Senior bankers can’t meet deadlines

Working in a BB industry group and realizing that we very rarely meet client / internal deadlines with most of our deliverables. With the exception of inflexible bid due dates, if it’s up to our seniors we will always push things back by weeks if not months. Anyone else having the same experience?

My theory is that working with constant arbitrary/impossible internal deadlines eventually makes you realize all timelines are fungible. But I wonder what the client would think if they knew we pushed our model call back bc the MD refused to provide sign off until 3 days after the call was scheduled (with materials already finalized).

Interested to hear others’ thoughts / experiences.
