A well-known saying is that time is money. Is it true?
Tal Levanon, the developer of the HCP method and the HCP-Go SaaS for analyzing project schedules, examines this question and its implications in building a project schedule.
I would like to ask a question: Does time equal to money?
A well-known saying is that: Time is money.
It feels like the statement is true –
After all, we all have the ability to make money over time …
Is it true?
If that was a real equation in math, we could also say that: Money equals time. But, when you say that, you know it’s not true. After all, we can’t produce more time for ourselves – even if we have a lot of money …
So, what is the main difference between time and money?
On the financial axis – one can move back and forth:
- One can be in debt
- One can have all the money needed
- One can take a loan
- One can give a loan to someone else
On the time axis – one can only move forward: From this moment – to the next moment. You can’t go back in time, except in books or movies – which is why they are so fascinating (to me, at least)
So, when it comes to writing a schedule – You can think from the end to the beginning – that is flexible thinking and it’s great !!
But,
- You shouldn’t link tasks from the future to the past.
- It’s highly recommended not to use a start-to-finish (SF) link – which “thinks” from the future to the past.
- It’s highly advised not to use a negative delay – which goes back in time.
When one writes a schedule – It can only be in one direction:
From the present to the future or from the future to a distant future.
Always look forward …
