Explanation

14.

The deadlines are set with the help of an agile methodology called Scrum, a methodology used in the practice of software development.
The work provider decides on features that the programmer ought to create within a given week defined as a "sprint" in the methodology, the programmer signs the document and decides if he is satisfied that he would be able to complete the tasks within the given timeframe.
If he is late with his sprints and sees that he is not achieving them on time he has 2 weeks before the end of the fourth sprint to report that he won't be able to complete these sprints on time, if he won't be able to complete it on time due to goals unrealistically set the contract would be extended else if it is he doesn't reach these goals on time due to not performing with agreed skills and competencies he would have to complete the fourth sprint before receiving any payments.

15.
The programmer signed for the deadline thus he agrees that it is realistically set, if the deadlines is not reached due to facts coming to the programmers attention that he misjudged the speed that a task would take or other factors that weren't considered in discussion of the deadline this would constitute in the extension of the contract.
If the programmer is not reaching his deadlines due to underperforming he would only receive payments once deadlines are achieved. The programmer has two weeks to achieve his deadline after his deadline has surpassed, a meeting would be held after the first week to track his progress if after the second week he is not complete the contract would be canceled without paying due payments to the programmer.
Factors that weren't considered may include technical aspects of programming not provided for in the setting of the deadline, this may include...(speak to someone about this aspect)
Misjudgment of task speed can be defined as follows the programmer fully believed that he can perform a task a certain speed but even when performing at his full capacity can't achieve the given speed.
Underperformance not performing clearly set tasks fast enough
16.
In case the programmer absconds(defined as if the programmer doesn't reply in a week), dies, is unable to perform work, not performing all of his duties and has received 2 warnings, his contract will be canceled.
