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

2 months ago
Hero:

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

2 months ago
Karla:

I'm online right now Are you?

2 months ago
Karla:

@Hero

2 months ago
Hero:

Sorry I missed you @Karla

2 months ago
Karla:

Now?

2 months 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?

2 months ago
Karla:

There is no option to upload the picture

2 months ago
Hero:

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

2 months ago
Karla:

I'm using mobile

2 months ago
Hero:

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

2 months ago
Hero:

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

2 months ago
Hero:

Keep in mind I have a limited amount of time.

2 months ago
Karla:

Oh I've uploaded

2 months 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.

2 months ago
Karla:

Yea I haven't

2 months ago
Hero:

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

2 months ago
Karla:

I figured that out 😃

2 months ago
Hero:

nah you posted the wrong link.

2 months ago
Karla:

Oh

2 months ago
Hero:

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

2 months ago
Karla:

Oh I did that

2 months ago
Karla:

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

2 months 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.

2 months ago
Karla:

Oh I can see the picture without link here

2 months 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.

2 months ago
Hero:

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

2 months ago
Karla:

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

2 months ago
Hero:

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

2 months ago
Karla:

Oh

2 months ago
Hero:

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

2 months ago
Karla:

Oh okay thank you!

2 months ago
Karla:

What terms I can tell you them

2 months ago
Hero:

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

2 months ago
Karla:

Ok

2 months ago
Hero:

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

2 months ago
Hero:

@Karla are you still here?

2 months ago
Karla:

Yea

2 months ago
Hero:

Okay, just checking.

2 months ago
Karla:

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

2 months ago
Hero:

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

2 months ago
Karla:

5 min maybe What is the time in your country

2 months ago
Karla:

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

2 months ago
Karla:

It is 8.44 pm here

2 months ago
Hero:

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

2 months ago
Hero:

And hopefully I'll have solved everything by then

2 months ago
Karla:

Alright Thank you! I'll get online

2 months ago
Hero:

Then I can explain it

2 months ago
Karla:

Ok

2 months ago
Hero:

See you in a couple hours

2 months ago
Karla:

Okay

2 months ago
Hero:

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

2 months ago
Karla:

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

2 months ago
Karla:

Only

2 months ago
Hero:

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

2 months ago
Karla:

Oh I dont use gmail to often

2 months ago
Karla:

too*

2 months ago
Hero:

whatever email you use, you should add it to QC

2 months ago
Karla:

Ok

2 months ago
Hero:

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

2 months ago
Hero:

Anyway, I have to go

2 months ago
Karla:

Okay Bye

2 months ago
Karla:

Hey!

2 months ago
Karla:

I'm back

2 months ago
Karla:

I am unable to make draw last part

2 months ago
Hero:

Hi

2 months ago
Hero:

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

2 months ago
Karla:

Hi! Ok

2 months ago
Karla:

You there?

2 months ago
Hero:

Yes sorry. I'm done

2 months ago
Hero:

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

2 months ago
Karla:

Oh

2 months ago
Hero:

But I have the solution

2 months ago
Karla:

Great!

2 months ago
Hero:

2 months ago
Hero:

Let me know if you have any questions

2 months ago
Karla:

F must be completed before I commence

2 months ago
Karla:

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

2 months ago
Hero:

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

2 months ago
Hero:

Do you see that this is the case?

2 months ago
Karla:

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

2 months ago
Hero:

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

2 months ago
Karla:

Node*

2 months ago
Hero:

But they are NOT connected

2 months ago
Hero:

Do you understand that F is only connected to I?

2 months ago
Karla:

Yea

2 months ago
Hero:

Okay great

2 months ago
Karla:

Ok

2 months ago
Hero:

Is that really the only question you have?

2 months 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

2 months ago
Hero:

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

2 months ago
Hero:

I can help if necessary

2 months 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...?

2 months 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.

2 months ago
Karla:

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

2 months ago
Hero:

Yeah I don't get your notation either.

2 months ago
Hero:

are those dashes supposed to be subtraction symbols?

2 months ago
Karla:

Yep

2 months ago
Hero:

rewrite the formulas and put MINUS instead of dash

2 months ago
Karla:

Okay

2 months ago
Hero:

You can use acronyms now that I know what they mean

2 months 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)

2 months ago
Karla:

Oh

2 months ago
Karla:

Okay

2 months ago
Hero:

Hmmm interesting.

2 months ago
Hero:

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

2 months ago
Hero:

or for the entire project time

2 months ago
Hero:

@Karla

2 months ago
Hero:

Do they want these calculations for each node?

2 months ago
Karla:

Oh each node okay Then I'll do that

2 months ago
Hero:

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

2 months ago
Hero:

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

2 months ago
Karla:

Oh now I reread the question it says all free float

2 months ago
Karla:

Thank you so much!

2 months ago
Hero:

I'm lost lol

2 months ago
Hero:

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

2 months ago
Karla:

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

2 months ago
Karla:

Right?

2 months ago
Hero:

Correct

2 months ago
Hero:

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

2 months ago
Karla:

Why?

2 months ago
Hero:

Just find the non-critical nodes

2 months ago
Karla:

Oh yea 👌

2 months ago
Karla:

Ok

2 months ago
Karla:

Thank you so much!

2 months ago
Hero:

Looks like the non-critical nodes are CDF and H

2 months ago
Hero:

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

2 months ago
Hero:

Show me your work for that

2 months ago
Karla:

Ok 1 min

2 months ago
Karla:

So total float is 4-2-4 Right?

2 months ago
Hero:

Where are you getting those numbers from?

2 months ago
Karla:

From your diagram

2 months ago
Hero:

I don't see 4 listed twice for node C

2 months ago
Hero:

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

2 months ago
Karla:

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

2 months ago
Karla:

But when we make we have 2 numbers *

2 months ago
Hero:

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

2 months ago
Karla:

Oh so what u do?

2 months 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

2 months ago
Hero:

Something like that

2 months ago
Karla:

Oh

2 months ago
Hero:

X represents any node other than node A

2 months ago
Hero:

and F

2 months ago
Karla:

Oh we do like I send you the pic

2 months ago
Karla:

That is different way

2 months ago
Hero:

Yeah, I calculated it correctly.

2 months ago
Hero:

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

2 months ago
Karla:

Oh

2 months ago
Karla:

Ok

2 months ago
Hero:

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

2 months ago
Karla:

Ok

2 months ago
Hero:

But let me help you out

2 months ago
Karla:

Ok

2 months 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

2 months ago
Hero:

11 total float days*

2 months ago
Hero:

Does that make any sense to you at all?

2 months ago
Karla:

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

2 months ago
Hero:

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

2 months ago
Karla:

Oh alright

2 months 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

2 months ago
Karla:

Alright

2 months ago
Hero:

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

2 months ago
Hero:

I rather do it the easy way

2 months ago
Karla:

Yea that was really easy way

2 months ago
Karla:

Thank you so much!!

2 months 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.

2 months ago
Hero:

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

2 months ago
Hero:

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

2 months ago
Hero:

Oh, you already did #3, nevermind

2 months ago
Karla:

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

2 months ago
Karla:

And disadvantages

2 months ago
Karla:

With some additional detail

2 months 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.

2 months ago
Hero:

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

2 months ago
Karla:

Okay

2 months ago
Karla:

Thanks!

2 months ago
Hero:

You bet

2 months ago
Karla:

Yea
