How do we calculate total time and free float time? In critical path analysis.

3 weeks ago
Hero:

easy. Will only explain when you're online @Karla

3 weeks ago
Karla:

I'm online right now Are you?

3 weeks ago
Karla:

@Hero

3 weeks ago
Hero:

Sorry I missed you @Karla

3 weeks ago
Karla:

Now?

3 weeks ago
Hero:

Oh there you are. Is it possible for you to upload the question you're working on. Can you screenshot it from your textbook and upload it here?

3 weeks ago
Karla:

There is no option to upload the picture

3 weeks ago
Hero:

Oh but there is. It's called "Attach File". It is a set of buttons right below the typing box.

3 weeks ago
Karla:

I'm using mobile

3 weeks ago
Hero:

Oh. Well use a website like postimage.org to upload it.

3 weeks ago
Hero:

Then post the link here. That's what 99% of users usually do.

3 weeks ago
Hero:

Keep in mind I have a limited amount of time.

3 weeks ago
Karla:

Oh I've uploaded

3 weeks ago
Hero:

You have to post the link to the image here. I'm sorry you've never done this before. i don't know how to show you how to do this correctly.

3 weeks ago
Karla:

Yea I haven't

3 weeks ago
Hero:

c'mon Karla. You can figure this out. It's not a difficult site to use.

3 weeks ago
Karla:

I figured that out 😃

3 weeks ago
Hero:

nah you posted the wrong link.

3 weeks ago
Karla:

Oh

3 weeks ago
Hero:

You posted a link to the gallery not the link to the image.

3 weeks ago
Karla:

Oh I did that

3 weeks ago
Karla:

It's part 4 Calculate all free float and total floats

3 weeks ago
Hero:

Trust me, you still have not done it right. The link you posted is still the incorrect link even though QC processed it as an image. Whatever you posted kicked me off QC and I had to sign in again. Nevertheless, I have the image now.

3 weeks ago
Karla:

Oh I can see the picture without link here

3 weeks ago
Hero:

Yes Karla, as I said "QC processed it as an image". But trust me, you still have not posted the correct link. I don't know why you haven't figured it out yet, but it doesn't matter I have the image. Anyway what I want to say is that your book is using terminology I have never heard of before.

3 weeks ago
Hero:

It's non-traditional terminology. What is the name of this textbook?

3 weeks ago
Karla:

Peter stimpson and Alastair farquharson Cambridge international As and A level Business Coursebook third edition

3 weeks ago
Hero:

That explains it. It's international. I'll never be able to find it now.

3 weeks ago
Karla:

Oh

3 weeks ago
Hero:

It's okay, I'll try to do some research on these terms.

3 weeks ago
Karla:

Oh okay thank you!

3 weeks ago
Karla:

What terms I can tell you them

3 weeks ago
Hero:

I'm starting to figure it out. Hang on.

3 weeks ago
Karla:

Ok

3 weeks ago
Hero:

Let me ask, have you already created your network diagram?

3 weeks ago
Hero:

@Karla are you still here?

3 weeks ago
Karla:

Yea

3 weeks ago
Hero:

Okay, just checking.

3 weeks ago
Karla:

I tried to make one but I'm not sure that is correct

3 weeks ago
Hero:

Okay, how much time to do you have to work on this question. I have to start getting ready for work.

3 weeks ago
Karla:

5 min maybe What is the time in your country

3 weeks ago
Karla:

You can tell me the time when you are free I'll get online

3 weeks ago
Karla:

It is 8.44 pm here

3 weeks ago
Hero:

Okay. Basically, I won't be back for a couple hours. I should be back by 11:30 pm your time.

3 weeks ago
Hero:

And hopefully I'll have solved everything by then

3 weeks ago
Karla:

Alright Thank you! I'll get online

3 weeks ago
Hero:

Then I can explain it

3 weeks ago
Karla:

Ok

3 weeks ago
Hero:

See you in a couple hours

3 weeks ago
Karla:

Okay

3 weeks ago
Hero:

So if I ping you @Karla will you get an alert?

3 weeks ago
Karla:

No when I'll get online then I can see that

3 weeks ago
Karla:

Only

3 weeks ago
Hero:

You should either set up a gmail on QC then set it up to receive alerts.

