class xerparser.dcma14.analysis.DCMA14(programme, duration_limit=1, lag_limit=0, tf_limit=0)

DCMA 14-point analysis for project schedule quality assessment.

This class performs a comprehensive analysis of a project schedule based on the Defense Contract Management Agency (DCMA) 14-point assessment criteria.

Parameters:

• programme – The project programme/schedule to analyze

• duration_limit (int) – Threshold for activity duration analysis (default: 1)

• lag_limit (int) – Threshold for relationship lag analysis (default: 0)

• tf_limit (int) – Threshold for total float analysis (default: 0)

Returns:

Analysis results in the following structure:

        "summary": {"activity_cnt": int, "relationship_cnt": int},
        "predecessors": {"cnt": int, "activities": list, "pct": float},
