PMP Success Story: Build Your PMI Muscles, Enhance Your PMIisms and be PMPed Before the Exam

Falguni Das is a proud PMP® today. He had his credential in the beginning of this month. Post certification he had messaged me on his success. Later, when I spoke with him at length, he was indeed very satisfied on the outcome. Well, sincere work rarely goes in vain. 

Falguni was part of my class in the end of January, 2016. It was a big batch and he made his presence felt by actively participating. 

He asks pertinent questions, answers and chips-in wherever he can, enjoys the tricky questions and actively joins in situations where I ask participants to discuss with the team at the whiteboard.


No two experiences are same. Like he had less number of mathematical questions compared to others. And, that is what makes this exam unique. Also he has put certain interesting perspectives on PMP exam – like building your PMI® muscles, being PMPed before exam and so on. 

His experience is quite detailed. Go on and read his unique experience.

Introduction

The inspiration to be a PMP came primarily due to the knowledge I wanted to gain in the Project Management space and of course the brand value of PMP certification. 

In the pursuit of having good quality training and the support from the staff during and after the training period, I took advice from few of my friends and colleagues about the centre and the coach. Additionally, I did go through the reviews about the same in the internet too.

My PMP Training Experience

My classroom experience was really good. I got to learn from an experienced coach and fellow associates there. The key takeaways in the PMP Training were:

• Deep understanding of certain knowledge areas such as Cost Management, Time Management, Risk Management and Procurement management. 
• The subtle yet very important differences between different types of project documents.

I have very good experience in few of the project management knowledge areas (as PMI calls them), but less in few others. Post my class, I kept working harder on the weak areas and tried to enhance my knowledge in my strong areas by reading the PMI related documents, discussing more with my colleagues and senior managers. It is easy to set one’s priority based on the PMI-defined percentage of questions each process group will pose. However, it is quite important to know a good deal of each knowledge area as that helps one during the exam and also while handling real project work.

My Own Study

First I blocked my exam dates. I would call it “Initiating”, and also here I fixed the closing date. I spent two months preparing, i.e., Planning and Executing, for the exam apart from the 4 days of classroom training that I attended. Every day I spent about two to three hours for my preparation. From beginning, I focussed on my weak areas, so that I got maximum time to prepare for those. 

As soon as I used to finish one knowledge area, I used to attempt few quiz questions (around 20-40 questions) on the same knowledge area, which can be considered partly executing, partly monitoring and controlling. However, do note, none of the questions that one practices may appear in the real exam. In my case too, I did not get those. Nevertheless, practising those will help you clear the concepts and gain more confidence.

I kept practicing different sets – 20 to 40, 50, 75, 100, 200 questions from time to time in order to build my PMI-muscles and enhance my PMI-ism. For my preparation, I referred the PMBOK® Guide and the book by Rita Mulcahy.

One particular aspect during my study which I would suggest is this: Look for avenues to implement what you learn during your preparation time and beyond by applying them in the real time projects.

In few questions, where one is not quite sure of the answers, it may bring the whole morale down in minutes. But I kept my calm, stayed focussed and remained alert in the common sense front. No matter how confident you are, till the result is out, no one knows the actual outcome. The key is to remain confident and calm – as you don’t have any better choice.

My PMP Exam Experience

I scheduled the exam online at a centre in Mumbai, India. My strategy for the exam was as follows:

• Plan was to answer all the questions in 210 mins and then review all the marked questions later. Though my planned time was 210 minutes, I finished answering all 200 questions in 225 mins, i.e., I had hardly 15 mins to go. As I had very few questions marked to be reviewed later, it saved the day for me.
• I tried to solve the questions in first attempt itself. This helped me in avoiding the review later, as noted earlier. 
• I read every question and answer choices thoroughly at least once. I was never too desperate to answer without reading completely, just because I thought one answer might be correct or the question seemed very easy.
• I kept an eye on the time, so that I did not have to overspend on one particular question.
• Finally, I stayed focussed, calm and confident throughout the 250+ mins.

