PROJECT LIFE CYCLE AND EFFORT ESTIMATION
PART A
1. What is SCRUM? (Nov/Dec 2018) (APR/MAY 2018)(NOV/Dec 2019)
Answer:
• Scrum is an efficient framework within which you can develop software with
teamwork. It is based on agile principles.
• Scrum supports continuous collaboration among the customer, team members,
and relevant stakeholders.
2. Expand RAD. Is it incremental model? Justify. (Nov/Dec 2018)
Answer:
• RAD model is Rapid Application Development model. It is a type of incremental
model. In RAD model the components or functions are developed in parallel as if
they were mini projects.
• The developments are time boxed, delivered and then assembled into a working
prototype.
3. Identify the uses of RAD model. (APR/MAY2019)
Answer:
• Rapid application development (RAD) describes a method of software
development which heavily emphasizes rapid prototyping and iterative
delivery.
• The RAD model is, therefore, a sharp alternative to the typical waterfall
development model, which often focuses largely on planning and sequential
design practices.
4. Brief about two ways of setting objectives. (APR/MAY 2018)
Answer:
Software process and Process Models – Choice of Process models - mental delivery – Rapid
Application development – Agile methods – Extreme Programming – SCRUM – Managing
interactive processes – Basics of Software estimation – Effort and Cost estimation techniques –
COSMIC Full function points - COCOMO II A Parametric Productivity Model - Staffing
Pattern.

• For any project to be success , the project objectives should be clearly defined
and the key people involved in the project must known about it. This only
will make them work with single focus and concentration towards achieving
the objectives
• These key people or organisation is called ‘Stakeholder’. A stackholder is
defined as a person or organization who are directly or indirectly affected by
the project .
• A software project is normally complex in nature and would involve many
people draw from various specialities.
• It is always advisable to set sub objectives suitable for every individual or a
group of individuals in line with the main objectives. Sub objectives are more
meaningful to a team so that it is under their control and achievable by them.
• A workable goal setting must always be done using SMART approach.
5. What is rapid application development? (NOV /DEC 2017)
Answer:
RAD or Rapid Application Development process is an adoption of the
waterfall model; it targets at developing software in a short span of time.
RAD follow the iterative method.
SDLC RAD model has following phases
• Business Modeling
• Data Modeling
• Process Modeling
• Application Generation
• Testing and Turnover
6. Outline the advantage of agile unified process. (NOV /DEC 2017)
Answer:
1. Agile methodology has an adaptive approach which is able to respond to the
changing requirements of the clients
2. Direct communication and constant feedback from customer representative leave
no space for any guesswork in the system.

7. What is the function of spiral model? (APR/MAY 2017)
Answer:
• The spiral model is similar to the incremental model, with more emphasis
placed on risk analysis.
• A software project repeatedly passes through these phases in iterations (called
Spirals in this model)
8. What is activity model? (APR/MAY 2017)
Answer:
• The activity model indicates the set of activities needed to turn a set of inputs
(capital, raw materials and labour) into the firm’s value proposition (benefits
to customers).
• Examples of such activities include product development, purchasing,
manufacturing, marketing and sales and service delivery.
9. What is a software process model?
Answer:
• A Process Model describes the sequence of phases for the entire lifetime of a
product.
• Therefore it is sometimes also called Product Life Cycle.
• This covers everything from the initial commercial idea until the final de-
installation or disassembling of the product after its use.
10. What were the phases in software process model?
Answer:
• There are three main phases:
∗ Concept phase
∗ Implementation phase
∗ Maintenance phase
• Each of these main phases usually has some sub-phases, like a requirement
engineering phase, a design phase, a build phase and a testing phase.
• The sub-phases may occur in more than one main phase each of them with a
specific peculiarity depending on the main phase.

11. List various software process models.
Answer:
• Waterfall model,
• Spiral model,
• V-model,
• Iterative model,
• Agile model and RAD model.
12. Define Agile Methods.
Answer:
• Agile model is a combination of iterative and incremental process models with
focus on process adaptability and customer satisfaction by rapid delivery of
working software product.
• Agile Methods break the product into small incremental builds. These builds
are provided in iterations. Every iteration involves cross functional teams
working simultaneously on various areas like planning, requirements
analysis, design, coding, unit testing, and acceptance testing.
13. List out the various agile approaches.
Answer:
• Crystal Technologies
• Atern(formerly DSDM)
• Feature-driven Development
• Scrum
• Extreme Programming(XP)
14. What is extreme programming?
Answer:
• Extreme programming (XP) is a software development methodology, which is
intended to improve software quality and responsiveness to changing
customer requirements.

Page 5
• As a type of agile software development, it advocates frequent "releases" in
short development cycles, to improve productivity and introduce checkpoints
at which new customer requirements can be adopted.
15. Write about COCOMO model.
• Constructive Cost Model.
• It refers to a group of models.
• The basic model was built around the equation:
Effort=c*sizek,
• Where effort is measured in pm,or the number of ‘person-months’.
16. Define organic mode.
Answer:
• Organic mode is the case when relatively small teams developed software in a
highly familiar in-house environment and when the system being developed
was small and the interface requirements were flexible.
17. Give an idea about parametric model?
Answer:
• Models that focus on task or system size. Eg.Function Points.
• FPs originally used to estimate Lines of Code, rather than effort
• Models that focus on productivity: e.g. COCOMO
• In this Lines of code (or FPs etc) is an input

Page 6
18. What is the use of COCOMO model and its types?
Answer:
• COCOMO predicts the effort and schedule for a software product development
based on inputs relating to the size of the software and a number of cost
drivers that affect productivity.
• COCOMO has three different models that reflect the complexity:
• The Basic Model
• The Intermediate Model
• The Detailed Model
19. Write any two advantages of function point analysis.
Answer:
• Improved project estimating
• Understanding project and maintenance productivity
• Managing changing project requirements
• Gathering user requirements.
20. Define application composition.
Answer:
• In application composition the external features of the system that the users
will experience are designed. Prototyping will typically be employed to do this
with small application that can be built using high-productivity application
building tools, development can stop at this point.
21. Determine the stages of estimation carried out in a software project.
(APR/MAY2019)
1. Scoping.

Page 7
2. Decomposition.
3. Sizing.
4. Expert and Peer Review.
5. Estimation Finalization.
22) Give example for rapid application development.
Some of the tools that can be used in RAD are those that are strong in
automated code generating, such as:
Super Mojo by Penumbra.
Microsoft Lightswitch.
Visual Studio.
Wavemaker.
Delphi RAD studio.
Lazarus IDE.
PART B
1) How the cost- estimation of Agile projects are done? Explain in detail
(Nov/Dec 2018) (13m)
Answer:
• Agile software development methodology is a process for developing software
(like other software development methodologies – Waterfall model, V-Model,
Iterative model etc.)
• However, Agile methodology differs significantly from other methodologies. In
English, Agile means ‘ability to move quickly and easily’ and responding
swiftly to change – this is a key aspect of Agile software development as well.
• Cost estimation in software engineering is the process of predicting the
resources (money, time, and people) necessary to finish a project within
the defined scope.
• Accurate estimates help everyone involved in the project: Project owners
can decide whether to take on the project
Brief overview of Agile Methodology
Why agile estimates?
There are two generally accepted methodologies for developing software:
waterfall, also known as the traditional model, and agile. Their
approaches to estimating projects are quite different. At Steelkiwi, we follow
