There are no real differences between creating WebApps and Mobile-Apps 1

In its simplest form an external computing device may access cloud data 1

Product line software development depends the reuse of existing software 1
components to provide software engineering leverage.
Agility is nothing more than the ability of a project team to respond rapidly to 1
change.
In agile software processes the highest priorities is to satisfy the customer 1
through early and continuous delivery of valuable software.

In agile development it is more important to build software that meets the 1

customers’ needs today than worry about features that might be needed in
the future.
All agile process models conform to a greater or lesser degree to the 1
principles stated in the “Manifesto for Agile Software Development”.

The Dynamic Systems Development Method (DSDM) suggests a 1

philosophy that is based on the Paretoprinciple (80% of the application can
be delivered in 20% of the time required to build the complete application).

Agile Unified Process uses the classic UP phased activities (inception, 1

elaboration, construction, transition) to helpthe team visualize the overall
process flow.
Human aspects of software engineering are not relevant in today’s agile 1
process models.
Group communication and collaboration are as important as the technical 1
skills of an individual team member to the success of a team

Teams with diversity in the individual team member skill sets tend to be 1
more effective than teams without this diversity.
Software engineering team structure is independent of problem complexity 1
and size of the expected software products.
Agile teams are allowed to self-organize and make their own technical 1
decisions.
In XP a metaphor is used as a device to facilitate communications among 1
customers, team members, and managers?

Using an established social media platform negates the need to be 1

concerned about privacy or security
Use of cloud services can speed up information sharing among software 1
team members?
In collaborative development environments, metrics are used to reward and 1
punish team members
Process technology tools allow software organizations to compress 1
schedules by skipping unimportant activities.
It is generally accepted that one cannot have weak software processes and 1
create high quality end products.
The communication activity is best handled for small projects using six 1
distinct actions (inception, elicitation, elaboration, negotiation, specification,
validation).
A good software development team always uses the same task set for every 1
project to insure high quality work products.
Software processes can be constructed out of pre-existing software patterns 1
to best meet the needs of a software project
In general software only succeeds if its behavior is consistent with the 1
objectives of its designers.
Agility is nothing more than the ability of a project team to respond rapidly to 1
change.
In agile software processes the highest priorities is to satisfy the customer 1
through early and continuous delivery of valuable software.

Software engineering principles have about a three year half-life. 1

Every communication activity should have a facilitator to make sure that the 1
customer is not allowed to dominatethe proceedings.

The agile view of iterative customer communication and collaboration is 1

applicable to all software engineering practice
Project plans should not be changed once they are adopted by a team 1

The design model should be traceable to the requirements model 1

Teams using agile software practices do not generally create models 1

A successful test I ones that discovers at least one as-yet undiscovered 1

error.
Larger programming teams are always more productive than smaller teams. 1

Increasingly, organizations adopt and follow a standardized systems 1

development process
The number and scope of phases and activities in a methodology varies 1

A directive is a new requirement that's imposed by management, 1

government or some external influence
Opportunities are chances to improve the organization in the absence of 1
specific problems
By dividing a larger problem (system) into more easily manage pieces 1
(subsystems); the analyst can simplify the problem-solving process.

The first solution an analyst finds is usually the best solution. It is not cost 1
effective to consider alternatives
Project management ensures that an information system is developed at 1
minimum cost, within a specific time frame, and with acceptable quality
 The most common reason for software project failure is lack of functionality 1

In requirements validation the requirements model is reviewed to ensure its 1

technical feasibility.
In win-win negotiation, the customer’s needs are met even though the 1
developer’s need may not be.
In agile process models requirements engineering and design activities are 1
interleaved.
Analysis patterns facilitate the transformation of the analysis model into a 1
design model by suggesting reliable solutions to common problems

Use-case actors are always people, never system devices. 1

Developers and customers create use-cases to help the software team 1
understand how different classes of end-users will use functions

User stories are complete descriptions the user needs and include the non- 1
functional requirements for a software increment.
User stories are complete descriptions the user needs and include the non- 1
functional requirements for a software increment.
Non-functional requirements can be safely ignored in modern 1
It is relatively common for different customers to propose conflicting 1
requirements, each arguing that his or her version is the right one.

A stakeholder is anyone who will purchase the completed software system 1

under development. Answer is
Requirements engineering is a generic process that does not vary from one 1
software project to another.
Software engineering doesn’t concern with customer problem 1
in vlaue based view the quality is related to the amount the customer is 1
