Document Summary

1/23 lecture a. b. c. d. e. f. System: collection of hardware, software, people, facilities, and procedures organized to accomplish a common objective. Systems engineering: design, production, and maintenance of trustworthy systems within cost and time constraints. Steps in design: concept of operations, high level requirements, detailed requirements, high level design, detailed design. Steps in implementation: integration/test, subsystem verification, system acceptance, operations/maintenance, retirement/disposal. Concept of operations: stakeholder"s pov< goal, constraints, roles/responsibilities. Requirement: statement of what, how well, and under what conditions something must be done: use shall , structured english, numbered sentences, figures, positive/compound, metrics: morq (measurable, observable, repeatable, quantifiable h. Each requirement should: be testable, provide useful function/services, present an acceptable risk if placed in operations i. Systems development documentation: concept of operations description ii. System requirements specification: hardware/software requirements specification (unit level) Interface design description vii: database design description ix. Software user manual (procedures) followed by operating/training manuals j. k. 64% errors occur in analysis/design, 36% in coding.
