BSIS 444 ch 6

____ is a parametric model using dependent variables based upon one or more independent variables that are measures of performance or physical attributes of the system

COCOMO

A WBS represents a logical decomposition of the work to be performed and how the product, service, or result is naturally subdivided

True

The WBS decomposes the projet into smaller components and more managable units of work called work packages

True

in the wbs context, a crux is best described by which of the following?

a proof of concept

The PMBOK area called project time mgmy includes all of the following except

assign activities

____ is the most common, real world method of etimating projects

bottom up

an estimation technique characterized by dividing the project into smaller modules and then directly estimating the time and effort in terms of person-hours, person-weeks, or person months for each module best describes

bottom up estimating

with ____, activity estimates are usually provided by the team members

bottom up estimating

the ___ usually takes more time and costs more

del phi

___ can be very effective and provide reasonable assurance when the stakes are high and the margin of error is low

delphi

an est. technique characterized by the recruitment of multiple experts who provide rounds of estimates

delphi tech.

the first step in accurately estimating an IT app is to

determine the size

with COCOMO ____ projects are challenging in that they may support a new business process or area that is new to the organization

embedded

a screen that alllows the user to input info using a keyboard and a mouse would be called an

external input

something that includes a combination of inputs and outputs for retrieving data from either the internal files or from files external to the application would be called

external inquiry

an entity or data set that includes customer name and addresses that is maintained yb another app system would be called an

external interface file

a mgmt report and its accompanying graphs would be considered a

external output

A tangible and verifiable piece of work is called a milestone

false

COCOMO is an example of a non parametric model because it is characterized by a usually unlimited set of named parameters

false

In much the same fashion as the claim you can never be too rich, when developing a WBS one can never have too much detail in planning activities

false

according to the text, most real world estimating is made using top down estimating

false

counting lines of code is a good way to encourage efficient programming

false

software engineering refers to a broad range of measurements for objectively evaluating computer software

false

the 100 percent rule is the most important criterion in the developing and evaluating WBS. States: the parent element must represent 100 percent of the work applicable to next level decompostiiton of a WBS element

false

the delphi technique is a quick and economical way to estimate the duration and costs of project activities

false

the most common error in guestimating is to be pessimistic and to overestimate the time and resources neccessary to complete a project

false

the use of heuristics is based following immutable principles of project development and lead to highly accurate forecasts

false

function points in a software app program

focus on the functionality and complexity of an app system or module

an estimation charcterized by picking numbers out of the air or ballparking

guesstimating

___ are rules of thumb used to estimate the current project based on prior project experience

heuristics

an erd would be considered a

internal logical file

LOC in a software application program

is easier to account once the program is written that it is to estimate how many lines of code will be required to write the program

confidence in project estimates will be highest _____

later in the project

____ refers to a broad range of measurements for objectively evaluating a computer software

metrics

too much detail in the WBS can lead to

micromanagement

a significant event or achievement that provides evidence that a deliverable is complete is called a

milestone

to be effective each project phase should provide at least

one

with COCOMO __ projects are rountine where the tech, processes and people are expected to work together smoothly

organic

with COCOMO, ___ projects are somewhat challenge and may integrate new processes and technology

semi-detached

____ focuses on the process, tools, and methods for developing a quiality approach to developing software

software engineering

which of the following statements about the WBS is not true

the WBS should be developed by the PM

the 100 percent rule relates to

the next level decomposition of a WBS element must represent 100 percent of the work applicable to the parent element

Project sucess will be determined in large part by _____

thinking carefully through activities and estimating their durations

____ may result in long hours and frustration for the project team

time boxing

an estimation characterized by the allocation of a time frame for a specified activity

time boxing

____ can be very effective estimating technique by forcing examination of a project risks so that a specific budget or schedule targets can be acheived

top down estimating

an estimation technique characterized by schedle and cost estimates of how long something should take or cost

top down estimating

this estimation technique may be driven by an upper mgmt mandate

top down estimating

basing an estimate of activity durations on experience gained from working on similar projects is called analogous estimation

true

because function points are independent of technology they provide a way to compare projects that may use different platforms or languages

true

each phase of the project should provide at least one specific deliverable

true

if the estimates from different estimating techniques are fairly close, then you can average them with a high degree of confidence

true

one way to ensure that the wbs has the appropriate level of detail is to ensure that the people who do the work are involved in its development

true

research suggest that projects that use a formal estimating tool have a better chance of delivering a system that is on time and within budget

true

the three major factors in estimating an IT app are size, complexity, and constraints and influencers

true

time boxing involves allocating a time segment for a task rather than attempting to estimate how long that task should take

true

the WBS is subdivided into smaller components called

work packages
