steering groups, this way of working requires a different attitude. The process requires specific learning objectives together with defined measurement points and decision-making moments instead of requesting complete advance certainty. The assessment process has transformed from needing a finished business case to determining if our current learning progress during each phase allows us to decide about continuing the project. The business case functions as an essential instrument which provides validation through its evolving directional system instead of using its original form as a fixed initial document.

This method works effectively for organizations which focus on innovation and digital transformation and developing new business models. The business case connection to brief feedback cycles and managed experimental tests decreases potential threats while giving organizations more adaptability. Promising concepts will expand their reach but unsuccessful projects will be terminated through a well-validated assessment process.

Relationship with other models and analyses

The business case does not stand alone. The system operates with multiple models which connect to different analytical tools. These provide support for assumptions and strengthen the arguments presented to decision-makers.

Strategic analyses such as SWOT analysis and PEST analysis provide input for the rationale and context. The market analysis displays both potential market entry points and competitive risks which affect the proposed project implementation.

The financial instruments which include cost-benefit analysis and the ROI and NPV methods enable you to establish precise predictions for the resulting effects. The investment outcome becomes evident through these details which specify the time span and the underlying conditions that apply.

During the development of the project proposal, prioritization and scope can be refined using the MoSCoW method. The document shows which elements must be included in the system and which user needs will become available when there is enough space. The business case connects directly to the RACI Matrix which defines roles and responsibilities for project management.

The model determines which stakeholders receive benefits and which group holds authority to approve modifications and which teams must perform implementation work and perform maintenance tasks. The implementation stage contains a direct connection to risk management and issue management which are essential components of project management.

The business case functions as a central point which connects analysis to decision-making and implementation because the relationship between them has been made clear.

Frequently asked questions about the Business Case

What is the difference between a business case and a business plan?

A business case serves to determine if a particular project or financial commitment should receive approval. The evaluation process centers on four elements which include predicted value together with expenses and potential risks and expected financial gain. A business plan is broader. A business plan shows the operation and development of a business or idea or new activity through multiple future years. The two documents serve different decision-making needs because they operate as separate documents.

Which financial metrics are commonly used in a business case?

Financial metrics make a business case more concrete. The evaluation process determines which benefits will surpass the cost of the project. The main metrics used for evaluation consist of return on investment and net present value and payback period and total costs and expected benefits and sensitivity analysis. The presented numbers enable users to evaluate different alternatives which lead to superior decision-making processes.

Who owns and updates the business case during a project?

In most situations the business case remains under the control of the project sponsor. At the same time, updates often come from the project manager, finance, and other stakeholders. The business case needs to maintain its current status throughout the entire project duration. The organization needs to check this document when costs and risks and expected benefits experience changes to determine if they should proceed with the project or modify their approach or discontinue it.
