Create WBS and WBS Dictionary

00:00:00 - Continuing on our 2.0 project planning road map, this nugget
00:00:04 - is 2.2 Create WBS and
00:00:08 - WBS Dictionary. Again I have shortened it for brevity for this
00:00:11 - forum, the official name from CompTIA is 2.2
00:00:16 - Use a work breakdown structure, WBS, and
00:00:21 - WBS dictionary to organize project planning. So let's get into
00:00:24 - this nugget and see what a WBS and a WBS dictionary is all about. This
00:00:30 - nugget, as I said, is focused on creating the WBS, the Work Breakdown
00:00:34 - Structure. Consistent with the fact that this nugget comes immediately
00:00:38 - after defining the scope, creating of the WBS is the next logical
00:00:44 - step in project planning because documenting the work, the WBS,
00:00:50 - is absolutely based on the scope. We want to identify all the
00:00:55 - work required to produce all of the deliverables that we defined
00:01:03 - in the scope statement. So effectively we started with the scope
00:01:09 - that was a primary building block for Project Management. We're
00:01:12 - going to take that scope statement in the WBS, we're going to
00:01:18 - identify all of the work that's required
00:01:22 - to achieve, to satisfy the scope, i.e. identify all of the work
00:01:28 - that's required to produce the deliverables that are part of
00:01:31 - the scope definition and that then is going to be our next step
00:01:36 - in the building block for the other Project Management planning
00:01:40 - activities, i.e. the creation of the schedule, the identification
00:01:44 - of the resources, the development of the project budget. It's
00:01:49 - all going to build from the WBS. Why? I repeat myself because
00:01:55 - the WBS identifies all of the work and once we have all of the
00:01:58 - work defined then we can identify the resources,
00:02:04 - the schedule,
00:02:06 - the budget,
00:02:10 - etc. etc. which are the other nuggets in this 2.0 series.
00:02:16 - Once we have the WBS fully defined it is the most detailed view
00:02:21 - of the project. Again, it identifies all of the work,
00:02:27 - every single work package that is required to satisfy the scope,
00:02:34 - to produce the deliverables that the scope definition defined
00:02:38 - are going to be contained ion our WBS, our Work Breakdown Structure,
00:02:43 - because it identifies the work, all of the work, and only the
00:02:47 - work required to satisfy the scope statement. So again let's
00:02:54 - talk about what the WBS and how to create the WBS. So
00:03:00 - I think the first critical step is making sure we have a common
00:03:03 - definition of what is a WBS. It's easy to say it identifies all
00:03:07 - of the work
00:03:11 - and only the work.
00:03:14 - What does that mean? How do we identify all of the work? Have
00:03:17 - we written a 15-page prose that defines all of the work? No.
00:03:23 - A WBS is very much a structured
00:03:27 - definition of the work,
00:03:33 - i.e. the word S in the work breakdown structure. It is a structured
00:03:39 - definition of the work. WBSs are typically done in one of two
00:03:44 - ways. One is I'm going to describe it as an ordered list.
00:03:50 - At a high level the WBS consists of a single line that says this
00:03:54 - is my project. The high level then breaks down into major components
00:04:00 - major component number 1, major component number 2, major component
00:04:04 - 3, 4, 5 through a very large number. Major components are going
00:04:09 - to break down into sub-components sub-component 1, sub-component
00:04:14 - 1.2, sub-component 2.1 and so on and again we're going to have
00:04:18 - many major components. we're going to have many sub-components,
00:04:21 - and then we're going to break it down
00:04:24 - to the task level
00:04:27 - 2.2.1, 2.1.1,
00:04:31 - 2.1.2 and I am creating this as a hierarchy.