3 weeks ago
Karla:

Oh I dont use gmail to often

3 weeks ago
Karla:

too*

3 weeks ago
Hero:

whatever email you use, you should add it to QC

3 weeks ago
Karla:

Ok

3 weeks ago
Hero:

Your email service should have a way for you to set up alerts

3 weeks ago
Hero:

Anyway, I have to go

3 weeks ago
Karla:

Okay Bye

3 weeks ago
Karla:

Hey!

3 weeks ago
Karla:

I'm back

3 weeks ago
Karla:

I am unable to make draw last part

3 weeks ago
Hero:

Hi

3 weeks ago
Hero:

I'm back as well. Let me put together a solution for this

3 weeks ago
Karla:

Hi! Ok

3 weeks ago
Karla:

You there?

3 weeks ago
Hero:

Yes sorry. I'm done

3 weeks ago
Hero:

I haven't done this in like 8 years so I had to re-familiarize myself

3 weeks ago
Karla:

Oh

3 weeks ago
Hero:

But I have the solution

3 weeks ago
Karla:

Great!

3 weeks ago
Hero:

3 weeks ago
Hero:

Let me know if you have any questions

3 weeks ago
Karla:

F must be completed before I commence

3 weeks ago
Karla:

So as F has no preceding activity shouldn't it be connected with first node

3 weeks ago
Hero:

Yes that is correct. It isn't connected to anything except I

3 weeks ago
Hero:

Do you see that this is the case?

3 weeks ago
Karla:

But If i remember that correctly when anything has no preceding activity it is connected with first mode?

3 weeks ago
Hero:

I only grouped it beneath A since both A and I have no preceding activity

3 weeks ago
Karla:

Node*

3 weeks ago
Hero:

But they are NOT connected

3 weeks ago
Hero:

Do you understand that F is only connected to I?

3 weeks ago
Karla:

Yea

3 weeks ago
Hero:

Okay great

3 weeks ago
Karla:

Ok

3 weeks ago
Hero:

Is that really the only question you have?

3 weeks ago
Karla:

Yea But I've another question in which I only need to calculate free float and total float So after this I'll do that myself

3 weeks ago
Hero:

Well, I think that now that you have the correct answer you should be able to calculate those things.

3 weeks ago
Hero:

I can help if necessary

3 weeks ago
Karla:

Oh Total float is LFT-duration-EST And FREE FLOAT= EST(next activity)-duration -EST (this activity) I dont get that what LFT or EST will we take? I mean of A,B,C,D...?

3 weeks ago
Hero:

And what does LFT and EST stand for. Your nation deals with completely different terminology so you can't use any acronyms with me.

3 weeks ago
Karla:

oh sorry EST=earliest start time LFT=latest finish time

3 weeks ago
Hero:

Yeah I don't get your notation either.

3 weeks ago
Hero:

are those dashes supposed to be subtraction symbols?

3 weeks ago
Karla:

Yep

3 weeks ago
Hero:

rewrite the formulas and put MINUS instead of dash

3 weeks ago
Karla:

Okay

3 weeks ago
Hero:

You can use acronyms now that I know what they mean

3 weeks ago
Karla:

Total float is Latest Finish Time(minus) duration( minus) earliest start time And FREE FLOAT= Earliest start time(next activity) (minus) duration (minus) earliest start time(this activity)

3 weeks ago
Karla:

Oh

3 weeks ago
Karla:

Okay

3 weeks ago
Hero:

Hmmm interesting.

3 weeks ago
Hero:

they want this for each node (A, B, C, D)?

3 weeks ago
Hero:

or for the entire project time

3 weeks ago
Hero:

@Karla

3 weeks ago
Hero:

Do they want these calculations for each node?

3 weeks ago
Karla:

Oh each node okay Then I'll do that

3 weeks ago
Hero:

No, I'm asking if that's what they want

3 weeks ago
Hero:

I don't know if that's what they want.

3 weeks ago
Karla:

Oh now I reread the question it says all free float

3 weeks ago
Karla:

Thank you so much!

3 weeks ago
Hero:

I'm lost lol

3 weeks ago
Hero:

But it says to calculate these values only for the non-critical nodes

3 weeks ago
Karla:

Oh yea So I'll find the non critical path and put the values in formula

3 weeks ago
Karla:

Right?

3 weeks ago
Hero:

Correct

3 weeks ago
Hero:

But actually you don't have to find a non-critical path

3 weeks ago
Karla:

Why?

