ATI's Systems Engineering—Universal Architecture Description Framework course

Share |


    Technical Training Short On Site Course Quote

      This three-day course closes the door on a task long neglected by system and software engineers and opens a door that will lead to tremendously improved requirements analysis capability for enterprises that choose to implement the techniques covered. The course finally accomplishes integration and optimization work on the many models that have been developed, none of which are comprehensive. Several comprehensive UADF are offered that an enterprise can focus its specification development work on using modeling as the source for all requirements. A universal specification format that is coordinated with modeling methods is also encouraged.

    What You Will Learn:

    • The most effective specification develop-ment method using a set of comprehensive models that will expose every essential characteristic (require-ment) for every part of every system your teams will become involved in developing.
    • Specific modeling methods proven effective on real programs.
    • How to capture the modeling basis for an architecture such that it can be affordably configuration managed.

      From this course you will learn how to accomplish all of the requirements analysis work on all of your programs using a universal set of models that will encourage identification of all essential characteristics.

    Course Outline:

    1. Introduction to System Definition

    2. Requirements Fundamentals

    3. Architecture and Modeling

    4. Functional Analysis Opens a discussion of the problem space component of traditional structured analysis (TSA) with functional analysis extending over periods 4 through 10. TSA is one of the components from which we can select modeling artifacts for our UADF.

    5. Functional Analysis (Continued)

    6. Performance Requirements Analysis and the RAS - Performance requirements are derived from functions and allocated to physical product entities in a requirements analysis sheet (RAS).

    7. Product Entity Structure Synthesis - The remaining modeling that is necessary is solution space oriented and starts with a clear understanding of what the system must consist of.

    8. Interface Identification and Definition

    9. Specialty Engineering Requirements

    10. Environmental Requirements

    11. MSA and PSARE Modern structured analysis is an early and effective software modeling method that was improved on significantly by Deriek Hatley and Imtiaz Pirbhai who extended it to cover real-time systems as well as systems and hardware.

    12. MSA and PSARE (Continued)

    13. UML and SysML These two modeling methods were what encouraged the identification of an entity called a UADF. However, even though SysML extends UML to systems and hardware, they are not comprehensive.

    14. UML and SysML (Continued)

    15. IDEF and DoDAF Neither IDEF or DoDAF are proposed as components in a UADF in this course, they are presented here for completeness and many firms may find it necessary to employ DoDAF on military programs.

    16. IDEF and DoDAF (Continued)

    17. Introduction to UADF

    18. Universal Specification How to structure all specifications so that their content will be traceable to the modeling work from which they were derived.

    19. TSA/MSA UADF Many companies may still be using these modeling methods in an uncoordinated fashion. These two periods show how they can be integrated into a single UADF. A common solution space modeling set is grafted onto the set.

    20. TSA.MSA UADF (Continued)

    21. SysML/UML UADF These two periods team the most recently developed models with a set of common solution space models to form a UADF.

    22. SysML/UML UADF (Continued)

    23. PSARE UADF The work of Hatley and Pirbhai actually provides us with a single comprehensive UADF but we will graft onto it a common solution space modeling approach.

    24. Management Infrastructure and the Future There are exciting things that will be happening in our near term future as industry moves into model driven development that will require more effective command of problem space and solution space modeling work. The final step in movement to UADF will involve a closer coordination of descriptive modeling and executable modeling.


      Tuition for this three-day course is $1590 per person at one of our scheduled public courses. Onsite pricing is available. Please call us at 410-956-8805 or send an email to
