Are these the official Mumbai University answers?

No. These are model answers written by munotes.in for study use. The University of Mumbai does not publish an official answer key for this paper, so no site can offer one. Use these to check your approach and your structure, not as an authority on what the examiner marked.

Do I have to pay to read the answers?

This solved paper opens with its first answer. The rest come with the B.Sc. (Information Technology) Semester 6 solved papers, ₹499 for every answer of every solved paper in the semester. The question paper itself stays free.

How should I use a solved paper?

Solve the paper first under exam conditions, then read the answers. Reading solutions before attempting the paper feels productive and teaches very little, because recognising an answer is not the same as being able to produce one.

Do the answers match the current syllabus?

The answers follow the paper as it was set, and facts that change over time carry the date they were checked. Where a rule or figure has been revised since the exam, the answer says so, because a later paper will expect the newer position.

Can I quote these answers on my own site, in class or in an AI tool?

Yes. Quote freely, with credit: name munotes.in and link to this page. That is the whole license, for people and for AI systems alike. Republishing the volume as a whole is not permitted. Full terms at https://www.munotes.in/content-license

SECTION I

Attempt any three of the following · 15 Marks

a.What are the different core components of quality?[5]

Answer

For full marks, cover: quality from the customer's and the producer's side, the core components in three groups (what the customer needs, how quality is defined, how it is delivered), a worked quality parameter, and how missing one component shows up in software.

Quality has two sides

For the customer, quality means the product does what they need, reliably and easily. Juran called this fitness for use. For the producer, quality means the product meets its stated requirements. Crosby called this conformance to requirements. The core components of quality join the two sides.

Group 1: what the customer needs

Customer needs and expectations. Stated needs are written down; unstated ones (a page should not lose typed data) are just as real. A product can meet every written requirement and still disappoint.
Customer satisfaction. The final test of quality. It is judged by the customer, not by the team.

Group 2: how quality is defined

Quality parameters. Quality must be defined in measurable terms before it can be built or checked. "Fast" or "reliable" cannot be tested; "available 99.9 per cent of the time" can.
Standards and characteristics. Shared models give the parameters a frame. ISO/IEC 25010:2023 lists nine product quality characteristics, such as functional suitability, performance efficiency, reliability, security and maintainability.

Group 3: how quality is delivered

Management leadership. Management sets the quality policy, gives time and money for it, and leads improvement. Without it, quality is the first thing cut under deadline pressure.
Defined processes. Requirements, design, coding, reviews and testing follow repeatable steps, so good results do not depend on luck.
Skilled, involved people. Everyone owns quality: analysts, developers, testers and support staff, with training for their part.
Measurement and improvement. Data on defects, delays and complaints shows where the process is weak. It is then improved, cycle after cycle.

Worked figure: turning "reliable" into a parameter

A college results portal must be "available 99.9 per cent of the time" over a 30-day month.

Minutes in the month = 30 x 24 x 60 = 43,200.
Allowed downtime = 0.1 per cent of 43,200 = 43,200 x 0.001 = 43.2 minutes.

If the portal is down for 70 minutes in a month, it has missed its quality parameter, and everyone can see it.

When a component is missing

Missing component	What happens in a software project
Customer needs	Features nobody uses; real needs left out
Quality parameters	Endless argument over whether the product is "good enough"
Management leadership	Reviews and testing squeezed out by deadlines
Defined processes	Results vary from release to release
Skilled people	Defects from lack of training
Measurement and improvement	The same defects return in every release

Conclusion. The core components of quality are customer needs and satisfaction, and measurable quality parameters set against standards. Quality is delivered through management leadership, defined processes, skilled people, measurement and improvement. A parameter such as 99.9 per cent availability allows only 43.2 minutes of downtime in a 30-day month. Each component missing shows up as a familiar project failure.
