Purpose
This paper aims to investigate the factor analysis for balanced scorecard (BSC) as measuring competitive advantage of infrastructure assets of owned state ports in Indonesia: Pelindo IV, Makassar, Indonesia.

Design/methodology/approach
This investigation adopts an explanatory and an exploratory qualitative case study method to analyze the effectiveness of BSC over the strategy management processes. For data collection, the researchers have used semi-structured interviews, direct observation and document collection. Data collection was made during a six-month period, which allowed gaining of deep knowledge on the culture and management methods used in alpha. Other data collected refer to the company’s documentation and reporting of online media publications. Detailed interview data are the main data sources, which allow obtaining of a detailed and holistic understanding of the experience, opinions and attitudes of the interviewees. Interviews focus on asset management to determine the relationship between various factors. This study adopts ideal BSC principle (four perspectives) to develop strategic map for infrastructure asset of Pelindo IV. Analysis tools using factor analysis for the indicators (financial, customer, learning-growth and internal process) measure the competitive advantages. The data for factor analysis from the perception of each stakeholder using questionnaire are collected.

Findings
The competitive advantages of Pelindo IV depend on 81.2 per cent from financial perspective, customer perspective, internal process perspective and learning perspective, and 18.2 per cent from the other factor. The result of measurement model of competitive advantage in Figure 2 is significantly (p-value < 0.05) measured by financial perspective performance, customer perspective performance, internal process perspective performance and learning perspective performance. On the basis of the highest coefficient loading factor, it can be shown that the most powerful competitive advantages are measured by learning perspective. The high value of competitive advantage of Pelindo IV, Makassar, Indonesia, is especially seen from the learning perspective performance. The order result of BSC for measuring the competitive advantages is as follows: learning perspective performance, financial perspective performance, customer perspective performance and internal process perspective performance.

Originality/value
Originality of this study looks at the following three points: first, the measurement competitive advantages. Previous studies used measurements of cost leadership strategy, differential strategy and focus strategy as competitive advantages measuring (Porter, 1985; Warf and Stutz, 2007; Clulow et al., 2003). This study uses BSCs with four indicators (financial perspective result, customer perspective result, internal process perspective result and learning perspective). Second, on the other hand, several studies have investigated the BSCs as performance measurement (Ozturk and Coskun, 2014; Malgwi and Dahiru, 2014; Binden et al., 2014). Third, this study uses the factor analysis to measure the competitive advantage by BSCs, which is different from the previous study analysis.