There were a variety of questions. However,

• Mostly questions were situational – almost 90% of them
• Of those 90%, at least 25% questions were tricky (where the second best choice could not be that wrong or was equally good and possibly right)
• Mathematical questions – 2-3%

I must note what happened to me on the exam day, need not happen necessarily to everyone else in the exam. While speaking with several other examinees, I heard different distribution in percentages of these aforementioned types. One exam taker mentioned that he got around 20-25 mathematical questions, which translates to around 10-12%.

I would say - do not lose your patience, do not get distracted. Read, re-read the questions to get more clarity. In case it is too tough, mark the question to be reviewed later and move on. If you want to make certain notes, please do that. 

Suggestions for PMP Aspirants

- Dos:

• Read the PMBOK guide thoroughly. More importantly, try to understand the concepts (about the why, when and how). 
• Practice and attempt different types of questions, varieties of scenarios.  
• Define your own exam strategy, prepare your own notes. 
• Understand the importance of different documents and know when to use what sort of tools and techniques. 
• When you are unsure, use your common sense and experience. 
• Be “PMPed” before the exam! By PMPed I mean, understand what PMI says about project management. 

- Don’ts:

• Don’t procrastinate and push the exam date. 
• Never lose confidence in yourself.

Conclusion

In conclusion, I would implement the project management learning in real projects as much as possible as that was one of my primary goals. As a whole, the complete process has been a great experience and learning for me.

Practical PMP with MS Project - Negative Total Float

Can negative float exist in a schedule network? What impact does it have? How does it impacts the critical path? As a Project Planner or Manager how should work on these cases?

These were some of the questions that came up in a recent session on Practical PMP with MS Project. The MS Project® version used was 2016 and PMBOK® version used is its 5th edition.

First, the definition of Total Float (or Total Slack). Putting it simply:  "This is the amount of time that an activity can be delayed without delaying the project finish date or violating a schedule constraint."

Taking an example - say you have a task "Task - A". This task can be delayed by 3 days without delaying the project's finish date. The total float of Task - A is 3 days.

Now, let us take a MS Project sample, which is shown below. There are many tasks in this project - each of these tasks have Free Slack (or Free Float) or Total Slack (or Total Float) shown. To see these floats - just switch to View tab -- Data group -- Tables -- Schedule table (or you can add the columns in the default Entry table).

Figure - 1: A Sample Project

In the above project, let us look at Task B. It is starting on Wednesday (July 1) and finishing on Friday (July 3), i.e., a duration of 3 days. The project's end date is Wednesday, July 8 (in next week). Obviously, you can push "Task B" by 3 days - Monday, Tuesday and Wednesday (July 6, July 7 and July 8) - without impacting the finish date of the project. Hence the total float or total slack for Task B = 3 days. 

Note the critical path here: Start - Task E - Task F - Finish. It is the longest path or path having float values less than equal to zero. The critical path is highlighted in red. To see the critical path enable the checkbox "Critical Tasks" under Format tab -- Bar Styles group. There many other ways to see the critical tasks.

Next, let us see when the negative total float can come. 

Scenario - 1: Setting a Hard Constraint (MSO)

I'll be setting a hard constraint on Task B - a Must Start On (MSO) constraint. This can be done in the Task Information dialog box, which is launched when you double click on a task.

Figure - 2 : Hard Constraint Set

I have set the MSO on June 30 (Tuesday) for Task B, 1 day before the scheduled start of the task, which is July 1 (Wednesday). Next, I pressed the "OK" button in the dialog box. 

As I pressed OK, the below message popped up. I selected the 3rd option and continued by pressing OK button.

Figure - 3: Message while Setting the MSO

Next, the below message popped up. This is clearly saying there will be scheduling conflict if you set this constraint. 

Figure - 4: Message - Scheduling Conflict

We will go ahead as we know there will be scheduling conflict by setting a hard constraint on a linked task. I selected the 2nd option above and then clicked OK. 

Now, see the impact on the schedule. The new schedule comes as shown below with two critical paths now. But more importantly, the total float/slack of Task B is now changed from 3 days to -1 day.

Figure - 5: Total Float as Negative with MSO Constraint

The constraint is shown in the indicator column. As you can see B's total slack/float has turned negative. Similarly for the tasks it has been linked to. Also, another critical path has come in, i.e., Start - Task A - Task B - Finish. This is due to my setting for critical path - any tasks having a float value less than equal to zero will be critical.

