Introduction

Taxonomy sources:
  • Barbacci, Mario; Klein, Mark H.; Longstaff, Thomas A.; and Weinstock, Charles B. "Quality Attributes", SEI Technical Report, CMU/SEI-95-TR-021, December 1995.
  • Karl E. Weigers

"Performance is that attribute of a computer system that characterizes the timeliness of the service delivered by the system."

Concerns
IDAttributeConcern
PE-01 Response Time How long does it take the system to satisfy requests?
PE-02 Latency How can the demand and resources change over time? What happens when system capacity is exceeded and not all events can be responded to in a timely manner?
PE-03 Throughput To how many events can responses be produced over a given interval of time?
PE-04 Dynamic Capacity How much demand can be placed on the system while continuing to meet latency and throughput requirements?
PE-05 Static Capacity How many entities of a particular type can the system store?
PE-06 Modes How can the demand and resources change over time? What happens when system capacity is exceeded and not all events can be responded to in a timely manner?

Response Time

Nothing to say at this time.

Latency

Nothing to say at this time.

Throughput

PE-03.01 Blood pressure measurement rate: The system shall be able to measure blood pressure at a rate of at least one measurement per second.
PE-03.02 Heart rate measurement rate: The system shall be able to measure heart rate at a rate of at least one measurement per second.

Dynamic Capacity

Needs more work!
PE-04.01 The system shall be able to measure blood pressure at least once per cardiac cycle of ?-180 bpm.
PE-04.02 The system shall be able to measure heart rate range from ?-180 bpm.

Static Capacity

PE-05.01 Total blood pressure capacity: The system shall be able to retain a minimum of 336 blood pressure measurements. Explanation: 7 days of data, acquired once every 30 minutes.
PE-05.02 Total heart rate capacity: The system shall be able to retain a minimum of 336 heart rate measurements. Explanation: 7 days of data, acquired once every 30 minutes.

Modes

Nothing to say at this time.
