It is essential to align the system objectives with the overall goals and objectives of the organization. This alignment helps in achieving strategic alignment and ensures that the system contributes to the organization's success. Designers should consider factors such as:

• Organizational mission and vision
• Key performance indicators
• Business processes and workflows

By aligning the system objectives with these factors, designers can ensure that the new system adds value and supports the organization's strategic direction.

Establish System Constraints

After defining the system objectives, designers need to establish the constraints that the system must adhere to. These constraints can include factors such as budget, time, resources, and technology.

Identifying the Limitations and Constraints

Designers should identify the limitations and constraints that may impact the system design and development process. Some common constraints include:

• Budgetary limitations
• Time constraints
• Resource availability
• Technological limitations

By identifying these constraints, designers can make informed decisions and develop a design that is feasible and realistic.

Considering Factors

Designers need to consider various factors when establishing system constraints. These factors include:

• Time: The project timeline influences the design process and determines the feasibility of implementing certain features or functionalities.
• Resources: The availability of skilled personnel and infrastructure impacts the design decisions.
• Technology: The existing technological infrastructure and compatibility with the new system need to be considered.

By considering these factors, designers can ensure that the system design is aligned with the available resources and constraints.

Determine Information Needs

The next step in Conceptual System Design is to determine the information needs of the system. This involves identifying the types of data and information that need to be captured, processed, and stored.

Identifying Information Requirements

Designers should identify the specific information requirements of the system. This includes:

• Data inputs: The types of data that need to be collected and entered into the system.
• Data processing: The calculations, transformations, and manipulations that need to be performed on the data.
• Data outputs: The types of reports, dashboards, or visualizations that need to be generated.

By identifying these information requirements, designers can ensure that the system captures and processes the necessary data to support decision-making and operational needs.

Understanding Data and Information Types

Designers should have a clear understanding of the different types of data and information that the system will handle. This includes:

• Structured data: Data that is organized and stored in a predefined format, such as a database.
• Unstructured data: Data that does not have a predefined structure, such as emails, documents, or social media posts.
• Internal data: Data that is generated and collected within the organization.
• External data: Data that is obtained from external sources, such as market research reports or government databases.

By understanding these data and information types, designers can ensure that the system is capable of handling and processing the required data.

Determine Information Sources

Once the information needs have been determined, designers need to identify the internal and external sources of information that will feed into the system.

Identifying Internal Sources

Designers should identify the internal sources of information within the organization. This includes:

• Existing databases and systems
• Internal documents and reports
• Employee-generated data

By identifying these internal sources, designers can ensure that the system integrates seamlessly with the existing information infrastructure.

Evaluating Information Reliability and Availability

Designers should evaluate the reliability and availability of the information sources. This involves assessing factors such as:

• Data accuracy: The degree to which the data is free from errors or inconsistencies.
• Data completeness: The extent to which the data captures all the relevant information.
• Data timeliness: The freshness and currency of the data.

By evaluating these factors, designers can ensure that the system relies on accurate and up-to-date information.

Develop Alternative Conceptual Designs and Select One

Based on the defined objectives, constraints, information needs, and sources, designers need to develop multiple alternative conceptual designs for the system. These designs should be evaluated based on their pros and cons before selecting the most suitable one.

Generating Design Options

Designers should brainstorm and generate multiple design options for the system. This can involve:

• Creating system flowcharts and diagrams
• Designing user interfaces and screens
