studies pointed out this fact. Due to the the ever
changing business and customer demands, projects
with short time frame (Challenge 2) are also a typ-
ical characteristic of SMEs, especially for the ones
that focus on the evolution of software products of a
given domain (Silva and Carneiro, 2016).
The third issue highlighted by the selected stud-
ies is small teams with work overload - (Challenge
3) (Silva and Carneiro, 2016). This issue was cited
by nine papers (M01-M03, M08, M12, M14, M15,
M20 and M31), corresponding to 25% of the selected
studies. Small teams in SMEs should be taken into
account when planning the software process improve-
ment. In this case, participants of the teams can take
different roles depending on the demand. There are
roles such as quality auditor that can not be assumed
by the team members due to conflict of interest. In
this case, an external professional can provide an on-
demand service for this purpose.
Low focus on process - (Challenge 4) is an ev-
idence provided by eight papers (M01, M03, M08,
M12, M14, M15, M19 and M36), corresponding to
22% of the selected papers. It reveals how SMEs
deal with daily development practices. This means
that organizations can be subjected to conduct soft-
ware projects in a non-coordinated way and the teams
involved in the software projects are not always con-
cerned with software process improvement (Silva and
Carneiro, 2016). Limited number of customers -
(Challenge 5) is another issue pointed out by seven
(M01, M03, M06, M07, M12, M15 and M22) (19%)
of the selected studies. These type of companies need
to maintain the relationship with their clients, other-
wise the company can suffer the consequences of the
competitors.
Agility to deal with requirements volatility -
(Challenge 6) was an issue identified in six papers
(M01, M03, M07, M15, M18 and M34) correspond-
ing to 17% of the selected studies. Even after vali-
dating the requirements with the client, change in re-
quirements are inevitable. Responding to these de-
mands is crucial to keep clients satisfied. Absence of
training focusing on process - (Challenge 7) was also
identified in six papers (M03, M08, M12, M14, M19
and M35) corresponding to 17% of the selected stud-
ies.
Protection of intellectual property - (Challenge 8)
also corresponds to 17% of the selected studies (M06,
M24, M25, M30, M33 and M35) and has the poten-
tiality to encourage companies and their teams to in-
novate in new products, new techniques or approaches
that can lead to market differential. The next issues
are difficulty to include best practices- (Challenge 9),
mentioned in five studies (M01, M12, M14, M19 and
M36) and high cost of SPI qualified professionals -
Challenge 10 - reported in studies M02, M05, M11,
M13 and M34 (Silva and Carneiro, 2016). The results
of this SLR were used as reference for the field study
presented in the next section.
4 FIELD STUDY IN SMALL AND
MEDIUM ENTERPRISES
This sections presents the results of a field study
to characterize the perception of Small and Medium
Enterprises (SMEs) from Feira de Santana city of
State of Bahia in Brazil. The reason for having cho-
sen this city was the perceived number of organiza-
tions willing to implement software process improve-
ment practices, despite not having any company of-
ficially adopted a well-known software process refer-
ence model such as CMMI (Chrissis et al., 2011) or
MPS.BR (Montoni et al., 2009). This was considered
an appropriate scenario to perform the field study, to
collect and analyze data as well as to compare them
with the findings obtained in the Systematic Litera-
ture Review already conducted by the authors (Silva
and Carneiro, 2016) and briefly presented in the pre-
vious section.
4.1 Planning and Execution
We contacted 30 companies from Feira de Santana
city. Eleven companies agreed to take part in the
study. We conducted semi-structured face-to-face in-
terviews with representatives of these companies to
collect data for the characterization study. We consid-
ered the forms published in (Sulayman et al., 2012)
to be adjusted and used in this study
3
. According to
the confidentially agreement, the identification of the
companies were preserved. The goal of the first form
was to collect data related to the interviewed profile
representing each company. The second form col-
lected data related to the company. The third form
had the goal to evaluate to which extent the company
was aligned to the seven items proposed by (Dyb
˚
a,
2003) and listed as follows: a) Business orientation:
the extent to which SPI goals and actions are aligned
with explicit and implicit business goals and strate-
gies; b) Involved leadership: the extent to which lead-
ers at all levels in the organization are genuinely com-
mitted to and actively participate in SPI; c) Employee
participation: the extent to which employees use their
