In this blog post I will start to Create the schedule, and I will show you how can get in trouble when you do it. If you want to track this Blog post, and next few one, you should download my sample mpp file. I will give you a link at the end of this post.
My first task is “Decide the Initially Budget and size and Style of the Wedding. Decide who pays for what”. After you know your budget You can determine your guest list! After that you can do the rest.
Here are the Problems.
The first task in all Summary task can start when Task “Call the guests by phone to the wedding” is finished. Why? Well, simply because after that you know how many people will come to your wedding, and you have enough information about, for example, how big should Restaurant be, how many bottles of wine you have to order, how many rooms you must reserve for your “out of the town” guests, etc.
Where is the Problem? If you decide to put all those tasks (Find a Restaurant, Find a wedding chapel, Find a Hotel Near the Restaurant,….) immediately after the ““Call the guests by phone to the wedding” task, you should ask yourself: “There are so many tasks that will start at the same day (03.08.2011)! Who should do those task?” Suppose that the Bride and The Groom decide to do all those tasks by themselves. Is it possible to do all those task in few days? NO IT IS NOT! For now, I will leave this schedule as it is, and after I build the whole schedule, and when I put (assign) resources to all those Tasks, I will see the “Over allocation” and THEN I WILL FIX IT! So, once again, I made those tasks wrong, by PURPOSE, just to show you in the future how can you correct wrong plan in MS PROJECT 2010.
Another Problem is with the Rings. I forgot the Task: “Pick up the Rings”. After you find a jewelry, and you decide on engraving, the jeweler will need some time to make those rings (this is often situation in Croatia), and to engrave those Rings.
Please look at tis picture:
Task no 36. “Find a Jewelry store and choose the Rings” have one day duration. Task 37. “Decide on engraving” should start in “parallel” with task 36. Why? Well, I can make them with the finish to start relationship (which means that I will first have to finish task 36, and after that start with task 37), but it will be silly, because it will means: “When you finish with finding a Jewelry store and choose the Rings, GO HOME, and COME BACK NEXT DAY TO SPEND 1 HOUR ON DECIDING ON ENGRAVING”. Instead of that I make those two tasks as Star to Star, which means, when you start with task 36, you can start with task 37. But, this is still not correct 100%. The best way is to make 1 task instead of two. So I will delete Decide on engraving task and I will marge it with task 36. “Find a Jewelry store and choose the Rings”
Everything is fine now. Now look at the task 37. Pick up the Rings. It has 1hour duration but in the Predecessors column you can see 36FS+ 3 days. 36 FS means that task 36 is a Predecessor and it has finish to start relationship. +3 days is LAG. Lag is also known as “waiting time”. In my example you can not pick up those Rings when you find the Jewelry store. you have to wait for some time before those rings will be ready. How do I know how much time do I have to wait!? By experience. Do not forget, that we are still in a Planning phase. When we will find a Jewelry store, and when we will decide on rings, then we will know how much time do we need. Until then that is only estimation (like everithing is )
Where to put the Lag time? Double click on the task:
Now, the another problem!
Transportation! How long will take for the transportation tasks? It depends on the Location of the Hotel, wedding Chapel, and Airport? So I put 1 hour for now, but after I will know where those locations are, I will have to change those values. Another problem I With Predecessors! when do we have to make those transport? Well, to the hotel from the airport one day before the wedding. From the hotel to the wedding chapel, and then to the Restaurant at the day of the wedding. And then, after the wedding back to the hotel, and then they after the wedding, back to the airport.
If you can recall your memory, you already know that the wedding will be on Saturday. But which one? That is what I do not know yet. After I will find it out, I will make a correction to those tasks. The same problem is with those tasks:
The “Wedding” Project isn’t so easy, after all, is it?
