Question

FROM (Book): Requirements Engineering for Software and Systems edition 3

Please explain:

1- Why the report will consist of data, in sufficient quantity and detail, to meet the requirements. (vague, incomplete, or ambiguous)

2- Why the data provided will allow for a sound determination of the events and conditions that precipitated the failure. (vague, incomplete, or ambiguous)

Answer 1

1. According to the book,

The data reporting is the process of collecting and submitting data which gives rise to accurate analyses of facts on the ground. Inaccurate data reporting can lead to vastly uniformed decision-making based on erroneous evidence. When data is not reported , the problem is known as underreporting ; the opposite problem leads to false positives.

To meet the requirements there are three dimensions of the requirements engineering are identified in namely, the specification , the representation , and the agreement.

• Content : In content all requirements are known and understood in details.
• agreement : Sufficient stackholder agreement is established.
• Documentation : Requirements specification is complaint with the defined format and rules.

The CONTENT dimensions deals with an understanding of the system requirements attained . At the very beginnings of requirements engineering , only a few high level and vague system requirements are known , whereas at the end of the process , all requirements are known and understood at required level of details.

The AGREEMENT dimension deals with the level of agreement achieved among relevant stakeholders about the known requirements . There might be conflict between those individual views.

The DOCUMENTATION dimension deals with documenting and specifying the system requirements using different documentation and specification formats.

2. This book provide the basic conceptual description of engineering.

Hearing allows one to identify and ecognize objects in the world based on the sound they produce , hearing make communication using sound possible.

For occupational hygiene purposes , the sound pressure level is determine noise exprosure.A sound level meter is used for acoustic measurements . It is completely a hand-held instrument with a microphones.
