The challenge
The subsidiary of a large German automotive supplier used an application lifecycle management (ALM) tool for requirements management of its products and for the management of test cases needed for requirements tracking. Additionally, the company documented the execution of test cycles with the respective results in this tool. However, for the required purposes, the use of the applied tool was limited.
To solve this problem, the company decided to switch to another ALM tool and engaged UL Solutions Software Intensive Systems (SIS) to perform the migration of existing requirements and test artifacts.
For this migration, it was particularly important to maintain the existing links between the individual artifacts or establish new links.
Project duration and resourcing
- Approximately one year
- Two software engineers
Our approach
The existing data first had to be extracted from the old tool. The SIS team developed and implemented different ways to export requirements and test elements respectively.
The exported data was subsequently analyzed and filtered together with the customer, so only relevant attributes were migrated and unnecessary data was skipped or adjusted.
The hierarchy of data structures in the old tool could not be transferred over into the new tool directly, so the SIS team had to find approaches to future data structure development of data structures and mapping that enabled a complete migration and efficiency.
The extracted artifacts were then imported and processed to create equivalent structures in the new software. Subsequently, the links between requirements and the respective test cases were restored for traceability.
During this process, SIS applied agile methods, so the team was able to promptly integrate and implement additional requests and changes from the customer. SIS took over the implementation and the management of the project.
Highlights of our approach
- Process of exporting data.
- Analysis and filtering of data records.
- Creation of new data structures.
Customer benefits
With this approach, the SIS team realized a quick and smooth migration of data from the old tool to the new tool.
The previous filtering of attributes decreased the data records for migration, which in turn will decrease the future work for the customer.
The links between the elements remained intact, creating an interruption-free traceability of requirements.
By switching to the new tool, the customer was able to solve the problems of the previous software and continues the work with the data records, thanks to the complete migration.
Key benefits to our customer included:
- Quick and smooth migration.
- Interruption-free traceability.
- Decrease of data records.
- Same data inventory.
