This information generally includes the environment of the customer, when and how the issue occurs, and all other relevant circumstances. The technician will also ensure that enough information about the problem is obtained from the customer. (2) The technician verifies that the problem is real, and not just perceived. Some applications provide built-in messaging system and automatic error reporting from exception handling blocks. (1) A customer service technician receives a telephone call, email, or other communication from a customer about a problem. 'An example scenario is presented to demonstrate how a common issue tracking system would work:

The vector stencils library 'Sequence diagram' is included in the SysML solution from the Software Development area of ConceptDraw Solution Park. It should be the result of a message, either from the object itself, or another.Ī message sent from outside the diagram can be represented by a message originating from a filled-in circle (found message in UML) or from a border of the sequence diagram (gate in UML).' When an object is destroyed (removed from memory), an X is drawn on top of the lifeline, and the dashed line ceases to be drawn below it (this is not the case in the first example though). Objects calling methods on themselves use messages and add new activation boxes on top of any others to indicate a further level of processing. Activation boxes, or method-call boxes, are opaque rectangles drawn on top of lifelines to represent that processes are being performed in response to the message (ExecutionSpecifications in UML). Asynchronous calls are present in multithreaded applications and in message-oriented middleware. If a caller sends an asynchronous message, it can continue processing and doesn’t have to wait for a response. If a caller sends a synchronous message, it must wait until the message is done, such as invoking a subroutine. Solid arrow heads represent synchronous calls, open arrow heads represent asynchronous messages, and dashed lines represent reply messages. Messages, written with horizontal arrows with the message name written above them, display interaction. Leaving the instance name blank can represent anonymous and unnamed instances. If the lifeline is that of an object, it demonstrates a role. This allows the specification of simple runtime scenarios in a graphical manner. 'A sequence diagram shows, as parallel vertical lines (lifelines), different processes or objects that live simultaneously, and, as horizontal arrows, the messages exchanged between them, in the order in which they occur.
