System modelling
Software Process Modeling
In software process modeling, it is important for us to establish clear statuses and define how one status transitions to another.
For existing systems, we first list all existing statuses detached from previous process logic. This approach allows us to later uncover possible gaps or errors in modeling.
In the second step, the routines or properties of each individual status are documented.
Subsequently, the statuses are analyzed regarding their interdependencies, and the order as well as possible transitions are visualized. The goal of the software model is to provide clear status structures and project-wide uniform signal names, which can also guide software development.
Based on a clearly structured software status model, it is then much easier to formulate clear software requirements. The structure of the model influences the requirements in a way that they describe clear start and end states of a status or routine, and are clearly divisible, testable, and independently workable for backlog planning in development. This allows for improved project organization according to modern models such as SCRUM.

Hardware Modeling
The existing hardware components, their functions, and structure should also be documented in models.
To create meaningful hardware models in the long term, our experts start similarly to software modeling by first listing all available hardware components. This approach also allows for identifying inconsistencies and highlighting gaps during later modeling.
Subsequently, the components are examined regarding their central function in the system.
Next, the components and their functions are divided into logical subsystems and ordered according to the system functionality.
Modeling hardware components and their functionality along their functional chains offers the possibility to formulate corresponding hardware requirements in such a way that their central performance attributes are clearly outlined. Both internal production and external suppliers can later orient themselves based on these attributes.
Our requirements engineers are happy to help you define hardware or software requirements consistently and measurably!
Integration Model: Hardware and Software
An integration model combines the previously described models and takes it a step further. It combines software modeling and hardware models into one, illustrating when communication between software and hardware takes place. This model provides additional information and supplements the previous models with relevant information. It shows when software communicates with hardware in routines and which functions it relies on. On the other hand, the hardware, through its previously defined functions, dictates the possibilities for software to interact with it. By connecting the two systems, gaps can be identified, and products can be optimized.