00:04:38 - These naming conventions are not critical to WBS but it certainly
00:04:43 - again is in keeping with our definition of the structured and
00:04:47 - it's defining the relationship that this task has with the sub-component,
00:04:54 - the major component as part of our WBS. Now for the purpose of
00:04:59 - this demonstration I have put together my WBS as three levels
00:05:03 - only with the major component, component and task. There is no
00:05:09 - rule defining
00:05:13 - how many levels a WBS has. I would suggest most projects will
00:05:18 - have a minimum of three levels but it would be not out of the
00:05:22 - question to have 5 to 10 levels
00:05:26 - of decomposition
00:05:29 - in your work breakdown structure. How far you go with your decomposition
00:05:34 - we're going to discuss this later in this nugget. We're going
00:05:37 - to give you some tips and hints to know when you're done decomposing
00:05:41 - your work breakdown structure but the work breakdown structure
00:05:44 - again is a structured layout identifying all of the work in terms
00:05:48 - of major component components, all of the work within this task
00:05:53 - group should be focused purely on satisfying
00:05:57 - the requirement to complete the work for this component, and
00:06:01 - all of these components should be satisfied exclusively on satisfying
00:06:06 - the requirements of the major component, i.e. there is a true
00:06:10 - owner-subordinate relationship
00:06:13 - within our hierarchy of our WBS. Another
00:06:18 - way of describing or defining the WBS is in a tree structure
00:06:24 - so I have exactly the same definition here, my project has my
00:06:28 - major components, my major components break down into sub-components,
00:06:32 - and my sub-components break down into tasks, and again this is
00:06:37 - three levels,
00:06:40 - the number of levels is going to be based on the complexity of
00:06:44 - the size of your overall project. Although
00:06:49 - I've kind of already described how to create the WBS it is a
00:06:54 - structured decomposition I would like to spend just a few minutes
00:06:58 - to discuss the formalities of how to create a good WBS. We've
00:07:04 - already described, defined that the WBS starts with the definition
00:07:09 - of the scope and we need to identify all of the word sorry for
00:07:13 - repeating myself
00:07:16 - required to satisfy that scope and only the work
00:07:23 - required to satisfy the scope. The
00:07:27 - main method for doing that is we start with the definition of
00:07:31 - the major deliverables.
00:07:33 - I would suggest the major deliverables are already defined in
00:07:36 - the scope
00:07:41 - and as we discussed in the scope nugget the major deliverables
00:07:46 - should be defined with the table of contents
00:07:49 - and the table of contents is probably going to be annotated to
00:07:52 - give us a very good understanding of what the work
00:07:58 - again when we described the scope we described the scope with
00:08:02 - the annotation to make sure that the business understood the
00:08:06 - content of that table of contents section but by describing the
00:08:10 - content of that table of contents section we are also defining
00:08:15 - all of the work I know I'm a broken record required to satisfy
00:08:20 - that deliverable.
00:08:23 - We then take our major deliverables with the table of contents
00:08:27 - and we validate that we can work directly from that table of
00:08:31 - contents or potentially we need to define minor deliverables
00:08:36 - or working documents
00:08:42 - to allow us to achieve the production of the major deliverables.
00:08:46 - So again we had the table of contents that says analysis
00:08:54 - of the existing system.
00:09:01 - Do we have minor deliverables associated with the work required
00:09:05 - to do the analysis of the existing system? Do we need to document
00:09:11 - the current
00:09:16 - review? Do we need to document
00:09:21 - the backlog
00:09:24 - report? Do we need to document
00:09:29 - minutes of meetings? Are there minor deliverables and sometimes
00:09:37 - the minor deliverables are only working documents that your team
00:09:40 - is going to produce that's going to be required to allow you
00:09:43 - to produce the deliverables that are required to satisfy the
00:09:48 - scope? The common term
00:09:54 - is decomposition.
00:09:57 - We start with the scope, we decompose the major deliverables.
00:10:01 - We decompose the major deliverables into minor deliverables.
00:10:04 - We decompose the minor deliverables into working documents. We
00:10:08 - may even need to do another level of decomposition to identify
00:10:12 - the work packages.
00:10:14 - For example, document the minutes
00:10:23 - if we have to interview
00:10:28 - 15 business users
00:10:32 - as part of analysis of the existing system I would suggest
00:10:39 - you need to identify additional work packages above and beyond
00:10:43 - documenting the minutes of 15 business users. The work package
00:10:48 - would say interview
00:10:52 - business user 1.
00:10:55 - The next work package would be interview
00:11:02 - business user 2 and so on.
00:11:07 - Now you may even want to decompose a little further than that
00:11:10 - where interview business user 1 has a decomposition of conduct
00:11:17 - interview, create minutes,
00:11:23 - and validate minutes.
