businesses. Among them, SMEs play a central role in 
this shift,  representing about 90%  of  the world  and 
providing more than 50% of jobs. In OECD
 countries, 
SMEs account for 75  percent of jobs  in  the sectors 
most severely  affected by  the epidemic, and micro-
enterprises with fewer than 10 employees account for 
about  30  percent  of  jobs  in  those  industries.  In 
emerging economies, formal SMEs account for 40% 
of  GDP,  creating  7  of  the  10  jobs  (OECD,  2021). 
Therefore,  SMEs  using  digital  technologies  to 
innovate  the  production  modes  and  management 
concepts, and promote  sustainable development  are 
the key to unleashing the global economic potential. 
In fact, there is few research on digital technologies 
for SMEs, and the digitalization of many companies 
is still in the initial stage, and most companies know 
little  about  digital  technologies  and  have  no  clue 
about  how  to  implement  digital  technologies  to 
survive.  It  motivates  the  study  of  this  paper  to 
propose  the  maturity  assessment  reference 
framework  to  assist  companies  to  embark  on  the 
digitalization journey. 
The paper is organized as follows. Section II will 
conduct the literature review. Section III will propose 
the  maturity  assessment  reference  framework. 
Section  IV  will  conduct  the  case  studies  for  two 
companies  by  applying  the  proposed  maturity 
assessment  reference  framework.  Section  V  will 
conclude the paper with remarks. 
2  LITERATURE REVIEW 
This  section  reviews  the  literature  on  digital 
technologies  and  digital  transformation  maturity 
assessment models, and identifies the research gaps 
in the literature, which motivate the research works in 
this paper. 
The  essence  of  digital  transformation  is  that 
organizations  use  the  corresponding  digital 
technologies  to  respond  to  changes,  which  is  the 
source  of  disruption.  In  this  process,  digital 
technologies  play  a  central  role  in  the  creation  and 
reinforcement of disruption that occurs in the society 
and  industry.  Digital  technologies  create  the  drive 
that drives organizations to implement responses to 
gain  or  maintain  their  competitive  advantages.  Vial 
classified 282 digital transformation documents and 
found  that  most  digital  technologies  are  related  to 
social,  analysis,  mobile,  Internet  of  Things,  cloud 
(Vial, 2019), consistent with Zhu et al. on 865 digital 
transformation  documents  from  2000  to  2020  and 
moreover, digital platforms are an important category 
(Zhu,  Ge,  Wang,  2021).  The  business  competition 
increasingly  relies  on  the  ability  to  use  digital 
technologies.  In  defining  digital  technologies,  Vial 
observed  that  combinations  of  technologies  are 
particularly  relevant  in  the  context  of  digital 
transformation. For example, the ability to implement 
algorithmic  decisions  may  depend  on  the  ability  of 
companies  to  analyze  big  data  collected  by 
individuals using social media through their mobile 
phones. In the study of Zhu et al. on the thriving stage 
from  2018  to  2020  of  the  digital  transformation 
literature,  the  research  on  digital  technologies 
compared  to  digital  business  strategy,  digital 
transformation  of  manufacturing  (Industry  4.0), 
digital enterprise architecture and other fields is the 
least (Vial, 2019). 
The  findings by  DeStefano  et  al.  suggested that 
younger companies using cloud computing are more 
likely  to  increase  jobs  and  sales,  and  that  cloud 
computing  and  fiber-optic  infrastructure  enable 
younger  companies  to  scale  up  without  increasing 
their  geographic  footprint.  In  addition,  cloud 
computing  improves  employee  mobility  between 
institutions  within  the  enterprise.  Cloud  technology 
reduces  fixed  IT  costs  for  enterprises,  and  can 
technically replace their own IT devices, facilitating 
start-ups  to  grow  (DeStefano,  Kneller  &  Timmis 
2020). From the perspective of the strategic choice of 
Russian  enterprises,  Lezina  et  al.  diagnosed  the 
digital  maturity  preparation  model  of  system 
management,  company  structure,  business  process, 
data management and personnel preparation through 
the form of questionnaires. The model created by the 
authors  is  universal  and  targeted  at  all  kinds  of 
enterprises (Lezina, et al, 2019). Yezhebay et al. used 
the  SWOT  analysis  method  to  define  the 
characteristics  of  advantages  and  disadvantages  for 
SMEs  in  Kazakhstan,  and  developed  the  digital 
maturity model for SMEs in Kazakhstan. The model 
consists  of  six  dimensions  that  are  strategy, 
leadership,  personnel,  product,  operations  and 
technology,  and  the  corresponding  15  sub-
dimensions (Yezhebay, et al, 2021).   
In  the  literature,  the  maturity  models  for  SME 
digitalization  are  mostly  based  on  the  Industry  4.0 
model. The most maturity models did not consider the 
specific  requirements  and  challenges  of  SMEs  and 
cannot reflect the actual status of digital technologies 
in  SMEs  (Mittal,  et al,  2018).  As  such,  SMEs  are 
unable  to use  those  maturity models to  assess  their 
digital  technology  level.  Thus,  it  is  significant  to 
create an appropriate maturity assessment framework 
for  SMEs  to  assess  their  maturity  level  for 
implementing  digital  technologies  and  make a right
