What belongs in a specification sheet for an IT project and how do I formulate it?

– A guide. –

1. purpose and aim of the specifications

The specifications define:

• What is to be achieved (requirements and objectives of the project).
• Why the project is being carried out (client’s objective).
• For whom the project is being realized (target group).

Example for the introduction: “The requirements specification describes the requirements for the development of a new software solution for the automation of business processes in area X. The aim is to increase the efficiency of processes and improve user-friendliness.”

2. structure and organization of a specification sheet

A good specification follows a clear structure. It helps to make the content clear and easy to understand. The typical structure of a specification sheet is as follows:

1. Introduction
2. Objective
3. Actual state
4. Target state
5. Requirements for the system
6. General conditions and constraints
7. Functional requirements
8. Non-functional requirements
9. Use cases and user groups
10. Interfaces and dependencies
11. Scheduling and milestones
12. Budget and resources
13. Appendix

3. detailed contents of a specification sheet

3.1 Introduction

The introduction describes the general context of the project and the reason for its implementation. It briefly outlines the purpose of the project and the intended goal.

Example: “This specification serves as the basis for the development of a web application that is intended to optimize internal communication within the company.”

3.2 Objective

The objective explains which overarching goal is to be achieved by the project. You should define precise and measurable goals here.

Example: “The aim of the project is to develop a web application that makes internal communication at least 20% more efficient by providing a central platform.”

3.3 Current status

This is where you describe the current state of affairs. It is about analyzing the existing system or process and identifying the weak points.

Example: “Communication within the company currently takes place via various channels such as email and instant messaging, which leads to fragmentation of information and inefficient document storage.”

3.4 Target state

The target state describes what the situation should look like once the project has been successfully implemented. It should be clear here what improvements and changes are expected.

Example: “The planned web application is intended to provide a central platform for all employees that simplifies communication processes, enables structured document storage and increases transparency in projects.”

3.5 Requirements for the system

This is where you define general requirements for the system or solution. This includes technical, organizational or content-related requirements.

Example: “The system must be web-based so that it can be used on different devices regardless of the platform. There should also be LDAP integration for user administration.”

3.6 General conditions and boundary conditions

In this section, you describe the framework conditions that must be taken into account during implementation. These include legal requirements, standards and technical limits.

Example: “The solution must comply with the GDPR guidelines and run on the company’s existing server structures.”

3.7 Functional requirements

The functional requirements specify the functions that the system must offer. These are the core functions of the planned solution.

Example:

• “The system should offer a chat function for all employees.”
• “There must be calendar integration to coordinate appointments.”
• “Documents must be able to be uploaded and categorized in the application.”

3.8 Non-functional requirements

Non-functional requirements define qualitative requirements, such as performance, user-friendliness or security.

Example:

• “The system must support at least 1000 simultaneous users.”
• “The response time when navigating through the system must not exceed 2 seconds.”
• “The system must have an availability of 99.9 %.”

3.9 Use cases and user groups

In this section, describe how different user groups will use the system and which use cases are envisaged.

Example: “There are three user groups: Administrators, project managers and employees. Employees should be able to access the chat and file functions, while administrators have additional rights to create and manage user accounts.”

3.10 Interfaces and dependencies

Here you can list all interfaces to other systems or software solutions that need to be integrated or connected.

Example: “The web application must be connected to the existing ERP system and the central database.”

3.11 Scheduling and milestones

An overview of the planned project steps and milestones helps to define the time frame and pursue the project goal.

Example:

• “Phase 1: Requirements analysis (2 weeks)”
• “Phase 2: Development of the prototype (6 weeks)”
• “Phase 3: Test phase (4 weeks)”
• “Go-live: Q3 2024”

3.12 Budget and resources

In this section you describe the planned budget and the available resources (personnel, hardware, software).

Example: “The project budget is 100,000 euros. Four developers, one project manager and two IT administrators are available for implementation.”

3.13 Appendix

The appendix contains all additional information, such as diagrams, technical specifications, process descriptions or reference documents.

4. formulation tips for the specification sheet

• Formulate clearly and precisely: Use short, concise sentences to avoid misunderstandings.
• Explain technical terms and abbreviations: If you use special terms, make sure that they are clearly defined.
• Measurable goals and requirements: Formulate requirements and goals in such a way that they are measurable and verifiable.
• Avoid assumptions: Every requirement should be formulated clearly and without room for interpretation.

Conclusion

A well thought-out and clearly formulated specification sheet is crucial for the success of an IT project. It creates transparency and ensures that everyone involved understands the requirements and objectives of the project.