00:11:27 - That probably is too far a level of decomposition and again in
00:11:33 - my tips and hints I'll give you some ideas of when it's time
00:11:36 - to stop decomposing
00:11:39 - but the goal is you start with the scope, you define the deliverables,
00:11:45 - you find the minor deliverables, you define the working documents
00:11:49 - required to get the work done, and then you may need to do further
00:11:55 - decomposition into the work packages
00:11:58 - to allow you to identify all of the work required to complete
00:12:04 - the scope. I was going to say and that's all there is to creating
00:12:10 - a WBS.
00:12:12 - This is
00:12:15 - the process for creating a WBS. This is a lot
00:12:21 - of work.
00:12:23 - In your scope statement you may have had 8 to 10 major deliverables.
00:12:30 - Each of those major deliverables has a
00:12:34 - TOC with 10 to 15 chapters.
00:12:41 - To create each of those 10 to 15 chapters you may have another
00:12:46 - 5 to 10 minor deliverables with additional work packages associated
00:12:50 - with that. So having 8 to 10 major deliverables it's not inconceivable
00:12:57 - to have 250
00:13:00 - to 500
00:13:02 - work packages,
00:13:04 - these guys,
00:13:06 - that are going to be required to identify all of the work and
00:13:10 - only the work required to produce those 8 to 10 major deliverables.
00:13:15 - This is the process,
00:13:18 - the process in and of itself is straightforward and simple, but
00:13:22 - don't be lulled into a false sense of security by how simple
00:13:25 - the process is there's a lot of work to decompose the scope to
00:13:31 - the major deliverables to the minor deliverables to the work
00:13:34 - packages but that's what creating an effective WBS is. So
00:13:40 - we're busy decomposing
00:13:42 - our WBS to the work packages,
00:13:45 - the key is as I just said is knowing when to stop.
00:13:49 - Well the simplistic answer is you stop decomposing when you know
00:13:54 - you've identified all of the work that's required to produce
00:13:58 - all of the deliverables. But that's kind of a self
00:14:03 - fulfilling I don't want to use the word self evident because
00:14:06 - I don't think it is self evident at all but we want to stop creating
00:14:11 - the work packages when we have identified all of the work that
00:14:14 - s required to produce the deliverables. And again we do this
00:14:17 - through the thing called decomposition.
00:14:24 - The key to stopping decomposition is this next statement that
00:14:28 - says all of the work is assigned or probably the better word
00:14:32 - is assignable.
00:14:37 - So how do we know when work is assigned or assignable? Well when
00:14:43 - we get to the point where we have identified a specific skill
00:14:47 - and/or a specific resource to do the work so we know that a
00:14:54 - BA will be the person required to conduct
00:14:58 - the interview.
00:15:02 - We know that a technical architect is the person that's going
00:15:06 - to be required to review
00:15:09 - the existing doc.
00:15:15 - The goal with decomposition
00:15:18 - is to get it to the point where we have identified a specific
00:15:21 - skill, specific resource to complete the task, i.e. it's assignable
00:15:30 - to a single
00:15:33 - resource. Now at this point in time it's assignable to a specific
00:15:38 - skill but we want to get our WBS
00:15:43 - decomposed where a single resource is assigned to a single
00:15:52 - task. This creates ownership,
00:15:58 - this assigns responsibility,
00:16:04 - and we need to get the WBS assigned to a single resource to ensure
00:16:11 - that resource understands that they are the owner of producing,
00:16:16 - completing that work package and that they are responsible. There's
00:16:20 - no saying "Oh, I thought my peer, I thought somebody else was
00:16:24 - doing this." Well no,
00:16:26 - it's assigned to you, you have the ownership, you have the responsibility.
00:16:31 - Now that can still be a very large task conduct interviews. We
00:16:37 - know we have 15 business units that need to be interviewed so
00:16:42 - I would suggest were' not done decomposing yet because we need
00:16:47 - to get it to the point that it's estimatable and measurable.
00:16:51 - If we have 15 interviews
00:16:57 - is it estimatable? Well you might say it is because each interview
00:17:03 - is going to take two hours, picking a number out of the air,
00:17:07 - therefore it's going to take 30 hours to do the job. and that
00:17:12 - could be a true statement but if we expect these interviews to
00:17:17 - be at varying levels of complexity we're going to have senior
00:17:20 - interviews for senior management interviews
00:17:26 - and we know senior management time is very hard to get and we
00:17:30 - figure at best we're going to get 30 minutes
00:17:33 - to do those interviews.
