Group Project Part 4: Prototype Development & Testing   
Objectives:
Develop a prototype.
Conduct initial tests for functionality and effectiveness.
Prepare a Communication Plan.
Module 4:
Prototyping methods.
Basics of product testing.
Deliverables:
Update your Briefing PowerPoint document from Module Two to reflect the prototype and initial testing report. Also, update the budget with possible ways to mitigate the shortfall.
Based on the people involved in the project (Program Manager, Engineer, Logistics, Legal, and Finance), prepare a very brief Communication Plan (add it to the PowerPoint).
Scenario:
Emma gathers her project team in the familiar conference room, a sense of urgency underpinning her composed demeanor. “Welcome, everyone. We’ve reached Month (Module) Four, and there are significant updates to discuss. First, the PowerPoint presentation will need to be revised due to a change in budget and logistical issues..”
“We’re pivoting from our original ideas of reverse osmosis and distillation,” Lisa, the Engineering Lead, explains. “After reviewing the prototype challenges and the feedback from your team and the market research, we’ve decided to utilize reed beds for water purification. This simplifies our technological approach, meets the sponsors’ environmental requirements, and makes us more agile.”
Raj, in charge of Logistics, seems pleased. “That would certainly alleviate some of our logistical constraints. Reed beds are more easily sourced and installed.  I’ve started mobilizing our supply chain.”
Emma nods and continues, “We made need that agility.  The second update is some bad news – it’s financial.” 
Maria from Finance frowns, “We’ve had a reduction in our budget by $75,000. One of our funding sources – I’ve mentioned them to you before, has had to reduce its funding.  “The Lindsey Wilson Project Team may have some options to mitigate the impact.  We could aim to shorten the timeline, reduce performance features, or produce fewer units.  That’s not my area though.  Sorry for the bad news.”
Emma gazes thoughtfully at her Lindsey Wilson Project Team. “We’ll need to weigh these options carefully, understanding the impact on quality and deliverables. I’ll need that briefing PowerPoint updated by Sunday at midnight.”
Tim, the Legal Counsel, remarks, “I’ll review any legal implications of these changes, especially the shift to reed beds, and will advise.”
“Great,” Emma says. “Lastly, for this week’s deliverable, the Lindsey Wilson Project Team will also create a Stakeholder Communication Plan.”
New to these meetings, Ethan, the community outreach coordinator, is already making notes. “This is an excellent opportunity to reassess how we’re engaging with our stakeholders given the changes. We’ll define what they need to know, when, and how.”  (Add Ethan to your Stakeholder Communication Plan.  His role will be important toward the end of the project.  Also make sure the Board of Directors and Sponsors are included).
Emma feels a wave of relief wash over her; the challenges are formidable but so is her team. “Exactly. Let’s remember, adaptation is a form of progress. We’ll adjust our sails to reach our destination, even if the winds have shifted.”  Sensing renewed determination in the room, Emma concludes, “By the end of this week, Sunday at midnight, we need an updated Briefing PowerPoint reflecting our new scope and budget, as well as a simple Stakeholder Communication Plan. These are our lighthouses, guiding us through these turbulent waters.”
A chorus of agreement signals a team united, ready to adapt and forge ahead, undaunted by the ever-changing landscape of their ambitious project.
Welcome to the accelerated six-module Water Purification Project!
Your task is to leverage project management and system design principles to address an urgent issue – providing clean water in rural communities. Working in teams, you will research, design, and present a technology-enabled water purification system capable of producing at least 500 gallons of clean water per day per unit. With a generous budget of $1 million (now $925,000) for 1,000 units, you’ll focus on scalability, efficiency, and sustainability. 
Use your textbook and PMI.org resources to prepare your deliverables.
Your evaluation will be based on the feasibility, scalability, and quality of your deliverables, as well as your final presentation. Good luck!

From your Course Water Purification Project, give three dependencies that you would add to a precedence diagramming diagram.  What is your reasoning?
Your Chief Engineer, Lisa, wants more time to test the prototype on this project, and she is probably right.  How could you convince her that the schedule cannot be altered, and what is your strategic rationale?

