Question { CA, 4758 }

who does the estimation in perticular SW project

Answer

Over all project estimation will be done by PM, technical
estimation will be taken care by technical leader,
functional will be taken care by functional specialist.

Question { IBM, 4229 }

what are the parameters / dependencies in calculating the
estimation

Answer

Based on FP (Functional Points) count only we will
calculate the estimation this will be changed based on
Front end & Back end technology

Answer

We have 10 check points to review the Estimations.

1. Define Scope & Purpose
2. Identify Technical Baseline and GR&A
3. Collect Data
4. Software Sizing (new and reused)
5. Prepare Baseline Estimate
6. Identify Risk items
7. Estimate Validation and Review
8. Build a Project Plan
9. Document Estimate
10. Track Project

Question { Analogue Systems, 3840 }

is there any limitations for holystic estimation

Answer

Estimation is a crucial element of software project
planning. Unfortunately, there are inherent limitations in
the ability to estimate projects accurately due to the
inherent uncertainties in software projects.

In 1968, Alfred Pietrasanta of IBM System Research
Institute wrote, "Anyone who expects a quick and easy
solution to the multifaceted problem of resource estimation
is going to be disappointed." Thirty years later, Lionel
Briand and his colleagues observed that "Despite the large
number of cost factors collected and the rigorous data
collection, a lot of uncertainty in the estimates can be
observed" (Briand et al., "An Assessment and Comparison of
Common Software Cost Estimation Methods," Proc. Int'l Conf.
Software Eng., [ICSE], IEEE 1999, pp. 313322). It's now
2006, and we still have problems with estimation.

Question { First National Bank, 31612 }

what is the difference between waterfall model and
SDLC(system development life cycle) ?

Answer

The waterfall model is a popular version of the systems
development life cycle model for software engineering.

The above question is wrong.

you can ask difference between waterfall model and joint
application development model(JAD) or rapid application
development model(RAD) and the spiral model etc.,