00:17:36 - Then we're going to do middle managers
00:17:41 - and they have a more detailed understanding of the system and
00:17:44 - those interviews may in fact take two hours. And then we're going
00:17:48 - to do line
00:17:50 - workers and with the line workers we're going to literally shadow
00:17:56 - them doing their job and for the line workers it may take four
00:18:00 - hours to complete the interview. So the key with taking the WBS
00:18:06 - decomposition to the point that it's estimatable is do I have
00:18:10 - enough information about the work package to be able to assign
00:18:17 - a meaningful, realistic,
00:18:20 - and measurable estimate.
00:18:26 - Thirty minutes for a senior executive, two hours for middle manager,
00:18:31 - four hours for a line worker I believe satisfies all of those
00:18:35 - criteria it's estimatable and it's measurable.
00:18:39 - If we had taken it at the high level of 15 interview 30 hours
00:18:45 - is it estimatable? Well not really because that's a bit of a
00:18:49 - guess that on average interviews you're going to take two hours,
00:18:53 - realizing that we have a very wide range of time frame, and it's
00:18:57 - probably not measurable. If we simply have this huge bucket of
00:19:01 - 30 hours
00:19:03 - for 15 interviews
00:19:07 - and our business analyst goes off and conducts the first three
00:19:13 - interviews and the first three interviews are all line levels
00:19:23 - and takes 12 hours. Remember
00:19:27 - a line level interview is going to take four hours, it takes
00:19:29 - 12 hours that business analyst is going to come back to us in
00:19:34 - a panic or at least I hope that analyst is going to come back
00:19:37 - to us in a panic and says "Steve, I've only done three interviews
00:19:42 - and I've already used up 12 of your 30 hours. At this rate I'm
00:19:46 - not going to get through all 15"
00:19:49 - that means we're satisfying our measurable criteria because we
00:19:55 - are achieving what we probably expect but our measurement, our
00:20:00 - evaluation, our project control activities are not going to be
00:20:05 - realistic. Or alternatively they didn't do the line level, they
00:20:10 - did the senior executives first, they completed the first three
00:20:14 - interviews, and they're done in two hours and again they're going
00:20:18 - to come back to you and "Steve, I think there's something wrong
00:20:20 - with this estimate. I've done three interviews, it's only taken
00:20:24 - me a total of two hours to get them all done, and I think I'm
00:20:27 - going to be done in 10 hours or whatever." So again I don't believe
00:20:31 - that satisfies our measurable activity or measurable criteria.
00:20:36 - Now the last statement on decomposition, when to stop, is
00:20:44 - we've got the interviews down, we're doing 30 minutes for the
00:20:47 - executives, two hours for the middle, and four hours for the
00:20:51 - line managers and as I discussed a minute ago do we need to further
00:20:55 - decompose that to conduct
00:20:59 - interview, document
00:21:03 - minutes, and
00:21:08 - obtain approval?
00:21:15 - If we took that 30 minutes
00:21:18 - and said 10 minutes is going to be for the interview or let's
00:21:22 - say 15 minutes for the interview, 10 minutes for the documentation,
00:21:26 - and five minutes for the obtaining of the approval it still satisfies
00:21:31 - the estimatable and the measurable and the same thing if we go
00:21:34 - in the middle management and say one hour for the interview,
00:21:37 - 30 minutes and so on, and yes it satisfies all the criteria but
00:21:43 - are we getting too specific,
00:21:52 - too controlling,
00:21:57 - too much detail
00:22:01 - and I'm deliberately using these words because I believe that's
00:22:05 - true in all of those instances. If we take it down to that level
00:22:09 - of granularity we are not giving our team members the ability
00:22:14 - to think of themselves. We probably need to tell the team members
00:22:18 - as part of conducting interviews I expect you to do the interviews,
00:22:21 - I expect you to get validation of the minutes. But we don't need
00:22:26 - to take the WBS down to the level and assign the estimates, we're
00:22:30 - simply too granular. We stop
00:22:35 - when we have all of the deliverables produced, all of the work
00:22:38 - is assigned to a specific resource at the level that's estimatable
00:22:42 - and measurable
00:22:44 - and I believe we achieved that here, that we do not need to go
00:22:49 - here. Knowing when to stop, taking our WBS to three levels,
00:22:58 - five levels,
00:23:00 - ten levels whatever it's going to be is going to again the key
00:23:04 - to stopping is we're estimatable
00:23:07 - and it's measurable and it's realistic. So
00:23:12 - we've really been through the complete process for creating a
00:23:15 - WBS scope, deliverables, decomposition, work packages, assignable,
00:23:21 - and measurable
00:23:23 - but how do we take from the deliverables
00:23:30 - to the work packages?
