As mystical and beyond comprehension
According to the text, what have most of the software effort estimation methods not done until now?
Gone beyond research and academic applications
What does the author propose in the chapter regarding existing software effort estimation methods?
A schema for their classification
What is the primary basis for grouping effort estimation methods in Fig. 6.1?
The type of data they use as input
What characterizes proprietary effort estimation methods?
They are not fully documented in the public domain
According to the text, why are some estimation approaches not disclosed to the public?
Because of the proprietary character of industrial data
What does Tom DeMarco's quote imply about transportable cost models?
They do not exist for cost forecasting in a specific shop
Which principle is used to group effort estimation methods in Fig. 6.1?
The estimation principle they employ
What is the distinguishing factor of non-proprietary effort estimation methods?
They are fully disclosed in the public domain
Why are some estimation algorithms not disclosed to the public according to the text?
Due to the proprietary character of underlying fixed estimation model or industrial data
'Guesstimation', 'Analytic Hierarchy Process', and 'Stochastic Budget Simulation' belong to which group of effort estimation methods?
'Hybrid' group
What is Tom DeMarco's opinion regarding waiting for others to develop cost forecasting formulas?
It is a waste of time and resources
What is one of the reasons for failed estimates according to the text?
Insufficient background of estimators in software estimation
What is the primary focus of the chapter regarding software effort estimation?
Optimizing software project scope and resources
What is the underlying issue with arbitrary selection and blind usage of estimation methods and tools?
Disappointing outcomes with unclear reasons
What is the characteristic purpose of effort estimation as mentioned in the text?
Optimizing software project scope and resources
What does corporate management sometimes suggest when discussing effort estimation, according to the text?
"Think of a number and multiply by three"
Why is knowledgeable use of estimation methods important according to the text?
To avoid disappointing outcomes in estimation
What is the author's opinion on using estimates as internal project targets and providing them to customers as bids?
Estimates should be used as internal project targets but not provided to customers as bids.
How is an estimate traditionally considered?
In deterministic terms, as a single value.
What does the author suggest about using the most optimistic prediction as an estimate?
It may have fatal consequences in practice.
According to Tom DeMarco, what is a better definition for 'estimate'?
A prediction that is equally likely to be above and below the actual result.
What does the Project Management Institute (2013) define as the estimation objective?
Providing an approximation of the resources needed to complete project activities and deliver outputs.
How are range estimates proposed in order to account for estimation uncertainty?
By representing estimates by a range and/or distribution of possible effort values.
What is the distinction between point estimates and range estimates?
Point estimates represent a single value, while range estimates represent a range and/or distribution of possible effort values.
Why does the author caution against uncritically selecting the most optimistic prediction as an estimate?
Because it may easily result in running a software project into high risk of overrunning initial estimates.
What does the author suggest about using estimates in practice?
Use estimates that represent predictions with highest probability of becoming true.
What is the primary basis for grouping effort estimation methods according to the text?
Known project risks such as little domain experience of the development team.
What trend does the text observe in newly proposed software effort estimation methods?
The trend of considering estimates in terms of range and/or distribution of possible effort values.