By how it became -1 day (earlier 3 days)?

To understand that, let us draw the Schedule Network Diagram, where we will find out the Early Start (ES), Late Start (LS), Early Finish (EF) and Late Finish (LF). I am using Forward and Backward pass approach to calculate these values (as one would be doing while preparing for PMP Exam)

Figure - 6: Forward and Backward Pass Calculation

The legend on the top right of the above diagram shows the ES, LS, EF, LF values for each activity. 

Now total float is calculated as the difference between LS and ES or the difference between LF and EF. For example the total float for Task A = LS - ES = 4 - 1 = 3 days. Take the Task B, for it total float = LS - ES = 6 - 3 = 3 days. The result is same while being calculated with MS Project (refer Figure - 1). But that diagram does not show the ES, LS, EF, LF values. The below one shows (Figure - 7). To see Early Start, Late Start, Early Finish and Late Finish, you can add them as columns into the table of MS Project view.

Figure - 7: Forward and Backward Pass - Auto Calculated in MS Project

These values exactly matches what we saw in theory. For Task B, when it was scheduled, without any constraint:

ES = Wednesday (July 1) 
LS = Monday (July 6)
EF = Friday (July 3)
LF = Wednesday (July 8)
Total Slack = 3 days

Now, let us see what happens when I applied the MSO constraint. The values change as shown below.

Figure - 8: Forward and Backward Pass with Constraint
- Auto Calculated in MS Project

The values for ES, LS and also EF and LF have changed. By applying a hard constraint, we changed the dates for ES, LS, EF and LF.

This resulted in the Total Slack/Float as -1 day.

Scenario - 2: Setting a Semi-Flexible Constraint (SNLT)

In this scenario, I am setting a semi-flexible constraint on Task B, i.e., Start No Later Than (SNLT) constraint. I'll set the constraint in similar fashion as done before. The constraint date is June 30 again.

Figure - 9: Total Float as Negative with SNLT Constraint

As you can see, here again the total float/slack has turned negative for Task B. Here too, we have multiple critical paths.

Scenario - 3: Setting a Deadline 

In this case I am setting a deadline for Task B. Task B is scheduled to be completed by Friday, July 3. (Check the Figure - 1). I am setting the deadline as Wednesday, July 1. Deadline can be set from the Task information dialog box as shown below.

Figure - 10 : Setting Deadline for Task B

After I set the deadline, I pressed on OK button on the above dialog box. Now see how the schedule for the project looks like.

Figure - 11: Total Float as Negative with Deadline

In this case, again the total float has turned negative. There are now multiple critical paths as float value is negative for some of the tasks. 

Finally, coming back to our initial set of questions:

1. Can negative float exist?
Yes. As we saw, negative float can exist with various scenarios. If total slack or float is positive, it informs about the time that the task can be delayed without delaying the project's finish date. If total slack/float is negative, it informs about the amount of time that must be saved so as not to delay the project's end date.

2. Where does negative float come?
I have listed scenarios where negative float comes up for the schedules - primarily with constraints (deadline, if you think at a higher level, is also a type of constraint). So, negative total float can come up when you violate a schedule constraint.

3. What impact does negative floats have?
It lessens the flexibility of the schedule. A schedule with many negative floats is not a desirable one. The schedule also becomes quite unrealistic.

4. What impact does it have on the critical path?
There will be multiple critical paths in the network diagram now. This increases the risk of the project. Do note that critical path setting here has been done that way from Backstage View -- Options. 

5. As a Project Planner or Manager how should work on these cases?
Rework the schedule to remove the negative floats. In fact, there are cases when a schedule with negative float will not be accepted by your sponsor or sponsoring organization.

PMP Success Story: Understand the Concepts Well to Succeed

Saneesh Sukumaran achieved his PMP® credential in a short period of time – in just over one month! He was part of my class in March 2016. The day he was certified, he informed via mail, as he was then at Singapore. The happiness on being a PMP was palpable in his mail. I share his happiness.