00:23:33 - How do we know that we need to analyze the existing doc? How
00:23:39 - do we know that we need to conduct
00:23:43 - interviews? Well one of the best ways to work through and identify
00:23:50 - all of the appropriate work packages required to produce your
00:23:53 - deliverables is to use existing guidelines. Something has happened
00:23:59 - before, someone somewhere has done something
00:24:06 - similar. Maybe there were previous projects that you have worked
00:24:12 - on, maybe there were previous projects that some other project
00:24:15 - manager in your organization has worked on but find something
00:24:19 - similar and reuse. Yes the deliverables may be slightly different,
00:24:25 - yes the end result for a deliverable for a warehousing system
00:24:30 - is going to be very different than the deliverables for a human
00:24:35 - resources system but the analyzing of the existing system, the
00:24:39 - conducting of the interviews, the various steps in the work packages
00:24:43 - should be very similar independent of the actual content in the
00:24:48 - deliverables. Find templates, buy a book,
00:24:55 - browse the web
00:24:58 - if there's nothing in your organization that looks at all like
00:25:02 - you've done there are thousands,
00:25:05 - hundreds of thousands of models out there, excellent textbooks,
00:25:10 - these things called methodologies,
00:25:15 - define the proven steps
00:25:19 - to successfully complete deliverables, to do analysis,
00:25:26 - design, etc.
00:25:31 - These methodologies could be described as industry guidelines
00:25:35 - but don't
00:25:38 - start from a blank page
00:25:44 - to do your work package decomposition, find something somewhere
00:25:49 - that's similar
00:25:51 - which is basically using analogies.
00:25:54 - What has been done? What can I reuse that looks something like
00:25:59 - this before? Now
00:26:02 - a couple more tips and hints I'm going to give you in developing
00:26:05 - a work breakdown structure. Some people prefer to do the work
00:26:09 - breakdown structure top down, others prefer to do it bottom up.
00:26:14 - I personally am a top down person and really the process that
00:26:18 - I've described is very much top down. We take the scope
00:26:24 - to the deliverables, to the sub-deliverables, to the work packages
00:26:29 - that's the top down. Scope is my project and I've done a top
00:26:35 - down decomposition.
00:26:37 - Bottom up works when you truly don't have a solid definition
00:26:43 - of scope and you start with
00:26:46 - something similar here are all of the work packages that are
00:26:51 - required, here's everything
00:26:55 - I think I need to do.
00:27:00 - Take all of your work packages, organize them into your sub-deliverables,
00:27:05 - organize your sub-deliverables into the deliverables and form
00:27:08 - the deliverables you can come up with the scope statement. Again
00:27:11 - I personally find top down to be my
00:27:14 - preferred way to work but I have worked with project managers
00:27:18 - who seem to be very successful starting with the "Here's everything
00:27:22 - that ever has to be done to get a project done." Identify the
00:27:26 - right pieces for their project and then organizing it upwards
00:27:29 - into the tree structure. And when you're developing a WBS identify
00:27:35 - the milestones what
00:27:37 - key events
00:27:41 - does the business
00:27:47 - care about?
00:27:51 - A milestone is not a work package, a milestone is the result
00:27:59 - of completing work packages
00:28:02 - and these are key events the business cares about, if you identify
00:28:06 - the milestones, build them into your WBS it makes status reporting
00:28:10 - as part of project delivery far easier and simpler for us to
00:28:14 - do. So this is really a let's get the job done faster when we're
00:28:19 - in delivery by identifying the milestones as part of our WBS
00:28:24 - and often the milestones can be directly related to the deliverables
00:28:28 - but if the deliverables are large you may need to have independent
00:28:33 - milestones potentially associated with your sub-deliverables. And
00:28:38 - a few more tips and hints to help you prepare an effective WBS
00:28:43 - involve anyone you can think of that's going to help you develop
00:28:47 - good solid realistic work packages. Involve the team, talk to
00:28:52 - the business, consult experts
00:28:57 - ask for help.
