STATIC PLAN • Team changes • Requirements change • Low quality increases development time • What can we do? Amir Barylko - Agile Planning MavenThought Inc.
AGILE PLAN • Know your backlog of stories • Use iterations (one to two weeks) • Estimate velocity (how many points per iteration) • Update estimations Amir Barylko - Agile Planning MavenThought Inc.
