as 1 - Statistical, 2 - Quality and 3 - Measurement
approaches.
MSChart consists of modules: presentation
(introduction), login, data collection, storage,
analysis and management, ST and SPC parameters,
design of control charts; data acquisition, data
processing, control chart design (choice of control
charts) and specification of statistical tolerance
(definition of control limits, quality indexes,
statistical tolerance and design of control charts). The
work (Zhang and Hou, 2010) does not describe an
example of tool use.
5.8 PAS System (Process Analysis
System)
The Process Analysis System (PAS) was developed
to meet the needs of small and medium enterprises of
the software manufacturing industry in the use of
quality control and the SPC. The PAS system
encourages the use of SPC, aims to reduce costs,
provides several types of control charts and accepts
most types of data (Chang and Lee, 2013). Its main
functionalities are: web service, user types, doubts
page, scenario choice (control chart type), type of
data storage and system procedures (history and data
configuration). It is considered as 1 - Statistical, 2 -
Quality and 3 - Measurement approaches.
The work (Chang and Lee, 2013) describes an
example of using the PAS system, where the user
initially defines the characteristics of the process, data
type and control chart to be analyzed. It then
configures the data to be inserted and can be viewed
and filtered into tables. The user must define the
number of data of each subgroup and the way the
system will calculate the generated data.
Subsequently, the charts are generated for analysis.
Data can be entered and changed at any time. If there
are more general doubts, the user can access the
"doubts" field, or in cases of doubts related to control
charts, the user must access "Control Guide". For

6 THE EVALUATION OF
SOFTWARE TOOLS
CATALOGUE
The catalogue of approaches was evaluated by means
of a peer review method. In this method one or more
experts of the researched area evaluate the study,
observing its relevance, correctness and contributing
with considerations for its improvement. Its choice is
justified by the need for a expert, who understands the
information provided in the catalogue, who has
experience in the area in question, can contribute to
the refinement of the catalogue and in the future put
it under evaluation in the industry.
This catalogue was evaluated by an expert in the
Software Engineering, Master in Computer Science
at Software Process Improvement (SPI), MR-MPS-
SW consultant and evaluator and with experience in
implementation, consulting and evaluation in
Software Process Improvement of more than 10
years, according to the models of CMMI and
MPS.BR – Brazilian Software Process Improvement,
and with more than 5 years experience with the use of
Statistical Process Control.
For the evaluation of the catalogue an evaluation
questionnaire was created, composed of 16 objective
questions, divided into 2 groups: the first one
concerns the Profile of the Reviewer of the catalogue,
in which the questions aim to discover the level of
knowledge of the reviewer regarding of the
methodology, process improvement of the
implementation the SPC, implementation of models
for process improvement, methods of evaluation in
the models and time of experience in evaluation of
SPC processes.
The second group deals with the Proposal
Presentation, whose purpose is to verify the
evaluator's understanding of the work under
evaluation, having as a matter of fact the degree of
correctness and completeness of the catalogue and if
it can be used as a reference in aiding the
implementation of the SPC.
As an annex to the questionnaire, a subjective
evaluation was requested to review the submitted
material, based on (Neto et al., 2017), in which it was
allowed to record comments by a table filled out by
the evaluator, containing the identification of the
comment, its category (HT - High Technician,
indicating that a problem has been found in an item
that, if not changed, will compromise the
considerations; LT - Low Technician, indicating that
a problem has been found in an item that it would be
appropriate to change; , indicating that a Portuguese
error was found or that the text could be improved; Q
- Questioning, indicating that there were doubts as to
the content of the considerations; G - General,
indicating that the comment is general in relation to
the considerations, item a which corresponds (which
can be related to a phase, task or in general of the
catalog), the text of the comment itself, and a
