Well it really depends, some airlines/airports has more than three hub peak waves in any 12 hour window. OR Tambo airport has busy mornings and busy evenings with slightly moderate mid-mornings to early afternoon, therefore making it difficult to fully optimize resources evenly spread throughout the day, hence this type of deficiencies. BUT, the fundamental issue is more structural, to fix it, the executive level and the level below them must be dissolved and reconfigured with rationalized structure (with good business acumen) then the chances of winning will be high.