Saneesh is an entrepreneur. He is the founder of an online start-up Wedeterna.in. I remember him to be very attentive in the class. He will ask questions only when he has thought through all the possible options in his mind. During lunch, I came to know more about his journey as an entrepreneur and also he had a number of questions on how to be a PMP.  

Today, he is a successful PMP. Go on and read his unique experience.

*********

It was a friend of mine who recommended Satya Narayan Dash’s course while discussing about PMP and that is how I attended his training session end of March 2016. I am happy to have taken my friends advice as Satya’s coaching proved to be a great asset. Even while preparing for the exam a month later I could recall the specific points he taught in the class.

PMP Coaching Experience

Satya was great in explaining concepts. While going through the course content, he gave lots of tips and tricks for understanding the concepts better. He kept reminding how important it is to spend few minutes recapping the class contents on the same day (which I regret not doing). The batch was a bunch of good people and had lots of questions. I believe being attentive in the class helps.

Own Study
Two week after the class I quickly recapped the contents that was taught at a high level, spend time with the online videos. I wanted to write the exam sooner and did not want to drag on. I used the course materials that was provided so that it helps me refresh my learnings from the classroom session. Then I applied for the PMP exam. 

Simultaneously, I also researched the study books and made a plan. I checked out Rita and after few pages, I realized it may not work for me. I checked out Headfirst and found it to be of my taste. The plan was to go with Headfirst along with PMBOK® and then skim through Rita, and then take practice questions and exams available. I also fixed the date for exams on 10th of May.

Any plan rarely works out the way you plan it. Due to various other commitments, I was left with little time to prepare. To be specific, 1st of May was the start of my second or real first stage of preparations. During my research earlier, I had realized that I did not have to remember all the ITTOs (Inputs, Tools and Techniques and Outputs) by heart. As long as I have a good understanding of the concepts, I stand a chance in cracking the exam.  With little time left I dedicated the rest of the days for preparations almost full time - full time here involved other unavoidable errands. However, the priority was to study.

In the end, I went over the Headfirst book doing almost all the exercises and the questions and referenced PMBOK thought out. Many times I read full chapters from PMBOK. Next, I took the first 100 questions at the back of Headfirst, then another 100. I was able to score more than 80%. Later, I went to Rita’s book and did all the questions available at the end of each chapter. I took as many practice tests as possible. In the meantime, I also kept revising important concepts, tools used during this period, which helped me to form a strong base on the things I learned.

My PMP Exam Experience (At the Exam Centre)

During the practice exams I was doing 100 questions in around 1 hour and 20 minutes. But I saw a pattern in my way of answering the questions, i.e., I missed something that was obvious or sometimes I mistook a word. 

I realized I need to read the questions more carefully and decided to read every questions twice before answering the questions during the actual exam. I wanted to try this approach in one practice test before the exam. But I had just one day left (already scheduled for 10th May) by that time and hence could not do that. Rather on the penultimate day before the D-day, I decided to revise what I have learned.

In the actual exam, I applied the approach of reading the question twice before answering. But I knew it won’t leave me much time with this approach. Hence to be on the safer side, I decided to answer all the questions in one go, marked the ones for review on which I was doubtful and proceeded till the end in just one iteration. 

I knew it was going to take more time than the practice tests. But it actually took longer than expected. I finished all the questions with only 20 mins left. I took a 5 minutes break, came back to exam seat and revised the questions marked for review with very little time left. I think I only changed the answer of one question during the review – the only review I could have. Fortunately for me, it worked!

Suggestions for PMP Aspirants

• The most important thing to crack exam is to have a clear conceptual understanding on how project management works as outlined by PMBOK Guide. Then you practice questions and revise your concepts to validate your understanding.
• Initially I spend few hours researching/reading on what are best checklists/notes/formula books etc. It was overwhelming. Hence, I read about people’s experiences on this blog on what they did and what they referred, which all lead back to the 1st point: understanding the concepts well. I didn't spend any more time for those checklists/formula book/notes et al; Rather I honed my understanding on the topics.
• In retrospect, one thing I would have done differently. I should have revised the classroom’s learnings the same day during my training and prepare a little for the next classroom session – as the session was spread over 4 days in weekends. I believe it would have helped me more.