Group Project Part 3:  Market Research and Needs Assessment 
Objectives:
Brainstorm and finalize design concepts.
Plan the design phase.
Understand the project’s risks.
Module 3:
Ideation techniques.
Planning and resource allocation.
Deliverables:
Create a 6-10 slide Briefing PowerPoint (you will update this in future modules and could/should form the basis of your final briefing in Module Six with preliminary drawings (see attached document) and technical specifications (see attached document). 

Include a summary of module one’s deliverables (scope to include budget, goal, et. al.).
Put the six-month (module) project timeline (include a simple, customized Gantt chart) on one of the slides, as well as a customized Risk Matrix for the project (see below).
Include a Risk Matrix showing the probability of risk and the impact of risk on at least six possible risks (e.g.: supply chain delay).

Scenario:
Emma finally closes her laptop, signifying a transition from planning to actionable steps. “Now, regarding deliverables, we need to complete a Risk Matrix by Sunday midnight, and then the Lindsey Wilson Project Team will coordinate with the Engineering team to prepare a PowerPoint summarizing the prototype’s current state. These are non-negotiables; they will help us recalibrate our expectations and tactics moving forward.”
Lisa nods, acknowledging her role as Chief Engineer. “Sidd is out today and I know we’re behind. I expected to have the technical solution to the Lindsey Wilson Project Team by the end of last week, but it didn’t happen.  The focus will be on the technical setbacks we’ve had, what alternatives we’re considering, and the most feasible paths forward.  We’re still cautiously optimistic.” Emma appreciates Lisa’s straightforward approach; it’s needed during this trying time.  She hopes the Lindsey Wilson Project Team will not be too upset with her for the delay.  “Also, we are going to be over budget, $510,000 for R&D instead of $500,000.”
Ignoring Emma’s slight grimace, Tim adjusts his tie and interjects, “Please make sure that the geopolitical events in the Middle East are on the Risk Matrix.” With his legal background, his stoic face doesn’t conceal his concern but underlines the gravity of the situation.
Maria, ever pragmatic, chimes in, “I’ll continue to monitor the non-profit’s financial situation. As soon as I have something definitive, I’ll let the team know. Meanwhile, shifting budgets should also be in the Risk Matrix.” 
Raj nods, “So should potential supply chain issues.”  He motions to Lisa.  “Our proof of concept testing will be in India, as it has the most modern infrastructure.  Initial components are already on the way.”
Emma leans back in her chair and surveys the room – each person absorbed in their respective challenges but bound by a common goal. “Excellent. Remember, the Risk Matrix and the PowerPoint presentation are essential for our next steps. These deliverables are more than just assignments; they’re critical tools that will inform our strategies and decisions moving forward.  Lindsey Wilson Project team, you are the ‘quarterbacks’ of this effort and I’m confident in you.”
The atmosphere is tense but energized, each member understanding that the project’s aspirations are as immense as its hurdles. Emma concludes, “We’ve got a mountain to climb to meet budget, schedule, and performance objectives, but remember, the view from the top makes it all worthwhile. So let’s buckle down and get this done.” 
A chorus of agreement fills the room as everyone begins to pack up. They leave with a mixture of trepidation and resolve, but above all, a sense of purpose that reignites their commitment to the project.
******Late in the week, Lisa, the Chief Engineer comes up to you, the Lindsey Wilson Project Team, with an apology and the initial product design.  “I know it’s late, but the scope change made us rework the prototype.  Also, Sidd is now out with a broken ankle.  Football, ugh.  Anyway, here it is.  We are pretty certain that reed bed filtration systems will be the best technical solution, so please let us know what you think.”See the attached document:

In your team’s Course Water Purification Project, what are some potential sources of conflict do you see between your project team and the various competency leads: Engineering, Logistics, Finance, Legal, even the Program Manager herself?  How will you deal with those conflicts, up to and including, your Project Team missing some deadlines because other team members missed their deadlines (like Lisa from Engineering being late with the prototype document because Raj got hurt playing football?)

