The horizontal axis represents “Project Management Barriers”, labeled from left to right as “L F R”, “U C R”, “L C W A S”, “P S C”, “C S E”, and “C O B O”. The vertical axis represents “Project Management Barriers” and lists the same barriers arranged from top to bottom as “L F R”, “U C R”, “L C W A S”, “P S C”, “C S E”, and “C O B O”. The color scale on the right side shows correlation values ranging from 0.5 to 1.0, with lighter shades representing lower correlations and darker shades representing higher correlations. For L F R, the correlation values are: L F R (1.000), U C R (0.414), L C W A S (0.593), P S C (0.556), C S E (0.465), and C O B O (0.496). For U C R, the correlation values are: L F R (0.414), U C R (1.000), L C W A S (0.521), P S C (0.541), C S E (0.510), and C O B O (0.513). For L C W A S, the correlation values are: L F R (0.593), U C R (0.521), L C W A S (1.000), P S C (0.585), C S E (0.478), and C O B O (0.559). For P S C, the correlation values are: L F R (0.556), U C R (0.541), L C W A S (0.585), P S C (1.000), C S E (0.590), and C O B O (0.543). For C S E, the correlation values are: L F R (0.465), U C R (0.510), L C W A S (0.478), P S C (0.590), C S E (1.000), and C O B O (0.532). For C O B O, the correlation values are: L F R (0.496), U C R (0.513), L C W A S (0.559), P S C (0.543), C S E (0.532), and C O B O (1.000).Spearman's correlation heatmap of project management barriers
