____ 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