Group Project Part 2:  Market Research and Needs Assessment  
Objectives:
Identify customer needs.
Assess market demand and conditions.
Module 2:
Market research techniques.
Conducting needs assessments.
Deliverables:
A 2-3 page Market Research Report detailing customer needs and existing solutions in the market (add References per APA).
The prototype is late – prepare an email informing the Program Manager.
Scenario:
The air is thick with tension in the conference room where the project team has gathered. Emma, the Program Manager, looks up from her laptop momentarily, looking up to address her team. “Thank you for the project scope document.  I know that you are working on some market research for next meeting’s deliverable.”
Lisa, responsible for the Engineering aspect, and Raj, in charge of Logistics (both are your Subject Matter Experts (SME’s), are clearly anxious. “Okay team, we’ve got some issues to discuss, and they’re affecting our timeline. Let’s address these head-on,” Emma initiates the conversation. “The project scope has changed – well, at least clarified.  Our sponsors are insisting that the technical solution be environmentally sustainable and climate-friendly, so that eliminates several of the options we were considering.  It must use renewable energy sources.”
Lisa sighs and pushes her glasses up her nose, “I have to admit, the prototype’s development isn’t going as smoothly as we’d hoped. With this scope change, we are facing challenges with the renewable energy component that we just didn’t anticipate. Sidd is working on it but It may… set us back.” Emma glances at her Gantt chart, thinking of the cascading effect this could have on other parts of the project. “Lindsey Wilson Project Team, let me know by the end of the week.”
Raj chimes in, “And that’s not all. I’ve been doing some calculations on the logistical side. Given the road conditions and the remote locations where we’re planning to deploy, we might also face delays in delivering the materials and units.  There are also some, um, geopolitical events going on in the Middle East, of course.” 
Tim, Legal Counsel, nods in agreement.  “I’m monitoring local, US, and UN guidance around ongoing unrest, sanctions, that sort of thing. India and even Africa are going to be less challenging than the Middle East.” 
Maria from Finance replies, “Nothing from me, but part of our funding comes from a non-profit that is facing some pressures.  I’ll advise when I know something, but for now he $1,000,000 budget seems do-able.”
Emma looks around the room at her Lindsey Wilson Project Team – each face reflecting the weight of their ambitious project. “Alright, we’ve got challenges, but we also have an opportunity to innovate and solve real-world problems here. Lisa, please brainstorm alternate energy solutions in the next couple of days to see how we can catch up. Raj, can we find local partners in the deployment areas to mitigate some of these logistical issues?” She pauses for effect. “This project’s impact could be huge, and that’s why we chose it. It’s also why we’re going to adapt and overcome these challenges.” There’s a murmur of agreement and renewed focus as the team prepares to delve back into problem-solving mode, each committed to steering the project back on track.
******
Late in the week, Lisa, the Engineer, comes to you and says, “I apologize.  I know I promised the prototype specs to you this week, but it won’t be until next week. The scope is going to change to include a reed bed for water filtration. Will this delay the fielding of the project at the end of six months?”  You think about it… you are working on the Market Research Report. This delay will delay the project, but can the team still meet the project deadline?  Prepare an email informing the Program Manager, and let her know your thoughts.

Regarding the module’s lesson, and the Course Water Purification Project, for each of the remarks made below, what types of interpersonal influences could exist?  Discuss the potential pros and cons of each. 
Maria, the Financial Analyst says, “I’ve had good working relations with the Legal department. They like me and I like them. I can usually push through anything ahead of schedule.”
One of the engineers, Sidd, was overheard making the following remark to a team member: “I know it’s contrary to department policy, but the test must be conducted according to my specific criteria or else the results will be meaningless.”
Emma, the Program Manager overseeing all of VitalSphere’s projects says to a colleague, “Ultimately, I’m the one in charge, and I have to make the hard decisions, even if the Project Team doesn’t like it.”

