Enterprise Architecture (EA) is a strategic approach designed to align business strategy with ICT initiatives which has become part of the digital government transformation programme in most countries. The Malaysian Public Sector (MPS) has embraced EA as one of the pillars in their digital transformation initiative. However, findings from Malaysian Administrative Modernisation and Management Planning Unit (MAMPU) in 2016 revealed that EA establishment in MPS is still at its infancy level due to the lack of EA readiness. Similarly, public sectors in other countries such as Indonesia, Vietnam and Oman are also struggling to resolve this issue. Until June 2020, only six (6) agencies in MPS have established EA compared to 25 agencies targeted by MAMPU. Thus, to address this issue, this research proposes an EA Readiness Assessment Model (EARAM) with the aim to assess readiness of MPS, support decision-making process, and plan strategies for EA establishment. This research has four (4) objectives. The first objective is the identification of EA readiness factors followed by the second objective which is the development of EARAM. The third objective is to validate the developed EARAM, while the fourth objective involved evaluation of EARAM. A sequential exploratory mixed method research design was employed to achieve these four (4) objectives. To achieve the first and second objectives, this research used a systematic review (SR) and interview with five (5) EA experts; while the third objective involved three rounds of modified Delphi technique with 13 EA experts. Finally, for the fourth objective, the researcher adopted a multiple case study method whereby three (3) agencies in MPS that are in the EA establishment stage were selected. The EARAM was formulated based on several inputs from SR, interview findings, as well as Information Technology and Information System (IT/IS) Readiness Maturity model. The overall results of three (3) cycles of Delphi technique yielded the conclusion that 45 statements of elements, factors and items in the questionnaires received high consensus of importance in which their Inter Quartile Range (IQR) is between zero (0), and one (1) and median is more than four (4). Results from the Delphi analysis validated four (4) major elements of EARAM, namely 1) Catalyst Enabler, 2) People, 3) Process and 4) Technology along with 14 factors and 45 items. The EA Readiness Assessment Tool (EARAT) is developed by incorporating EARAM validated elements and factors to provide practitioners with an automated tool to assess the EA readiness level of their organisation. The results of EARAT’s evaluation from three (3) agencies in MPS indicated a high level of agreement (with a median score of more than 4.00) that EARAT provides useful and quality information, supports decision making, as well as provides ease of use and user satisfaction to support EA establishment in MPS. In conclusion, this research contributed to the development of EARAM to assess readiness in MPS, supports decision-making process, and plan strategies for EA establishment. This research is also in line with EA Body of Knowledge (EABOK) related to the areas of Organisational Scope and Structure of EA, specifically focusing on the sub-areas of Organisational Need and Drivers