00:29:02 - Developing a good WBS is not something a project manager should
00:29:06 - undertake on their own. You need to talk to the team, the team
00:29:11 - is the people that are going to be producing the work packages,
00:29:15 - producing the deliverables rather, ask them what work packages
00:29:18 - they think they need to work on to produce the deliverables.
00:29:22 - Ask the business what work they think needs to be done, consult
00:29:26 - the experts.
00:29:28 - Take all of these
00:29:32 - and create sticky notes, put it on a whiteboard, do a workshop.
00:29:38 - Here's everything
00:29:42 - we thought of from asking all of these people what makes sense,
00:29:49 - use the sticky notes,
00:29:54 - and organize
00:29:57 - into the structure. Or
00:30:02 - alternatively complete your WBS one layer at a time. Have we
00:30:07 - identified all of the deliverables?
00:30:11 - Okay, if I complete every one of these deliverables I will satisfy
00:30:16 - the business requirements, I will satisfy the scope. When you
00:30:19 - can confidently say "I have absolutely identified all of the
00:30:24 - deliverables" then you pick one deliverable
00:30:29 - and say "What
00:30:32 - sub-deliverables do I need to complete that deliverable?"
00:30:37 - You consult the team and when you can confidently say that "When
00:30:41 - I produce every one of these sub-deliverables I will satisfy
00:30:44 - the deliverable" then you go on and say "Okay, what's the next
00:30:49 - deliverable?" and
00:30:52 - you complete that layer. And then again what are all of the work
00:30:56 - packages required to complete the sub-deliverables.
00:31:00 - Complete one layer at a time and the key is "Have
00:31:08 - I identified
00:31:12 - everything to satisfy
00:31:19 - the parent?"
00:31:22 - And when you can absolutely answer that question with confidence
00:31:25 - I have identified everything to satisfy the deliverable it's
00:31:29 - time to move on. When you're creating the WBS don't worry about
00:31:34 - the estimates. Yes, I talked about the fact that the executive
00:31:40 - estimate for the interview is going to be four hours and the
00:31:43 - middle manager sorry it was going to be 30 minutes and the middle
00:31:47 - manager was four hours and so on if you know it fine but if you
00:31:54 - don't have the detailed estimate simply ask the question "Can
00:31:59 - I later on develop a realistic estimate, a measurable estimate
00:32:04 - for this particular WBS work package?" And if you are confident
00:32:08 - that you can develop a realistic measurable estimate you're done,
00:32:12 - you don't need to estimate at this time, we're going to do our
00:32:15 - estimating in a future nugget as part of planning for schedule
00:32:19 - and development, we want to focus on identifying all of the work
00:32:23 - packages. Don't get hung up, I'm trying to do the estimating,
00:32:27 - do one thing at a time almost the same as completing one layer
00:32:31 - at a time, don't worry about the estimating, don't worry about
00:32:34 - the sequencing, we're going to do that when we develop the schedule.
00:32:40 - We want to focus on the WBS and the work packages.
00:32:46 - The estimates and the sequences come later. With
00:32:51 - the WBS fully defined we need to spend just a moment or two discussing
00:32:55 - what the WBS dictionary is. the WBS dictionary is simply the
00:33:00 - documentation of the,
00:33:07 - for the
00:33:09 - WBS itself,
00:33:11 - the work breakdown structure. The WBS dictionary is going to
00:33:15 - identify every element in
00:33:19 - the WBS, it's
00:33:22 - going to define
00:33:25 - the content of the work package,
00:33:32 - and it does that by defining each work package is going to produce
00:33:38 - a deliverable, a sub-deliverable, a working document but every
00:33:44 - component of the work package or every work package element should
00:33:51 - be building towards satisfying the deliverable so every work
00:33:55 - package is going to have a deliverable even if it's only a work
00:33:58 - document. What's the acceptance criteria? Who's going to review?