Group Project Part 1: Project Initiation and Scoping   
Objectives:
Understand the problem statement.
Define project scope and objectives.
Module 1:
Introduction to the water crisis.
Basics of project scoping.
Deliverables:
A 2-5 page Project Scope Document outlining objectives, target audience, and limitations.
Scenario:
On a bright Monday morning, the atmosphere in conference room B is tinged with a mix of anticipation and focus. Emma, the Program Manager and project sponsor, takes her seat at the head of the long glass table, her laptop open. She looks around the room, taking note of the key members of the cross-functional team: Lisa from Engineering, Raj from Logistics, and several other domain experts who will form the backbone of the Water Purification Project for Rural Communities. You and your team are there as the project managers.
“As you all know,” Emma starts, “we have just six months to develop a scalable and efficient water purification system, and we have a budget of $1 million to create 1,000 units. This is a highly ambitious project, and it’s vital for enhancing the quality of life in rural communities that lack access to clean water.”
Lisa, the Engineering Lead, nods and chimes in, “From the engineering standpoint, we need to focus on using sustainable materials and renewable energy sources. I propose we create a sub-team to conduct rapid prototyping by the end of month (module) two. That way, we can quickly figure out the technical limitations and possibilities.”  Sidd, her deputy engineer, smiles.  “We’re on it.  We are considering..” (he reads from his laptop):
“Reverse Osmosis: A highly effective method for removing a large majority of contaminants from water, although it’s generally more expensive and energy-intensive.
UV Treatment: Ultraviolet light can be used to kill bacteria and viruses, although it doesn’t remove chemical contaminants.
Activated Carbon Filters: These remove organic compounds, improving taste and odor. They can be used in conjunction with other purification methods, but not stand-alone.
Ceramic Filters: Effective for removing bacteria and protozoa, but not viruses or chemical contaminants.
Reed Bed Filtration: Low cost once established, effective, sustainable, environmentally friendly.
Distillation: This involves boiling water and collecting the vapor, leaving contaminants behind. While effective, it’s also energy-intensive and can be slow.
Chlorination: Adding chlorine is an effective way to kill bacteria, but it’s not as effective against some other types of organisms and can leave a residual taste.  Also, it is tricky to ship large quantities.”
Raj, the Logistics Manager, leans back in his chair and interjects, “Thanks, those are interesting options, and each has its challenges to ship and install.  We’ll also need to consider shipping and storage, especially since we’re talking about deploying these units in rural areas. Road conditions, climate, and local resources could all be factors. So, I’d like to parallelly conduct a logistics survey to understand these challenges better.” Emma smiles at both of them, impressed by their foresight. “Excellent points, both of you. Let’s include these action items in our project scope document, which our Lindsey Wilson project management team will work on. It’s going to be a demanding six months, but if any team can pull this off, it’s this one.”
Maria, the Financial Analyst, and Tim, Legal Counsel, both nod.  Maria says, “The $1 million budget looks appropriate, and we will try to procure funding based on that amount.  Our initial plan shows a $500,000 Research, Development, and Testing budget, with a $1000 per unit production and fielding cost once we settle on the technical solution.  So $500,000 for fielding all 500 units during the Execution phase.  One million total.”
And so, with a clear yet ambitious project scope, the team dives headlong into what promises to be an intense, transformative journey with a clear yet ambitious project scope, the team dives headlong into what promises to be an intense, transformative journey.

This week’s assignment we are going to investigate what threat information is being shared in the water and wastewater purification sectors. In our role as Vice President of Zenith City Water, we need to identify the threats that exist in our sector.
Assignment Guidelines
Step 1: Using a mixture of many different sources, you will be going out and finding the latest threats against your company’s sector. Try and answer the below questions and others you may think of.
Which APTs are currently going after other companies in your sector?
What tools are being used to go after the computer systems?
How successful has the group been?
Are the threats focused on a specific location for the victims or are they going after everyone equally?
Has law enforcement been brought in? Has law enforcement had any leads yet?
Step 2: Once you have gathered up all the information you will compile the data into a Word document of approximately 4-5 pages of content in a business memo formet, excluding the cover page, references, etc. Make sure you address the various questions listed above and other questions you developed from your research. 
Step 3: You need to include a single paragraph at the end stating if you think the company can weather the current atmosphere. This document will be viewed by various key personnel throughout the company.

 
This week’s assignment we are going to investigate the more devious side of things. Based on your work from ISSC477 and the MITRE ATT&CK for ICS paper, you will be describing how someone can successfully attack and/or hack a PLC.
Assignment Guidelines
Step 1: Read the MITRE ATT&CK for ICS paper and look at the webpage https://collaborate.mitre.org/attackics/index.php/Groups .
Step 2: You will chose either one of the attacks listed on the webpage or if you are adventurous you can find a PLC attack of your own. Your focus on your research and data gathering should be focused on what happened in the PLC/SCADA attack. A 4-5 page paper should be sufficient to answer some of the following questions.
What PLC/SCADA system was attacked?
Which organization was targeted?
Who attacked the target?
How did the attacker gain access?
What was the rough timeline of the attack?