3 weeks ago
Hero:

Just find the non-critical nodes

3 weeks ago
Karla:

Oh yea 👌

3 weeks ago
Karla:

Ok

3 weeks ago
Karla:

Thank you so much!

3 weeks ago
Hero:

Looks like the non-critical nodes are CDF and H

3 weeks ago
Hero:

How do you intend to calculate the Free and Total Float for node C for example?

3 weeks ago
Hero:

Show me your work for that

3 weeks ago
Karla:

Ok 1 min

3 weeks ago
Karla:

So total float is 4-2-4 Right?

3 weeks ago
Hero:

Where are you getting those numbers from?

3 weeks ago
Karla:

From your diagram

3 weeks ago
Hero:

I don't see 4 listed twice for node C

3 weeks ago
Hero:

Also, if you're getting them from my diagram, how do you know how to interpret those numbers?

3 weeks ago
Karla:

But what we make have 2 earliest start time and latest finish time

3 weeks ago
Karla:

But when we make we have 2 numbers *

3 weeks ago
Hero:

I never used any such numbers to represent "early start time" and "latest finish time"

3 weeks ago
Karla:

Oh so what u do?

3 weeks ago
Hero:

I only used two sets of numbers. Duration of Time To Complete a Particular Node By Itself and Total Project Time It Takes To Complete Node X Starting from Node A

3 weeks ago
Hero:

Something like that

3 weeks ago
Karla:

Oh

3 weeks ago
Hero:

X represents any node other than node A

3 weeks ago
Hero:

and F

3 weeks ago
Karla:

Oh we do like I send you the pic

3 weeks ago
Karla:

That is different way

3 weeks ago
Hero:

Yeah, I calculated it correctly.

3 weeks ago
Hero:

I know you do it differently but the answer is still correct

3 weeks ago
Karla:

Oh

3 weeks ago
Karla:

Ok

3 weeks ago
Hero:

Some of the calculations are unnecessary from my point of view.

3 weeks ago
Karla:

Ok

3 weeks ago
Hero:

But let me help you out

3 weeks ago
Karla:

Ok

3 weeks ago
Hero:

C and D each have two extra days of float time since it will take B 6 days to complete F has 6 days of float time H has only 1 day of float time 2 + 2 + 6 + 1 = 11 total float time

3 weeks ago
Hero:

11 total float days*

3 weeks ago
Hero:

Does that make any sense to you at all?

3 weeks ago
Karla:

You got H as 1 As G=12 And H=11 So difference

3 weeks ago
Hero:

Yes, I think you are interpreting correctly the way I am calculating Free Float and Total Float

3 weeks ago
Karla:

Oh alright

3 weeks ago
Hero:

Free Float C = 2 days of free float D = 2 days of free float F = 6 days of free float H = 1 day of free float Total Float 2 + 2 + 6 + 1 = 11 days total float

3 weeks ago
Karla:

Alright

3 weeks ago
Hero:

If I have to do it the teacher way, I usually run

3 weeks ago
Hero:

I rather do it the easy way

3 weeks ago
Karla:

Yea that was really easy way

3 weeks ago
Karla:

Thank you so much!!

3 weeks ago
Hero:

But it is important to manage the time properly because it is easy for the manager to think "Oh we have 11 days to play around with". That's plenty of time. Then if the employees think they have 11 days of float time, they won't do anything for 11 days and the project will surely fail. So don't tell the employees and monitor the time very closely.

3 weeks ago
Hero:

I think that actually answers one of the questions as well.

3 weeks ago
Hero:

Maybe you can think of a more technical way of explaining why the time must be monitored closely.

3 weeks ago
Hero:

Oh, you already did #3, nevermind

3 weeks ago
Karla:

No I didn't lol But I've to write advantages of critical path analysis so that are written in book

3 weeks ago
Karla:

And disadvantages

3 weeks ago
Karla:

With some additional detail

3 weeks ago
Hero:

If any delays occur, then you can push back the start time for the non-critical projects and delicate manpower towards ensuring the critical projects are completed on time.

3 weeks ago
Hero:

Also, post the feedback from your instructor regarding this particular question.

3 weeks ago
Karla:

Okay

3 weeks ago
Karla:

Thanks!

3 weeks ago
Hero:

You bet

3 weeks ago
Karla:

Yea
