Tours
Holarch in 3 minutesA tour of the CubeSat EO-1 demo project: the project home, a requirements document, the model database, diagrams, the traceability matrix and sharing.
Diagrams and SimulationAction diagrams and FFBDs, asset and SysML diagrams, spider and hierarchy views, then discrete-event and Monte Carlo simulation on the CubeSat EO-1 demo.
Traceability and VerificationThe traceability matrix, suspect links after a requirement change, the Test Center, the RVTM and Model Checks.
CollaborationShare a project with roles, discuss items in comments, review and revert changes in history, and compare against a baseline.
AI in HolarchAsk AI about the model, make a requirement measurable with a preview and undo, propose functions and test cases, and choose your AI provider.Feature highlights
Short clips, one feature each, on the CubeSat EO-1 demo project.
Requirements
Requirement Quality CheckFind weak requirements before a review does
Suspect Links After a ChangeChange a requirement, see what it may have broken
Import Requirements from ExcelFrom a spreadsheet to a structured specificationBehavior and simulation
Functional Flow Block Diagrams from TextWrite the flow as a sentence, get the FFBD
Simulation and Monte CarloWill the pass meet its requirement? Run it 200 timesArchitecture and interfaces
Analysis and decisions
Trade Studies with SensitivityA decision you can defend: weights, scores and sensitivity
Risk Register, Risk Matrix and Burn-DownEvery risk rated, owned and burned downVerification
Traceability Matrix: Click to LinkSee every gap, close one with a click
The RVTM, Generated from the ModelA verification matrix that is never out of dateCollaboration

A series that builds the CubeSat EO-1 model step by step, from the mission concept to verification and the program reviews. Watch the episodes in order, or pick the step you need.
CubeSat 00: The Mission and the MethodA tour of the finished EO-1 model: one LML model behind every document, diagram and matrix, the dashboard, the schema and the SE V.
CubeSat 01: Concept and NeedsCreate the project, capture the concept (OV-1) and stakeholder needs on whiteboards, and write the system requirements specification.
CubeSat 02: Requirements That Hold UpRun the quality check, track TBDs and TBRs, approve and baseline the requirements, then show what changed after the baseline.
CubeSat 03: Functional AnalysisWrite the top-level functional flow as text, with parallel, loop and decision constructs, and let Holarch draw the FFBD.
CubeSat 04: Operations and SimulationBuild a nominal imaging pass as an action diagram with a parallel branch, a loop and a decision, plus durations, an item flow and a resource.
CubeSat 05: Physical ArchitectureAdd assets and conduits, keep an interface register, generate the ICD, read N-squared views and allocate functions to components.
CubeSat 06: SysML ViewsBlock definition and internal block diagrams with ports, a state machine, use cases, a requirement diagram and a parametric power check.
CubeSat 07: Analysis and DecisionsMass and power budgets, TPMs, a weighted trade study with sensitivity, the recorded decision, and the risk register and burn-down.
CubeSat 08: TraceabilityA traceability matrix to find gaps, spider and tree views, impact analysis before a change, suspect links after it, and model checks.
CubeSat 09: VerificationTest suites and cases linked to requirements, test runs with evidence, failures that become issues, and the RVTM with its export.
CubeSat 10: Running the ProgramA task board, the Gantt schedule, the dashboard, a briefing presented from model pictures, DoDAF products, baselines and review documents.Systems Engineering with Holarch
A series that follows the ISO/IEC/IEEE 15288 technical processes on one small project, the WS-1 Weather Station, from mission analysis to the technical reviews.
SE 01: Mission Analysis: Define the Problem Before the SolutionCreate the WS-1 project, sketch the operational concept on a whiteboard, and link the mission, its MOEs and constraints in the model.
SE 02: Stakeholder Needs: Who Needs What, and WhyRecord the stakeholders, turn workshop notes into stakeholder requirements traced to their source, write a scenario and record the approval.
SE 03: System Requirements: Writing Requirements You Can VerifyWrite the WS-1 specification, run the quality check, fix what it flags, register an open TBD and take a baseline.
SE 04: Functional Architecture: What the System Must DoExtract functions from the requirements, decompose one, write the flow as text, read the FFBD and check requirement coverage.
SE 05: Physical Architecture: What the System IsBuild the component tree, allocate functions in the matrix, draw conduits, manage the Interface Register and generate an ICD.
SE 06: System Analysis: Budgets, Margins and SimulationA power budget read from the components, battery autonomy as a TPM, and a simulation of frost warning delivery against its requirement.
SE 07: Decision Management: Trade Studies You Can DefendA trade study for the radio link, a check of how sensitive the result is to the weights, and the decision recorded with its rationale.
SE 08: Risk Management: Likelihood, Consequence and Burn-DownBuild the WS-1 risk register, link a mitigation as real work in the model, and plan the risk burn-down.
SE 09: Traceability and Change: Knowing What a Change AffectsFind gaps in the traceability matrix, follow a requirement in the spider diagram, change it, review the suspect links and compare baselines.
SE 10: Verification and Validation: Showing the System WorksSet verification methods, write and run test cases, raise an issue from a failure, read the RVTM and validate against the MOEs.
SE 11: Technical Reviews: SRR, PDR and CDR from the ModelCheck the SRR criteria against the model, assemble and export a review package, present a briefing from the model and record the outcome.Tutorials
Tutorial 1: Getting AroundFind your way in a project: the rail, the database, the inspector, search and Help, on a small Weather Station model.
Tutorial 2: Write Good RequirementsWrite requirements in a document, run the quality check and fix what it flags.
Tutorial 3: Trace RequirementsUse the traceability matrix to find a gap, add a component and allocate functions to it, then follow the links.
Tutorial 4: Functional AnalysisExtract functions from requirements, decompose one, write the flow and read it as an FFBD.
Tutorial 5: From a Spreadsheet to Requirement DiagramsImport requirements from Excel, baseline them, fix what the quality check flags, then create spider and tree diagrams.Most videos play from YouTube (youtube-nocookie.com) when you open one; the others play from holarch.app. See the Privacy Policy.