00:34:05 - Who validates that the team member has completed the work package
00:34:09 - successfully, that the deliverable, sub-deliverable working document
00:34:13 - is appropriate? What are the quality requirements? What are the
00:34:18 - time estimates? What are the milestones? What are the cost estimates?
00:34:21 - I said don't worry about these,
00:34:25 - that's still a true statement. The WBS is going to be built
00:34:30 - throughout planning.
00:34:37 - So in this nugget we're focused on defining the WBS which really
00:34:43 - probably comes down to the definition of the deliverables, what
00:34:47 - the work package content is, and what the acceptance criteria,
00:34:50 - how it's going to be reviewed. The quality requirements, the
00:34:54 - estimates, the milestones, the cost estimates, and the resource
00:34:58 - assignments are going to come
00:35:00 - in later nuggets.
00:35:03 - But we need to have a vehicle
00:35:11 - and the WBS dictionary is the vehicle for maintaining all of
00:35:15 - these information related to the work package. Now
00:35:20 - Project Plus exam will have questions related to a WBS dictionary.
00:35:27 - In my real life experience delivering projects I have never created
00:35:33 - anything formally called a WBS dictionary, I take my WBS, I put
00:35:40 - it into project scheduling software,
00:35:47 - and in the project scheduling software it will become
00:35:53 - my WBS dictionary. The project scheduling software is going to
00:35:57 - identify the WBS, the contents, the deliverables are going to
00:36:01 - be documented in my project scheduling software, the acceptance
00:36:05 - criteria, the estimates, the costs, the resources will all be
00:36:10 - simply data that I'm going to plug into my project scheduling
00:36:15 - software. Again I don't formally produce something called the
00:36:19 - WBS dictionary but to satisfy the requirements for the Project
00:36:22 - Plus you need to understand the concept
00:36:27 - of a WBS dictionary, a project dictionary, understand what goes
00:36:30 - into a WBS dictionary but recognizing that you will be doing
00:36:35 - this through your scheduling software.
00:36:41 - And when you're using your scheduling software you're not going
00:36:44 - to be having a form that pops up that says "Fill in these elements
00:36:50 - of the WBS dictionary" these are simply pieces of data that's
00:36:54 - part of using scheduling software.
00:36:58 - And I hope this statement has confused you. Elements of the WBS
00:37:03 - dictionary, the principles of a WBS dictionary absolutely apply
00:37:08 - and will be tested on the Project Plus exam. The reality is the
00:37:14 - WBS dictionary is delivered through your standard scheduling
00:37:17 - software. This completes 2.2
00:37:22 - use a WBS structure and WBS dictionary to organize project planning.
00:37:27 - In this nugget we focused on creating the work breakdown structure,
00:37:32 - we identified all of the work packages
00:37:38 - that were assignable to resource,
00:37:43 - to a skill, to
00:37:45 - a resource, that we're estimatable
00:37:50 - and we're measurable.
00:37:55 - We used this thing called decomposition
00:38:03 - to break the scope down to the deliverables, down to sub-deliverables,
00:38:08 - down to work packages and we knew to stop our decomposition when
00:38:13 - we got the work packages defined to the point that they were
00:38:17 - assignable, estimatable, and measurable. Developing a good WBS
00:38:23 - is critical because that's the building block for our future
00:38:27 - project planning activities from the WBS,
00:38:32 - we assign resources,
00:38:39 - we develop the estimates,
00:38:48 - we use this project scheduling software, and we develop a schedule
00:38:58 - and from the schedule we develop the budget.
00:39:07 - If the WBS is incomplete,
00:39:10 - if the WBS doesn't identify all of the work to satisfy the scope
00:39:14 - not only are we not going to be successful in completing the
00:39:17 - project, we're not going to know which resources, we're not going
00:39:20 - to have realistic estimates, we're not going to have appropriate
00:39:23 - schedule, we're not going to have a budget, we're setting our
00:39:26 - project up for failure before we even start. Developing a good
00:39:31 - WBS is a lot of work
00:39:36 - but it's a critical building block and it's going to produce
00:39:39 - that detailed view of your project. This
00:39:43 - concludes our nugget on create WBS and WBS dictionary. I hope
00:39:48 - this module has been informative for you and thank you very much
00:39:51 - for viewing.
